Silica gel can also be rejuvenated. Place it in the microwave and give it a 30-second shot. Let it cool and do it again two or three times. It will get HOT and can melt, which I think isn’t good, but it can be dried out and reused.

The material is silica gel (it’s actually granules like salt). We used to call it “silica gel – do not eat” because that is what is printed on EVERY packet of the stuff.
I bought a big can of silica gel at Wal-Mart in the craft section. It is used for drying flowers. Very cheap.
I poured some silica gel into the bottom of a mason jar, and I keep my bottle of Loctite ACC in there. The ACC has stayed good throughout my glacially slow build of the UP S-40-10 stock car that was the subject of Shake-N-Take many years ago.
P.S. I live in a part of California with low humidity.

This had me thinking of those decoration and functional canning jars or kitchen containers that use a thick rubber seal and a clamp on glass top.
That should work as well as a non vacuum desiccator with the same stuff inside and cost near $5 instead.
I save all those little packets that come in almost everything you buy. While I don't know what chemical is in them they all say they are a desiccator of some kind. They are free.
