    Taking care of your desiccants

    Sounded dirty, didn't it?

    Just a reminder not to forget the desiccants you may have in your gun safes, ammo cans etc. On my list of chit to do today, I gathered all mine up and am rotating through the oven to 'recharge' them. So if yours can be recharged, this might be a good time of year to do so as many folks are taking an extended holiday break. If they can't be recharged, then perhaps it's time to replace them.

    My audiologist recommend I keep my hearing aids in a container at night with desiccant bags.
    She said about 5 seconds in a microwave on occasion will dry out the desiccant.
    I don’t know how true this is.

    If you have a seldom used firearm , put desiccant in a bag w/gun, and vacuum seal both. Make sure it's clean and ready to go when unpacked. Put a pack of sealed ammo handy too.

    5 seconds would not be enough time for the water to boil out.
    I found an article that said 3 - 5 minutes would work.

    Some desiccants, calcium sulfate (Ca2SO4) have indicators to tell when wet. Usually a cobalt (II) chloride included (CoCl2 . XH2O), which is blue dry, pink when moist/wet/hydrated. Other good desiccants are sodium sulfate, magnesium sulfate. You can use same indicator ( CoCl2) or CaSO4 infused with CoCl2

    If you put any of those in an oven when the color changes back to blue it's useful again. No need to throw away or buy more.

    They sell CaSO4 as drierite cheap. Get the stuff without indicator as bulk, then cut it with the CoCl2/blue stuff to see when it gets wet/moist. That is put a little of the blue stuff into what you are storing, if it turns pink it's wet. The blue CoCl2 infused stuff is much more expensive.

    I hope this is helpful?

    I got lazy. Have ones you take out when they turn pink plug in 12 to 24 hours depending on size put them back.

    I was lucky enough to salvage dozens of multiple sizes of dessicant packs from work before retiring. I use my dehydrator
    to "recharge" or dry out my used dessicant bags. My biggest problem was coming to realize that ziplock bags leak moisture
    into the bag like a seive. Now, all recharged bags go in a mason jar.
    BTW, the blue chemical indicator on silicone dessicant is poisonous, the plain silicone dessicant is harmless.
    I really want one of these!Hidden Content

    You can make your own dessicant packs using 100% silica type cat litter and coffee filters. Cut the coffee filters to the size you need and fold in the cat litter and staple shut. Much cheaper than buying dessicant packs. I use them to store matches and it works great.
