When I had a basement shop in PA, rust was the color of some of our sofa pillows. Then I moved to Florida. Those pillows were the good ol' days. Before the move, I wrapped each of my band saw blades in paper and put them in a large, clear plastic bag. One day after the move I unwrapped one of the blades and, sure enough, I found some rust on it. Not much but it sent me a message. I cleaned off all of the blades with some WD40 and everything came off. I re-wrapped them and put them back into the plastic bag but, with a difference. One of the pleasures of getting older is that your pharmacist knows you on sight. One of the medications that I take comes with 4 or 5 of those little desiccant canisters. When the pill bottle is empty I just dump the canisters into the plastic bag. I probably have over a dozen in there now and no rust on any of the blades. I consider them "free" rust inhibitors. As the title says, this is probably old new to most of you but it might be an idea for some of our newer members who live in humid climates.
