CleanerVinyl Ultrasonic record cleaning system.

Rushton, I have seen your formula and seems very reasonable and am planning on using it. The reason I asked about the TergiKleen is that it was posted after your post on your formula and wanted your opinion. 
I fully understand, not overloading the the cleaner and the 1 inch separation.  When cleaning 2-4 records at a time do you feel the inner sides and the inner records get as clean as the outer side of these records or better to just clean one record at a time?

I clean 4 records at a time in my 10L tank spaced 1" apart and the inner sides and inner records are just as well cleaned as with just a single record in the tank.

Have been using a 10L tank and hand turning the records on a homemade spindle, but only as a rinse with distilled water. 
Using AI products, somewhat highly concentrated "Down with Dirty" followed by #15. I allow each to sit on the record surface 3-5 minutes, maybe light scrubbing rinse with pretty warm tap water and then rotate in the ultrasonic with the distilled. Keeps the grunge out of my tank and removes the minerals from the tap water. 
It just seems pretty expensive to load the tank with fresh solution and contaminate it with dirty record product, only to drain and repeat. 

BTW, thanks for the heads up on this. Just purchased one on Ebay..

KL Audio machine is much quicker and works much better not cheap though.

I agree with you completely about the seeming waste of loading an entire tank up with chemicals only to drain and throw away the solution after just a record or two. In my set up, I use an inline 1 micron water filter and pump so I can recycle the water in the tank through the filter. I turn on the pump in between batches of records and only change the tank solution every 30-50 records (depending on how dirty the records were).

I took the idea for the pump and filter from bbftx on the diyAudio forum. Here’s his short video showing his implementation and a link to his description and parts list...

The inline water pump bbftx uses in his setup has been discontinued, but I found on as new old stock on ebay for $50. There are others that will work.
