Thread: Safe Dehumidifier

Damp rid isn't really a nasty chemical, but it is a calcium and sodium salt. They release a small amount of trapped moisture, combined with salt which is really good at stopping mould, not ao good for gun safes.
Your dehumidifier is just silica gel with a fan in it, but they work really well, i also used to buy my silica gel on special at farmers, even though it comes in a pretty pink bag. Then i bought a truckload of it from one of my wholesalers.
I tried to sell silica gel packs on the forum for $10/ kg but only sold a couple, now i sell it on Trademe for $15/100grams and it sells flat out, go figure
