Mild Ivory soap with 2-3 drops of Dawn dish soap, painters cut in corner brush, Luke warm water, round & round we go with sudsy painters corner tool, the little fibers do get the grooves well. Rinse with luke warm water, turn on the faucet so there is no aeration in the water, just a steady water stream, so the water gets in the grooves. Lay flat on,clean,cotton,dish towel, gently press down, hit the basement, where I turn on my industrial shop-vac, which I lined the small attachment with sticky felt pads which I cut to go all around the surface of the attachment, slowly seal the suction to the LP, WHILE TURNING IN A SLOW circle to suck out all the water , until they are dry, place on dish rack with a dyson fan blowing on them, wipe with an anti static gently wetted cloth, wait 3 min, then into a discwasher or MOFI, single,sided,rice paper inner, then put the jacket in the Japanese Mylar re-sealable bags,….seal, put away. Most I do play through to check for pops and ticks during playback.
Works a charm, mild ivory soap,and a few,drops of Dawn for fingerprints,or whatever is there.
We buy a lot of used records, so most are dusty and fingered up with skin oils.
Works great for our small Box of records.
