At this point, clean records are the next thing to focus on. As Lugnut pointed out, a vauum-based machine would be great. If the cost bothers you, you can start doing them by hand w/disc doctor brushes. I highly recommend the Audio Intelligent Vinyl Solutions fluids. Buy a new dish rack at Target for $1.99, and a couple nice cotton bath towels to cover your table, and you're set. Clean the LPs w/the fluid and brushes, air dry in the dish rack. Put the clean LPs directly into new sleeves. Check the archives, there's tons of posts on details of cleaning regimens. Cheers,
