Bringin' that thrift-store smell home

For the past few months I've been avidly (my friends say compulsively) searching the local thrift stores for LPs. I've found some great recordings, but as I accumulate more and more of them I'm finding that my house is smelling more and more like a thrift store. I expect that many of the LPs I've bought have been stored in damp places and have become moldy, even though they look fine.

Has anyone else faced this problem? Any ideas for deodorizing LP jackets? Thanks.
