I'll answer that for me: My kitchen sink. Yes, I'm careful to wash in sectors, tilting the LP such that the label stays dry. But it takes a solvent action to remove the schmutz of the ages, and I start with dish detergent (not soap) and a soft sponge (fully wetted before making gentle contact). If I keep the LP in its sleeve when not in use, and if I use anti-static sleeves that don't shed paper lint, I only have to clean them that deeply once.What cleaner do you use?
Usually, the first playing after that deep cleaning is to make a needledrop.
