Do you clean your records before play, after play, or once (and then never again)?

thats when I bought VPI-16.5, after reading this:

@bradf - you might look at Rushton’s thread here, which is based on an article he wrote for Positive Feedback. There is a relationship among size of bath, number and power of transducers, frequency, etc. viz surface area of records to be cleaned. (Sorry, I don’t remember the formula--it is buried in the long thread on DIY Audio about ultrasonic cleaning). @terry9 can speak to his experiments with the number of LPs in the bath v. cleaning effectiveness.
The bonus to DIY isn’t just cost-effectiveness either. You can take advantage of higher frequencies, heat control and other features that aren’t necessarily offered on the audiophile machines.

@whart  -Thanks for the info. I will go over content contained in  reference  to Rushtons and terry9 threads

I just got an Okki Nokki for Christmas. Since receiving the unit, I clean every record before playing it. I use a homemade cleaner made with distilled water, IPA, Triton X 100 and Kodak Photo Flo.  I rinse with distilled water having a little Photo Flo in it as well.

I have used 'The Last Factory" record cleaning and treatment for products and have found they work as described. I wouldn't be without them.
