Saw your section in new TOH - tool rust. My home has a field stone foundation so my basement is always damp. When I noticed my tool starting to rust I thought to put those small silica gel (desiccant) packages in all my tool boxes and drawers of my roller cabinets and it works, no more rust!!! Packages are free in electronics, shoes etc. and I store extras in Zip lock bags until I need them. Try it it works.
