Camphor Blocks in the tool boxes and tool drawers.
My grandfather and my father always used them and that’s what I use, since it worked so well for them. Your shop will smell a little like moth balls but that helps control the spiders and bugs from entering. ;-)

I get them from our local pharmacy, or you can order them from Amazon.

For cast iron table tops use your favorite auto ‘paste’ wax, the same way as you would on your automobile, just be sure it contains NO silicone products.
