Ultrasonic record cleaners

@charliee Evidently I was less clear than I hoped.

I was describing a test procedure. My cleaning procedure is:

1. wet and remove surface crud with running purified water

2. for very dirty records only, 10 minutes at 37 KHZ with detergent; otherwise skip this step

3. 10 minutes at 80KHz with detergent and 40 degrees C

4. rinse heartily with running purified water

5. rinse in distilled water bath

6. spritz with distilled water

7. air dry

Amongst the suggestions Neil makes for an LP cleaning process/procedure, my favorite new step is to pre-rinse the LP in the sink. I bought an item on ebay to facilitate that rinse: a product comprised of a pair of LP label-size clear plastic discs, with a handle to hold the LP under running tap water (at this stage of cleaning---and this stage only---tap water will suffice).

I use this step only for used LP’s (or unusually dirty new ones), to remove the dust and other debris often found on those discs. That prevents the dust and other debris from contaminating both the water in my ultrasonic tank, and the platter and brushes on my VPI HW-17.

I also have found Neil’s recommendation of Tergitol 15-S-9 (the surfactant made by Talas) and Liquinox (the cleaning solution made by Alconox) to be an excellent one.

For the final step, I don't care for or approve of "air" drying. Though I'm no longer in the California desert (dust is EVERYWHERE there!), I still prefer to vacuum off the final rinse distilled water. Two revolutions on the HW-17 gets LP's bone dry, usually without creating a static charge. For that problem I have and highly recommend the Furutech Destat III. More effective than the Zerostat, and far easier to use.

Cleaned my record collection using a VPI and the Walker Four Step Process. 90% thru discovered that no one does the Fourth Step except maybe Mr. Walker. Sigh.

Re cleaned VTL 006 The Doctor with an Audio Desk machine. Played Isn’t She Lovely.

Way more natural. Less hi fi. Cymbals are relaxed where before they were etchy.

Prolly you want to know the rig. Lyra Atlas Sierra Lima. Basis arm and turntable. Super Lumi phono stage. Nagra pre. Manley 440 w/KT 77 driving Eminent Technology Super Eight mid/tweet. Manley 500 w/KT 90 driving woofers. Hsu VTF-2 Subs. NBS wire.

So called damaged records are mostly dirty. Clean ’em up and they’ll sound great again.

Important to use Stylast 4 and 5. 4 to clean yr styus after which use 5 so’s the stylus will slip thru the groove. It’ll sound better and preserve yr stylus.

I lean toward the idea, a Clean LP with certain sized contaminants removed from the Groove will be an improved environment to allow a Styli to have an extended usage life.

A cartridge styli is one of many parts that are impacted on by contamination.

The Crud that collects at the Armature Base at the Damper and Coils interface is quite something, it is a hard to believe the collection of particulates when seen.

A not too old Cartridge with not too many hours of usage can easily be in a state of cleanliness that will be a condition that will most likely impede the Cart's performance. 

I am even aware of Metal Dust Particles entering the body to come into contact with the Coils and ultimately burning/shorting out a channel.

The cleanliness of the LP Groove is only one area of cleanliness to show a concern for if the very best replay is the ambition, if the longevity of the Styli is the only concern, then the Groove being clean, seems to be a good measure to assist with achieving this, it certainly produces a valuable 'peace of mind'. 

@tennisdoc56 +1 on the HumminGuru recommendation.  I too was interested in an ultrasonic cleaner but didn't want to spend $3,000 on a Degritter or KL Audio.  All ultrasonic cleaners basically do the same thing, spin a record in a bath of water, have a set of transducers to shake the dirt loose and then dry the record, Many have mentioned that the HumminGuru's transducers are not as strong as KL Audio or Degritter.  HumminGuru's transducers run at 40k Hz and DeGritter operate at 120k Hz. I can't comment on which is better and by how much.  There are many YouTube videos on this topic.

None are miracle workers and won't repair a record with medium to heavy scratches and if a record has lots of dirt or grit, you should first clean the record via a suitable brush before using any ultrasonic cleaner..

I decided to purchase a HumminGuru for $450 and am happy I did so.  The HumminGuru is simple to use and I find it cleans records better than a vacuum based cleaner.

For any ultrasonic cleaner, you'll want to use a surfactant such as GrooveWasher G-Sonic concentrate to break the surface tension of the distilled water used in the cleaners bath tank.  For the HumminGuru bath tank, 1 drop is all that's needed, so a $30 1 oz bottle should last a lifetime.  

Remember to use an anti-static device as static noise can be as bad as a dirty record.  I still use my 45 year old ZeroStat device with terrific results.  Make sure to test it's effectiveness with the supplied mini light bulb which is basically a Christmas tree light.

Hope it works out for you.
