@antinn Thanks ... I think ... for turning me on to that post by Wizzard. I suffered through nearly all of it. That man is in need of help! The Arizona Mike tip, however, was considerably more helpful! The video afforded a good real-life look and sense of the operational footprint the KLAudio requires, much more informative than photos of the machine on the web.
I tend to do record cleaning in spurts. My modus operandi has involved setting up the Knosti on the kitchen counter and shuttling records to & from my US machine, set-up on a work bench in the basement. After an afternoon's activity, generally 15 records worth, I break down, clean and put everything away until the next foray. I don't save or re-use cleaning fluids or leave same in the respective vessels.
The KLAudio certainly seems like a fantastic bespoke US record cleaning machine. However, given its size and operational footprint, seems like it's better suited to a more industrial approach (i.e. more sustained, lengthier cleaning sessions). It's easy to see how critical such a machine would be for an operation like Arizona Mike's record shop and record cleaning service.
I continue to struggle with more practical, cost-effective alternatives for my purposes and am considering the following, which would involve purchasing an Elma Sonic P60H, another Knosti, a vacuum machine or combination thereof. As always, your comments & suggestions would be most welcome.
- Solution of distilled water + 0.01% or 0.015% Tergitol 15-S-9 + 1% Alconox Liquinox in the Knosti as a pre-cleaning step.
- Use of the Elma Sonic P60H with distilled water + 0.01% to 0.15% Tergitol 15-S-9.
- After degassing, run 2 or 3 records (2 would achieve a 1.25" separation; 3 would be 11/16") set to run between 31C and 35C but no warmer than 35C at ? RPM for ? minute cycles. (Questions here are: how many records would be best, 2 or 3, at what RPM and duration of cleaning cycles? I've read that keeping the cleaning temperature between 31C and 35C for no more than 6- to 9-minute cleaning cycles is optimum in a machine like the P60H and anything longer could cause damage.)
- I'm not sure how to approach an immediate final rinse with distilled water. I'm thinking of transferring the records immediately over to my present 40kHz US machine for this. However, I'd have the same questions here regarding heat setting, spacing, RPM or, more importantly, the advisability of this at all. If lengthier than 6-to-9-minute cleaning cycle in a P60H is not advisable, maybe exposing the records to additional US bombardment is not a good idea? Maybe it would be best to purchase another Knosti for this?
- This leaves the drying dilemma. Records would be sopping wet after a final rinse in a Knosti, making air drying in a rack and use of microfiber cloths less appealing. A vacuum machine would help but this approach would involve purchasing another Knosti and a good reasonably priced vacuum machine. This puts a dent in the cost-effectiveness quotient; not to mention making the whole cleaning process seem like an episode of the Keystone Cops! Previously, my approach was to raise the records out of the US tank fluid and run them on the spit or skewer at 5 RPM for 15 minutes. Not only did this allow the tank fluid to cool but the heat rising above the tank served to dry the records almost completely. After this, I sandwiched the records between LP-sized microfiber cloths to remove whatever drops of residual moisture might be left and stave off dust motes, transferred them to the Knosti drying rack and covered them with microfiber cloths until they were completely dry.
