Do you have to use a nanoscissors to cut nanotape?

Residue

Has anyone looked into or considered nano tape?  I’ve put some on glass, and can’t detect any reissue after pulling it off.  But it’s so strong it’s a bit scary.

Ha Ha, I remember the old poster size sheet printed with green ink that used to come with Rega turntables contained the following line "any dust that accumulates on the stylus can be easily blown off". I never went for ultra expensive cartridges, but could see this item being of particular concern to anyone who now will be anxious that their $Xk cartridge is somehow compromised. There is one thing, did anyone using said product notice anything horribly wrong prior to Fremer's post? 

Depending on who you listen to there is something potentially wrong with nearly any of them (liquid ones, magic eraser, blutak, onzow). 

Update: Here's a little ditty I found interesting on this subject on Youtube:

Is The Onzow Zerodust RUINING Your Stylus? - YouTube

Yes, fantastic post @rickd1225 !

Everyone who missed it - scroll down and read it.

@rickd1225 

Thank you! Expertise over speculation 100 times out of 100 !

Also having no dog in this fight, I will continue using Onzow.

As many have pointed out, there is nothing wrong with occasional brushing & flossing so to speak. Occasional use of a compact brush as supplied by Ortofon/Benz/Lyra/MoFi/Disc Doctor etc as an addition to regular correct use of the aforementioned gel is highly advisable. Gentle lossy brushing of the cantilever could also be considered from time to time.

I agree that hard clear substances can build up on styli. I have seen it and cleaned it. Not rocket science but it does require great magnification and a steady hand (along with support of the cantilever using MacGyver inspired well placed removable scotch tape with the unsticky back side supporting the top of the cantilever). Clear buildup is indicative of cleaning “treatment” fluid whereas brown gunk would relate to wet record playing trash which is typically not as tough to remove.

The clear crust I’ve removed via an exacto knife (Metal blade) & plastic pick were determined, by user/owner query, to be stylus treatments over applied and built up over time. The brown gunk, removed with just the plastic pick, was one of my pickups grunged up after trying to relive my youth using a wet Discwasher record brush - turns out they don’t effectively dry after moistening the brush’s leading edge!

In spite of a potential warranty claim reported for a mistracking cartridge, I completely fail to see how such a soft cleaning gel can cause audible damage despite referenced “deposit” photos.

Just my $0.02 worth . . . Let’s go buy more records!

@rickd1225, God Bless You for your expertise on this!

I have no idea what all the technical polymer chemistry stuff means but, like you, I've been using the Onzow Zerodust stylus cleaner for a while, now, with no unsavory effects I can discern. No problems with sound quality and nothing of any concern I can see on the stylus. However, the magnification I've been using to observe the stylus is pretty pedestrian. I also agree that Mr. Fremer, WAM Engineering/Wally Tools and J.R. Boisclair have gone off half-cocked on this. Strictly based upon what has been reported, thus far, however, I have to say, regrettably, that the brunt of responsibility, here, rest squarely on Mr. Fremer's shoulders.  WAM/Wally Tools/J.R. Boisclair are simply reporting on what they're seeing, thus far, and what the styli owners have, it would seem, reported to them, regarding these styli deposits. It wouldn't surprise me, at all, if Onzow Labo, DS Audio and maybe some other manufacturers of some of these gel-type cleaners consider litigation if their sales are negatively affected by this half *** reporting. It would behoove Mr. Fremer to do everything within his power to get to the bottom of what these deposits really are and where they are really coming from and do it FAST!

I have a 47 year history in the chemical business, much of which has been involved in polymer chemistry. I have years of formulating and specifying both epoxy and polyurethane coatings, adhesives, sealants & elastomers, aka CASE chemistry. I am now retired.

The Onzow product is very likely to be a elastomeric polyether polyurethane. There would be no need for a fugitive plasticizer in this product as the urethane can be formulated as soft as the Onzow is. Unlike PVC used to produce records that does have a plasticizer. Polyurethanes are reactive 2 component chemistry consisting of the reaction between a Polyol (multifunctional alcohol, think -OH)and as stated it would be a polyether polyol. This is reacted with an aliphatic isocyanate to form the clear water-white polyurethane. This reaction is Not Reversible. The formula would also likely be over indexed with the Isocyanate. Any excess isocyanate not crosslinkied with the polyol would be further reacted with atmospheric moisture, water is H-OH, so it has the -OH available to react. Therefore, there is no fugitive material available to “gum” up the stylus/cantilever. Now the vinyl records do have additives than can be fugitive that could gum up the works. Without chemical analysis we do know what the deposits are. That needs to be determined before jumping to any conclusions.

In regards to using wet cleaning of styli using alcohol or other solvent based solutions this should not negatively affect the epoxy adhesive used to bond the Diamond to the cantilever. Especially if using the recommended drop of solution. Even direct full immersion would take days, weeks and possibly months to have any deleterious effect and even then removing from immersion it could recover. A correctly formulated epoxy adhesive is resistant to solvents except for the most aggressive types like methyl chloride. No manufacture would use this aggressive of a solvent in a stylus cleaner. 
 

I am currently an Onzow user. I have not noticed any deterioration in sound quality since beginning to use it about 1 year ago. I don't have access to a high resolution microscope to inspect my stylus to see what might be there.
 

 I don't have a dog in the fight, but my chemical curiosity has me wondering what is happening. I await further investigative results to determine what is really going on.

@oldaudiophile 

Yep, if I take anything from this saga, it's that a liquid stylus cleaner is good to have in the toolkit. I'm not intending to use it daily or weekly - but maybe every once in a while, and definitely to clear up accumulation on previously used styli - I think it's a good idea to have on hand. I just ordered some Last cleaner. Heck I ordered some Stylast too, though I'm not sure yet which cartridge I want to try it on. 

For what it's worth, even though I will absolutely hate going back to using a stylus brush, with or without cleaning fluid, distilled water, purified water, alien Elixer or whatever, I'm now doing some research on liquid stylus cleaners. I asked Music Direct what "both a stylus cleaner and a stylus preservative" meant with regard to Mobile Fidelity's LP#9 liquid cleaner. They responded by saying this solution does not leave behind any kind of coating on the stylus. So, apparently, the mention of "preservative" alludes to the fact that a clean stylus will last longer. LAST Stylus Cleaner basically advertises the same effect but, unlike LP#9, they say their solution does not contain alcohol. They also say their solution removes the most stubborn crud. Mobile Fidelity and The Last Factory are two authoritative sources I have the utmost respect for. I was going to add Michael Fremer to that list, too, because of his support for Audio Intelligent Stylus Cleaner. However, after this latest half *** stunt of his in Analog Planet, he's gone down a couple notches in my pantheon of trusted sources, if you know what I mean.

I don't blame MoFi for not wanting to wade into this one. A very reserved and measured response, with a sales pitch too, lol!

He's right though, in pointing out that too many audiophiles are too skittish about applying proper brushing. And in comparing that to the (usually greater) forces it encounters during normal playback. Again, watch a stylus slam into the 1st music groove after being dropped in the outer lead groove of a spinning 12" 45 RPM. 

OK, boys & girls, here's the response I received yesterday from Mobile Fidelity Sound Lab:

"We still recommend the classic – LP#9 Stylus Cleaner with an appropriate stylus brush. While we definitely understand the anxiety that comes with having to make any contact on a nice stylus, as long as you are brushing the tip lightly from back to front a couple times there is no risk of damaging the stylus. You have to consider that the tonearm itself puts as much or more pressure on the stylus with daily use – they are definitely fragile, but as long as you are following the proper cleaning technique there is nothing to fear!

I personally don’t have much experience using any of the “gel in a tiny tin” cleaners so I can’t speak much as to their effectiveness compared to a cleaner and brush, but if you are worried about damage from using those then I firmly believe the “if it aint broke, don’t fix it” mantra applies here. Hope this clarifies, let us know if you still had any other questions!

Customer Service

Mobile Fidelity Sound Lab"

Kind of assumed they would recommend their LP#9 which, BTW, the Music Direct website states is "both a stylus cleaner and a stylus preservative". It's not clear, to me, what "preservative" really means in this case (e.g. putting or leaving behind some sort of chemical coating on the stylus or just the inference that a clean stylus helps preserve or prolong its useful life). Can't imagine it would be the former because the Music Direct website also states it "contains a Mil Spec IPA (Isopropyl alcohol)".

Yeah, I was thinking maybe it could affect SQ via added tip mass. And since rigidity is key in this part of the assembly to accurately transmit vibrations, any compliant/damping goop on there could slightly "muddy" the transmission. But beyond that, the pics mostly seem to show the accumulated goop on the stylus shank, not the actual contact lines of the tip (the cantilever crap looks more like a total failure to clean up there). Maybe the tip is actually "clean enough" as far as groove contact goes? But the question on stylus life is a good one.

Either way, a good cleaning regimen would keep all bits - tip, shank, and cantilever shiny clean like new, which must result in the best playback performance. Don’t ONLY use the Onzow or DS Audio pads.

Insofar as a deposit has mass, it cannot help but affect SQ, I would think, by adding mass to the moving mass of the stylus/cantilever.  It is unlikely to have no effect. The deposit can also affect how the stylus tip sits in the groove or alter the normal stylus contact patches.  Not good either.

My biggest questions to MF, which have NOT been answered, is regardless of whether the Onzow leaves a deposit on the stylus ( which IMO has NOT been absolutely proven yet) is a) is the stylus deposit in any way detrimental to the stylus life, and b) does it impact the SQ? These may be difficult questions to answer, but I would think that if the answer was yes to either question, that would have been determined years ago by the numerous users of the Onzow.

Here's some news or, rather, pseudo-news from someone who claims to be the New Zealand DS Audio Distributor, on behalf of someone named Aki who is... the creator of the DS Audio gel stylus cleaner? Not terribly clear! This was posted recently as a comment under the follow-up article in Analog Planet:

"Hi Stephen here from Soul to Sole Audio.... I am the New Zealand DS Audio Distributor and Aki has been made aware of the comments, regarding his ST-50 Stylus Cleaning Pads, that have been dragged into this conversation about Zerodust.

Here is the info he has posted:

"DS Audio designed and manufactures our ST-50 stylus cleaner for numerous good reasons. Before developing the ST-50, many people used a liquid-type cleaning brush with resulting problems such as compromising stylus adhesive and oxidation of metal parts. There were instances of customers damaging the stylus/cantilever using a small brush for the cleaning or impacting the cartridge suspension by brushing incorrectly.
This is why we developed the ST-50 pad-type stylus cleaner. It is mechanically safer and there is no chemical fluid that may damage the cartridge. The shape of the pad and its low profile allows you to cue down the stylus gently on the pad with no cantilever contact.

We specifically chose a lab grade of urethane gel that is ether based. The two basic formulations of urethane, ester and ether, have some important differences. Water attacks ester-based urethane, causing a significant reduction in physical properties. Ether urethanes exhibit far superior hydrolytic stability (water not reacting with another chemical), especially in humid environments. Ether-based materials also resist fungus growth better than ester-based materials."

Don't know how you folks feel about this comment but, to me, as a non-chemist consumer audiophile, this is nothing but obfuscation. This comment is like that scene in "Peanuts" where Lucy pulls away the football right as Charlie Brown is about to kick it. Misses the point entirely! Stating that the DS Audio gel cleaner is "mechanically safer" is reassuring but I think most of us who bought a gel type stylus cleaner figured that out before we bought one. Indeed, I think that's why most of us bought one in the first place! We still need or would like to know what the deposit or deposits on the styli are. No news from the Wally Tools Lab on this in a week and nothing of any substance on this from Mr. Fremer in longer than that. If Mr. Fremer isn't closely following up with Wally Tools Lab/WAM Engineering's J.R. Boisclair on this, I will consider this extremely irresponsible! If these folks end up leaving us all swinging in the wind on this one, it will be tantamount to starting a fight in a bar and, then, cowardly slinking out the back door!

I must confess I'm more than a little disappointed we haven't seen or heard much in the way of substantive follow-up, lately, on this question from Mr. Fremer, WAM Engineering, Wally Tools, Onzow, DS Audio or whomever. Seems all the audiophile gods have been silent for a while, now.

I contacted Mobile Fidelity a few days ago to see what they might recommend with regard to stylus cleaning and, also, to see if they had any thoughts about the Onzow Zerodust or gel cleaners, in general. They've never failed to respond, yet. When (or if) I get a response, I'll share. In the meantime, here is my experience with regard to using the Onzow:

I haven't been using the Onzow for very long. Only records I've ultrasonically cleaned, first (even new ones), have been played on my relatively new TT & cartridge. I use the Onzow before and after every side. All my records are in anti-static poly sleeves and have been very well cared for and stored since I bought them. All the records I've played have been treated with LAST record preservative. I use an AudioQuest carbon fiber anti-static brush before & after every play. For what it's worth, I also use a Michell record clamp. One change I'm going to make, now, is to use the AQ brush BEFORE I use the Onzow and immediately after, right before play, instead of using the Onzow, first, and brush, second, right before play. Probably obsessive overkill but what the heck! Doesn't really take that much time.

When I use the Onzow, I do not free-hand it (i.e. raise it to the stylus by hand). I set in on a little block, on the plinth, at the proper height, so I can use the TT's cueing lever to lower the stylus onto and off of the Onzow's gel pad. I do this 2 or 3 times, moving the block & Onzow around just a little each time to give the stylus a clean landing spot each time. When I first started using the Onzow, I didn't notice any deposits on the gel pad at all and wondered if my records and stylus were really that clean. However, lately, I've noticed ever so tiny little black spots or specks, here & there, on the Onzow gel pad. I'm assuming this means the Onzow is doing what it's supposed to do. Is it getting everything? I've used the magnifying cover of the Onzow box and, also, a very small hand-held stylus microscope I have to examine the stylus. However, both of these are extremely limited and don't really give as good a view of the stylus as I'd like. I just might invest in a jeweler's loop or something better. From what little I have been able to see, the stylus looks relatively clean. I can't really say with any degree of certainty what the black spots on the Onzow gel pad really are. My assumption has always been that it's probably whatever dust & crap the Onzow picks up from whatever the stylus picks up in the grooves. My non-scientist's assumption has always been that these tiny black specks are probably PVC shavings from the records, dust and whatever other crap hides in those grooves. LAST treatment or not, considering you've got a highly polished diamond doing a complicated dance in those tiny little PVC grooves, the friction and heat going on in there has to be wearing away some amount of PVC. Anyway, that's what my non-scientist's mind without an electron microscope has always thought.

As for continuing to use my Onzow or going to a liquid cleaner, dry stylus brush, stylus brush with distilled water, ultrasonic stylus cleaner, combination thereof, etc, etc, etc,, I haven't decided, yet. There are SO MANY opinions on this! It would be nice to see a showdown review or several showdown reviews on this with a healthy amount of scientific acumen applied, including, of course, electron microscope shots. However, I doubt this will ever happen. Something like that would put some people & products out of business. Then again, there are some minds impervious to science who would just go on using whatever they firmly believe in, anyway. So, I don't see the harm. Might even be a good marketing investment.

I've used a stylus brush and liquid cleaner in the past and would really, really hate to go back to that! Music Direct has said, in the past, that they use the Onzow and, occasionally, Mofi LP#9 for stylus cleaning. Don't know if they are still using that approach. I'm not sure if Mofi LP#9 is a non-solvent cleaner, per se. Fremer says he subscribes to the use of non-solvent cleaners and uses Audio Intelligent stylus cleaner, an enzymatic formula. Aren't enzymes just another solvent? If memory serves correctly, I believe LAST stylus cleaner is also a non-solvent formulation. I'm sure there are probably other non-solvent type liquid stylus cleaners and all sorts of other concoctions out there, as well. As for the Onzow gel breaking down over time, I can't remember where I read this; might have been reviews, but I do recall reading that this gel is supposed to last a very, very long time; virtually forever, even after cleaning (by running warmed distilled water over it). Nothing lasts forever! And then, of course, there's Magic Eraser, BlueTack, etc., etc.

What's a poor confused vinyl head audiophile to do?

In the end, I suspect we may very well learn that many, if not all, of the different reputable stylus cleaning approaches are effective; just different. Either that, or we will all be left to our own devices and this will prove to do be much ado about nothing, like many things in audiophilia nervosa.

@mulveling .. +1 on this:

"Whatever cleaning regimen you choose, full stylus & cantilever brushing should be a part of it."

Sometime over the last week my vinyl lost some of the magic. As part of this Onzow gunk thread, I've been scrutinizing my cartridge with 8X magnification. From both sides, from the front, from the back. Seems a small hair or fiber wrapped itself around the cantilever and was acting as a leash on the motion. Very carefully unwrapped it since just a back to front brushing wouldn't dislodge it. Adding regular magnified cartridge inspection to my routine.

@oldaudiophile 

Thank you for the follow-up with Onzow's response!

I'm in no position to make a scientific assessment or educated guess, so here's my uneducated guesses:

The stylus gunk show in the infamous pics is simply mold release agents and other crap from vinyl records, accumulated over time. The Onzow and DS Audio gel dips are NOT abrasive enough to fully prevent this buildup, over time. They DON'T contribute to the gunk; they're the wrong bogeyman. They simply aren't powerful enough to clean it off. Regular dry brushing, and ME dips may or may not be enough to prevent gunk accumulation. Occasional regular liquid cleaner use, the ME "scrub" methods, and/or ultrasonic cleaners are almost certainly strong enough to prevent gunk buildup when used properly & regularly. 

All of the pics show a filthy, disgusting cantilever that is the telltale sign of an inadequate cleaning regimen. Whatever cleaning regimen you choose, full stylus & cantilever brushing should be a part of it. 

This is a recommended cleaning practice from U Turn.

An "oligomer" is nothing more than a short "polymer". So, all oligomers are polymers but not all polymers are oligomers. Further, the distinction is vague; the number of units or "mers" that define an oligomer is not specified by the term. One dictionary definition says an oligomer contains from 2 to 100 units, for example. So, to say that a molecule is not a polymer but is an oligomer, does not say much, and it’s technically incorrect. It just means the chains are shorter than long.

I am still wondering about Peter Ledermann’s beef with Magic Eraser. Maybe because of this controversy about Onzow, I just examined a few of my cartridges that have been regularly exposed to ME under my Olympus laboratory microscope, and I see absolutely no problems. Further, the areas of the cantilever that do come in contact with ME are much cleaner than the top side of the cantilever (between the cantilever and the cartridge body), where the ME cannot reach.

In the old days, I used to clean styli with Stylast.  I never had a problem, but I did not own the Olympus Microscope or even think about close examination of the styli back then. I do think it's prudent to avoid liquid cleaners.

@oldaudiophile thank you for your follow up.

Still have my reservations. And I am going to pull a stylus and take it to our lab in Ohio to see if we see any residue. 

Just thought I'd post this as a follow-up, for what it's worth. I got tired of waiting for people like Michael Fremer, WAM Engineering and J.R. Boisclair to do the obviously right thing under the circumstances (i.e. ask the manufacturers or makers of Onzow Zerodust and other gel stylus cleaners for their feedback or response). So, I took a stab at it. I was hoping for more detail. However, I'm just some guy, some audiophile out there in the great ether asking general questions about their product. I would assume someone with considerably greater stature in audiophile circles would get a more substantive or in depth response. I would think Michael Fremer, at least, owed that to his readers & followers. I hope Onzow Labo takes the time to read the articles published in Analog Planet and respond directly. Anyway, here's the response I got from Mr. Akira Ishibashi of Onzow Labo of Yokohama, Japan:

"Thank you for your inquiry:

We carefully select resins that do not build-up residue from the beginning of develop ZERODUST. No residue build-up to the stylus. The materials are completely different from the products of other companies. ZERODUST has no adverse effect on vinyl records too. This is because ZERODUST is made of material with the same properties as mold release agent used when pressing records. Please use it with confidence.

Sincerely,

Akira Ishibashi

Onzow Labo"

Yes! This is certainly disconcerting news for those of us vinyl heads who never liked free-handing stylus brushes. Every time I did that, I channeled a special ops sniper holding his breathe before squeezing off a round! The Onzow and some of the other goop stylus cleaners, handled appropriately (i.e. not free-handing, as some instructions advise, but locating a safe, non-movable spot at the correct height so as to allow just the tip of the stylus to contact the goop; not the cantilever and using the TT cueing device to lower & raise the stylus into & out of the goop), seemed like the perfect solution! DAMN! Now, it's back to channeling the special ops sniper?

Some have criticized Mr. Fremer and WAM Engineering for this sort of half-baked alarm. However, half-baked notwithstanding, I would rather know about stuff like this before continuing to use my Onzow. The first article stated: "An analysis of the residue shows it is not silicone but rather a polymer of some sort." Then, in the follow-up article Wally Tools said: "I got more news from the lab yesterday (it is coming in slowly) and the material is an oligomer, not a polymer, so it can't be polyvinyl chloride." I'm not a chemist. So, I Googled "oligomer". Some sites say it is a polymer. Some say it's a polymer intermediate. Well, is or are the residual deposit(s) still "not silicone"? Isn't the Onzow and some of the other goop cleaners silicone or silicone-based? If it's "not silicone" would it be reasonable to conclude these residues are not coming from the Onzow and silicone-based goop cleaners? Is it possible use of these goop cleaners cause, in some or any way, the build up of these deposits? Seems, to me, we need to know where this or these deposits are coming from and exactly what they are. At this point, we are all chasing our tails. It also would be instructive to know if this or these residual deposits are all the same from one stylus to the other. There are simply not enough controls, thus far, to come to any hard & fast conclusions. It would be great to hear from Onzow, DS Audio and the others.

I was surprised to learn from the articles, that the DS Audio left residue also.

I believe their gel is “clean room” quality + the flat surface seemed safer to use than the Zerodust. I’ve stopped using both ( for now) in favor of a brush used by professional photographers. 

@daveyf    “Maybe a better question would be to ask..and verify, IF a reduction in SQ is heard by any of these ’deposits’.”
 

+1 Yes, my first thought as well. 
 

I will admit to being lazy. I want to do the least amount of work as possible (I worked 75 hours / week for over 45 years)… if I see some fuzz on the needle I’ll use my KAIU Anti-Static Turntable Stylus Gel Cleaner. I use as infrequently as possible. Don’t really notice a difference before and after. I used to use Last, never lost a needle.

I had custom acrylic dustcovers made for my 2 turntables to keep dust out. But I can't use them when playing. 

I used to use a brush with Last with dry brushing first. Then got the Orzo and I won't risk stylus damage with my new cartridges.  So I am now lost as to what is the definitive best cleaner.

And now Fremer says you have to use a carbon fiber static brush like the AudioQuest or Clearaudio etc. But why if you use a Loricraft or Ultrasonic before every record is played. 

I need to find the consensus!

+1 mrskeptic. Great moniker 

I have been against the use of solid cleaners from the beginning. Almost all if not all of the best styli are glued on and even if your motion was perfectly down and up you still risk tearing your stylus off. The residue problem was an unsuspected problem that is unacceptable in any amount. The residue gets deep into the grooves, dust sticks to it and you have a real mess. 

I have seen many very poorly kept "audiophile" systems so it does not surprise me that the problem went undetected for so long. Most people do not routinely check their styli under magnification. Wally Tools is expert at looking at styli and I would take their warning seriously. If they are wrong Onzo will sue their asses off.

I use the Lyra Stylus cleaner which comes with a nice soft brush. I use to use an artist's brush with 50% IPA but I was told this might attack the glue and cause failure eventually. I clean my stylus every month or two maybe. Using a conductive sweep arm and a dustcover effectively keeps dust from getting to the stylus. I have a look once and a while with a USB microscope to make sure nothing is forming on the stylus. Large clumps of dust are obvious. 

I ordered a Flux Hifi ultrasonic stylus cleaner yesterday. Been meaning to do so for awhile. Won't throw my DS Audio pad away just yet.

Those pictures are pretty meaningless without some context. First of all, was this after 1 cleaning? 10? 1500? Were there other substances used in addition to the Onzow? How clean is the area around the turntable? Lots of other factors could be at play, but if Mikie says it's bad, by all means stop immediately. 😐

@mulveling exactly…the DS certainly does not seem to contact the cantilever…

@jerryg123 ya man, strange how it took Japan Inc to relearn us our own tools. I actually prefer fishbone diagram. My team knew to show up without one was perilous… eventually they marked my parking spot with…..a fishbone….

My Lyra dealer sold me the Stylast, he moves a lot of both….for now i feel safe…

best

Jim

Dang guys, don't throw your DS Audios and Onzows in the trash just yet.

@vinylshadow @jpjones3318 posted this.

I use a method that was approved by Peter Lederman, or so I was told. Blue Tak, I put it on an old credit card and simply lower the stylus onto it. Then every few plays I use the MoFi LP9.My Onzow was too high to fit the cart onto. Hope this helps, respect.

So what IS the best stylus cleaner? 

I've got a new Benz LP-S and Miyajima Zero about to be mounted so I'm perplexed.

I have a Zero Dust but that goes in the bin now. Record brush? NG it seems. 

@tomic601 I am sure this will all come out in the wash (yep I said it).

Engineering 101 Ishikawa or as we call herring bone diagram. At Cooper Industries it was a diagnostic Tree. Tomato....

I use the DS Audio, stylast frequently, and every now and then AT liquid / brush. I never had much luck w magic eraser or blue tac…

Having said that with 30+ years experience in tech, there is no way i would publish that photo without some form of comparison to a control ( see design of experiments, ishikawa diagram, etc… ) if as asserted by Wally that the residue presents in 8 hours, it’s just not that difficult to build a slam duck root cause case…..or not…..

@daveyf Like we say here in CHi Town, Not only No but F NO.

Why would I post Part Due.

Your not Millercarbons son are you?

@daveyf I concur.

@jerryg123 it it is very strange….

a strange coincidence….with regards to Wally tools.

You aren’t connected to them…or are you?

Interesting information from Analog Planet on Stylus Cleaner Onzow Zero Dust.

@terry9  or perhaps none of the above, and none of them heard any degradation at all. ..:0)

@daveyf 

Alas, we have no idea how many of them perceived something but did nothing about it. Perhaps they had no access to a good lab, Perhaps they put it down to stylus wear.

stop using mine years ago you could hear the sound degrading 

@terry9 There are many folk here who have used Zerodust for years, do you seriously think that none of them would have noticed major build up of goop by now that someone would have heard a difference in SQ???

"I am sure that is what started the investigation...."

How would you know this???
