Walker Audio Prelude gets my vote. Despite the fact that I use a thread based RCM, and the Walker product is a four step process (making for 8 passes per LP), the results are worth it. My LP collection is large and has a very high sentimental as well as intrinsic value. The results are well worth the time and effort. Once a record has been cleaned with all 4 steps, it is only a matter of the occasional step 4 rinse to keep them at their best. I also use the Walker Talisman before each spin.
