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.

I don't take enough pills to do the same, but Amazon lists 50 packets of silicagel dessicant for $17. https://www.amazon.com/10g-Silica-G...137&sr=8-1-fkmr0&keywords=silicajel+dessicant

Betcha a buck with a little searching you could find it in larger quantities and cheaper. Lots of tools and gadgets would benefit from desiccant use. Planes, scrapers and chisels come to mind.

You can dry it out in an oven to renew it. I have some 1/8 inch desiccant balls in a jar to keep my hearing aids dry. There are some blue ones in there that gradually turn white. A minute in the microwave and they turn blue again.

Here's the Amazon link to bulk quantities of the stuff. https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias=industrial&field-keywords=dessicant

I've been doing this for a while now... both the dessicant my wife gets in her scripts, and whenever we get one in a package we receive. Toss them in my tool cabinet and so far, no rusty tools.

Look for silica gel in bulk used to dry flowers. The blue crystals are indicators and turn pink to indicate the need for the oven refresh. 200° should do it. It will never wear out.
If you have a camera store nearby, they will have packets to give away. The packets get included in items shipped to them.

If you load the bulk beads into "bean bags", make the bags out of cotton or light canvas. You don't want to put acrylic fabrics in a hot oven. We're bone dry out in the Mojave Desert, so rust isn't a problem, but for folks in muggy country, I think this stuff renders serious help.'

Just thinking about being able to see the color change that indicates it needs refreshing. What about putting the stuff into bottles and making holes in the top? You can save or get bottles in all sizes. When I used to go to big meetings, they'd have small, 2oz jars of jams and jellies. I copped a dozen or so of them and they'd be perfect for this task. I pour the beads onto a plate to dry them out in the microwave. Those small jars are pretty tough and are unlikely to break with heat or even rough handling.

Or you could get 2 oz Mason jars https://www.amazon.com/Mason-Jar-Ou...523&sr=8-5&keywords=2+oz+glass+jars+with+lids

For larger iron tables or rust prone steel, you can't beat this stuff: https://www.amazon.com/Boeshield-RF...pID=41t4azFU8uL&preST=_SY300_QL70_&dpSrc=srch
