Tergikleen or AIVS formula 15?

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

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.

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?

@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.

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