For what it's worth, I too used RRL products in the past. For the last few years, I used "L'Art du Sond" cleaner and have found that to work much better than RRL, especially on lp's that need extra deep cleaning attention. I've saved some previously unplayable unplayable lp's with it. It requires a second wash with clean water after the first step but one should really be doing that anyway with any cleaning solution IMO.
