I had a VPI 16.5 and a NittyGritty as similar vacuum machines to the OkkiNokki. They worked, and well enough to convince me there was something to cleaning as well as possible. So about 12 years ago I bought a Loricraft PRC4 and was very happy with the results. Even so, records were generally not perfectly silent. Since then, U/S cleaners have come along, and I now use the Loricraft and then a Degritter. The majority of my records are now silent with respect to surface noise now.
I use a homemade mixture of distilled water, L'Art du Son cleaner and isopropyl alcohol in the Loricraft, and Degritter's own surfactant in their machine. I do keep some AI Enzymatic formula for the Loricraft for visibly filthy never-before cleaned used records. Once cleaned, I use a Destat, which means any dust particles (I'm afraid I have a scaly skin rash!) can be blown off with a photographic Rocket Blower. I no longer use any form of carbon fibre brush or cloth. Essentially, nothing touches the record once cleaned except for air, the stylus and a new polythene-lined inner sleeve.
