By far the best groove cleaning machines regardless of water as long as it is distilled once without any other issue and clean works miracles I am referring to the Monks type RCMs.
The second best is the sacrifice a cheap cartridge stylus method. Run the record with the no sound on a cheap TT. Use an eliptical cartridge AT makes some cheap ones outfitted with a good "needle". The stylus goes into the groove of course and grabs the schmutz as Corona says. Unfortunately once is not enough. Do it three times, then finish with a velvet brush and any cleaning solution and rinse you have. I am not kidding, you are saying that the record is damaged using this method. I argue not so brother.
