What's simplest effective record cleaning process

Dust them with anything that leaves no residue before you play. I use a dry Discwasher to pick up the loose & hairy bits. Spin the disc, rotate the brush during contact, wipe the brush in the opposite direction on your jeans - viola; clean record, clean brush! For stubborn chunks, dislodge the offending meteorite with a plastic guitar pick. Back in the heyday, a friend of mine cleaned only AFTER every play, the idea being his LP's were always ready for immediate service. But then again he also never owned a bed 'cause he was a stoic outdoorsman and preferred a sleeping bag surrounded by stacks of national geographic atop the wall to wall carpet. It takes all kinds :^)

The Decca or Hunt carbon fiber brushes are about the best thing I have found for dusting, without building up static. Without washing, dusting is all you can do. Do it just before, and maybe after play. If you handle your records carefully, to keep the fingerprints off, and you don't buy used albums, then the brush will be satisfactory. You won't get quite as quiet of a sound as you would with washing, but it will be good.

Buy a used VPI 16.5 record cleaning machine. A few drops of fluid and one quick vacuum pass on each side and your LP sounds new. Well, unless it is scratched or gouged, of course!

A carbon fiber brush is the minimum time/fuss.
