You're doing it wrong!They also have a motorised platter. I mean why even bother with an RCM is you’re spinning the platter by hand whilst trying to apply liquid brush it and then vac it off.
You put the record on the platter. You apply the fluid. You turn on the vaccuum and you slowly rotate the record 2-3 times. Done. Results are WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY better than the Spin Clean, which I bought and used on 20 records before deciding it was an absolute piece of trash and returned.
