I use a Record Doctor with Mofi Superwash. The records sound about the same, but boy, do they shine!
Vinyl record cleaning
I watched a video of someone cleaning records in a dishwasher. I think it was a Maytag, I've heard they are very dependable. I have a lady Kenmore which was left behind when she moved out and took everything else. Anyone try this method? I will today, I have nothing better to do.
