I bought the KA-RC1 (Kirmuss) on the cheap but soon grew tired of the process outlined in the manual and the Kirmuss surfactant leaves residue in the grooves. Gave up on the machine for a good while. Then realized I could just use the ultrasonic cleaning device with surfactant added directly to the US bath. I found a recipe online and concocted my own cleaning solution using Triton X-100 and 91% Iso.
Once the record was cleaned with KA-RC1, I rinsed it, twice, with pure distilled water and vacuum dried it with my Okki Nokki RCM. The results were very very good.
I have a very noisy Pink Floyd record. Tried cleaning it many times before (using both Kirmuss solution and Okki Nokki) but couldn’t get rid of the noise but the last clean did the trick. Not a single click, pop or crackle. I had to play the record twice to make my self believe that its the same noisy record.
Hope this helps.
