Thumbs up for ultrasonic record cleaning

Yes, the Rushton thread. I copied exactly, his recommendations. I only have a different pump in my filtering system as his original one is no longer available. On the DIY Audio thread, he recommends another RV pump that I have. I just got all of these parts in house now for the filtering system and am planning on getting it up and running this weekend?

I do a 30 minute cycle with the heat setting @ 45C, with the Vinyl Stack set at 12volts.

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.

I have no doubt that technically speaking the above post is most likely correct regarding the effectiveness of (spacing). I just go by my ears. As we all know, this hobby is a lot of times based on one's personal, subjective, hearing.

Cheers!

At some point I'll try fluids/cleaners...I'm in no hurry.

I agree that ultrasonic helps, but there is a limit to how strong it should be. I had one that broke off some vinyl pieces.

I am now using the Audio Desk Pro that uses better parts than the first version. It works perfectly and shows no vibration damage as the cleaning water has no black particles. I love it because you put the record in and can leave and return later for a clean and dry record.

I’m not sure what you mean by "broke off some vinyl pieces"? Could you be more specific?

I can only assume by your post that you previously had an earlier version of the AD and now compare that one to the (PRO)? Did they change the khz cycling?

Yes, the "set it and leave " function of the AD is compelling but all of the benefits of a more manual option are more effective and much, much less expensive...and may I say more logical.
