I'll vouch for the DIY RCM. I built mine a few years ago (there's a picture under my system) with the intent of one day buying a really good. I still have my $50 plywood/Hoover RCM but I still say that someday I'll spring for a Loricraft or Monk. Kurt_tank is right on. Mine is noisy and somewhat labor intensive, but it does a really good job. Like DougDeacon posted, the vaccuming really makes a difference and you can get good results with a small shop vac that has good suction. But don't discount the work that a good brush does, such as the Audioquest and the Mobile Fidelity. I'm also a believer in RRL and AIVS cleaning solutions.
Best Temporary Record Cleaning Options
I have a new TT on order and need to line up some record cleaning options. This is my first TT since 20+ years ago when I used a discwasher on an old technics table. I will be slowly buildiing a vinyl collection from both new and used sources. I am not going to be able to throw down for an automatic for a while so I need a fiarly good temporary product that will help me get and keep records in great shape. In my search of the archives there is some amazingly in-depth content about record cleaning solutions and automatic machines but I can't seem to locate info on what the best options are for brushes, kits, etc.
