"For a few hundred bucks more, even less on the used market, get a vacuum machine system but something that does NOT have the record(s) bottom sides on a flat surface while you’re cleaning the top side. The last thing you want to do is clean one side and then flip it over and put it on a contaminated flat surface while you clean the other. What’s the sense in that?"
I purchased an inexpensive rubber TT mat for my Okki Nokki to use when flipping the clean side down.
