Thumbs up for ultrasonic record cleaning

Amazing ultrasound!  I’ve rescued 40 year old records from unplayable to like new. 
And, in that I’ve just recently learned the effective way to use my Zerostat, I’m a happy vinyl lover to be sure. 

The bath formula offered by Rushton is very effective, much more so than plain distilled water —which is subject to surface tension problems at the vinyl surface. 

Btw. 40mhz, as most tanks in diy US setups are, results in a wavelength well under 1/2 inch. Mounting records at 1 inch spacing is plenty.  Also it’s important to remember that some of the debris is loosened by the resonant US movement of the vinyl not just the fluid. 

Happy listening, all.

Despite being submerged, vinyl rejects pure water. Particularly deep in the grooves.  Hence the Library of Congress reccommending surfactant in record cleaning formulas. 
And lots of audiophiles getting good results with a wee bit of Photoflo in the US baths.
does lead to a need for rinsing, but that’s advisable anyway.
