Use Disc Doctor, http://discdoc.com/.
I've been committed user and fan of the VPI 17 for well over a decade and have used it to clean thousands of records. This past summer I had a chance to try the Disc Doctor cleaning process, and I was totally blown away by the significantly improved results with Disc Doctor. Now I use Disc Doctor and the VPI handles only the rinse and vacuum as I gradually work back through cleaning my record collection with DD. I never thought this is where I would end up on this topic; I wouldn't have believed the difference if I hadn't tried it.
