In the welding trade- certain "stick" welding rods by AWS code are hydroscopic- the flux absorbs ambient water in the air in humid conditions-- so we keep those rods in dryer ovens- in my shop, I have an old Philco fridge (thanks, Grandma) with the racks and a 150 watt light bulb- compressor remover--works like a charm-- ditto my Browning 32 gun capacity "steel tomb" I use the large Golden Rod, and also have the safe up on treated 2x6 framing- as putting a steel safe on a bare cement floor is not the best way to inside air flow around the periphery--
I knew what you meant Fox, even if the spelling was a bit off.
