My shop is currently in a very damp basement, even with a dehumidifier.
I recently bought a silica gel box (Cabelas,

)
I put this in a rubbermaid tub with the hand tools I really care about,
and it seems to work well. I haven't had it for a long time, and it
wouldn't help at all with the big power tools, but it might be
something to consider.
