Forgive me if this has been addressed before, but what would you recommend for a vinyl collector (or 78 collector) who wants to clean some especially dirty discs? Has anyone tried the products from Disc Doctor (http://discdoc.com). I am speaking about private collectors (not an institution) who have limited finances.
