I have a mixture of brands of screwdrivers, all in an open toolbox in my attached unheated garage. Only 2 of my Craftsman and 1 Fuller collect a white mildew though they are next to other screwdrivers. I wash them off, scrub them, hand wire brush them, wash them again, spray diluted bleach on them, let then dry, and the mildew comes back.
Anyone have this problem?
