Tergikleen or AIVS formula 15?

It looks like Elusive Disc sells the Walker cleaning products. The Enzymes are priced reasonably.

@traudio, I was at a friend’s house using his equipment. He has the latest fluid Degritter offers created by a scientist. He has a second tank, we just didn’t use it. I was using a hand held steamer to clean any brushes between lp sides. Don’t know if Walker is still in business. What I like about the enzymes is you can make up a small amount to compliment how many records you are cleaning.

Slaw,

What fluid do you have in the degritter? 

I have the second tank so I can use the rinse feature. You might want to get one for your final rinse, it's very convenient. 

Got a link for Walker?

I used and liked AI products for years. Deep cleaned some records recently using Walker enzymes, then Pro-Ject vcm, then a rinse, then into a Degritter II, then a final rinse on a Project. Noticeably quieter surface noise.

I would but formula 15 is not a concentrate. It would take the entire bottle plus some. 

In the Degritter I've tried the new version of the fluid that ships with it, but the AI concentrate that's made for US cleaners works better. After that, I have a second tank for the rinse with just distilled water.

ENZYMATIC RECORD CLEANING CONCENTRATE FOR ULTRASONIC RECORD CLEANING MACHINES

Have your tried the Ai fluid in the spinclean?

You need to do a side/side comparison. That is hard to do, can you manually clean one side with X and the other side with Y then listen? 

With your Degritter after, not sure the pre-clean is as important. Do you use anything in your Degritter? that also make a huge difference.

I would just do what is most convenient for you. My cleaning is also a 2-3 step process, with a manual clean before UC. If it's really dirty, will do both steps twice. 

Interesting. I'm not sure what purpose having an old and new brush serves, other than needing to buy brushes less often. 
I also give them new sleeves and a sticker with the date & fluids used. It's the Engineer in my bleeding over to civilian life 
I used to use a method similar to yours with the Spin Clean and Disk Dr. It's not bad for the money invested, but now I prefer not to have the record touching the lips of a vacuum machine after it's clean. Possibility of recontamination bothers me. 

My set up is similar but without an ultrasound. Over the past 50 years I have gone to the less chemicals that touch my vinyl the better. I use Tergikleen (20 drops per gallon) (or Photoflow) in a SpinMaster, too. Whenever I buy New brushes for the SpinKleen I reserve one. I use a "new" brush and and older brush, and flip the record halfway through my process (anywhere between 12 full revolutions- and whatever might be needed. I rotate in both directions). I rinse with distilled water from the grocery store over the kitchen sink using a pressurized spray bottle. I dry/ final clean on a Record Dr., once again, rotating both directions, maybe a total of six to 10 rotations per side, and finish air drying with a bamboo dish rack. I pre-clean with a shaving brush, and use a Zerostat for obviously charged records. New inner sleeve and a quick note on the little yellow sticky with date cleaned, condition, whatever. New outer sleeve, if needed, and then back into the rotation. I don't think that there's anything more personal in our world than our record cleaning technique. Maybe stylus care comes close. My changes now are incremental, maybe a new style of label protectors, different "examination", or curator's gloves. Maybe I should start a Go Fund Me for a Degritter...I would only mention what I do, and never tell what I think you should do. It's a journey, not an assignment.

I'm not a record collector, my real hobby is cleaning records   ;)

"2 Spin Cleans AND a Degritter?"

Yeah, I got the 2nd one for around $40, brand new. couldn't pass it up. It's handy to have it for a rinse which opens up more methods to try. 
I've always used a Spin Clean for new (to me) record that I get used. 

2 Spin Cleans AND a Degritter? 

You must be a bin diver, finding those grungy, undesirable gems? I do the same thing, except pass on those that would warrant such effort.

 A drop in the Degritter and be done with it, is what I would expect. 

Been using a Spin Clean for 15 years or so, while procrastinating purchase of a proper US. Still waiting for the 1/2 off, fire sale of a DG/Audiodesk... Good thing I'm not holding my breath!

Your setup appears to a perfect excuse to lose track of time and accomplish nothing else in the day-not that it's a bad thing!

Possibly, but I think a second cleaning would obscure the results wouldn't it?

I could try this with a double album assuming both disks were equally dirty.
