I make my own strong mix, and vigorously scrub only once, use the manual spinner machine for distilled water rinse only, air dry in the rack. Batch of 10 while listening from a closer than typical position, amazing imaging.
it makes a huge difference to old dirty LPs.
.
after than, I keep them clean, and just remove any paper lint ...... off the surface, I have a drawer full of inner sleeves I bought, I probably should use them instead of the old paper ones.
Friday, listening with a friend, I just heard some clicks and pops on a Cassandra Wilson double LP I bought new, maybe average two per track, previously played a few times, it’s winter/less humid now, I’m gonna clean it and see if the clicks and pops go away. Put in new sleeves, see if it stays quiet.
