Back in the day, I had two small rectangular, metal tubs made for me by a friend. I’d fill it with warm tap water and a bit of rubbing alcohol and 3-4 drops of dish soap. I had some dowels and put a record on the dowel and insert it into the tub and spin it around for a few minutes. Then I’d put the record, still on the dowel into the second tank that was filled with distilled water and spin it for a few minutes. Afterwards I’d put everything between a couple of books, give it a
spin or two and then let it air dry.
