for ammo cans?

Do you guys put it in your USGI ammo cans?

I usually keep some in my range bags and gun cases, as well as in ammo storage.

I've found it at camping/backpacking stores, or fishing outlets as well

I used to keep ammo in the house, but my wife made me take it to the garage.

send me a link, what kind, size bags, etc that you use please.
At hobby stores you can find silica gel in gallon paint size cans for drying flowers.

Kitty Litter BLUE CRYSTALS. Can't remember brand name. Bag it inside empty unused tea bags. Used it successfully for years.

Same thing here.
There are a couple of types available.
I used paper coffee filters & hot glued them together / closed.

I got my packs off of Amazon, I put them in ammo cans and also seal one in with M14 parts I put in 4 mil ziplok type parts bags. It's cheap enough to get the real thing.

Roll your own. Buy once, and let us know when you've run out.

Doing it this way is roughly 3x the cost for 100 bags as opposed to buying the ones I posted, any benefits that good to justify the extra expense from doing your own?
I know the bags would be bigger but a 4" x 6" bag isn't needed for an ammo can unless you've got a 20mm lol.

Do you put one bag per can?
How long will they last?
I've commented on this before but...

I discard desiccant packs when I see them and threw away all plugin dehumidifiers years ago. I live on the Gulf coast in central Florida and it doesn't get much more humid than here. All my 30 and 50 cal ammo cans are stored in a non-climate controlled garage along with half my gun collection stored in safes.

Been using these for a number of years for the safe with zero rust or corrosion issues. Replace annually; just write the date of install when they go in and replace when needed. I use two even though, based on the square footage of my safe interior, manufacturer says one should be sufficient.


Ammo cans get one of these stuck to the inside of the lid each year. Again, zero issues with rust or corrosion.


VCI technology has been around for years, and IIRC, is used today in shipping containers during oceanic crossings. Some manufacturers sell VCI bags sized for rifle and pistol storage. Can even buy VCI impregnated "paper" for wrapping odd-shaped items.

For whatever you want.

You can also use it for other purposes, like drying out things you didn't want to get wet, whatever. It'll also fill more than 100 bags, and you don't need to make the bags full to have them work really well in an ammo can. You can tell when they've absorbed moisture and you might want to refresh them, because they turn from bright orange to blue, and it's also easy to 'recharge' by throwing them in the oven, and you know they're fine because they turn blue again.

It's an option I went with, and I like it. It's certainly not the only right way to kill your cat.

There is a downside, though. After you've used whatever you need for whatever you need, you're wondering what you're going to do with half a large container of orange beads...

Maybe buy more ammo?

I suppose I could make party favors for my friends, if they'd ever come to my party.

Uline sells a 5gal pail of them.... ( split it up amongst friends. ) They can be "reactivated" ( dried back out )

I am a little OCD about using them, and tend to replace them after a month with a fresh one for long term storage.
Reason being , the first one will absorb the majority of the moisture in the can, and the next one won't be "moist" like the first one.

Seems to work well.

That is way cool, I never knew that, you can't tell with the commercial ones, thanks!

I'm in the desert so yeah I just put one per can, they usually come with some kind of guide for how many cubic inches it will treat. If I was at the coast or South I'd definitely double/triple up.

I honestly don't know any way to know when they are done, I just replace them every year or two. I like premade pieces, but I also like the color changing properties of the one that MuppetMeat4Me is using, that is pretty awesome.

Had a thought yesterday as I was looking for something in my classic Snap On toolbox . . . and noticed some impact sockets getting rust on them.

Would desiccant work in toolboxes? They are not sealed tight of course, so I was wondering.

Try some VCI plastic or paper, used as drawer liners.

I will buy the bags for rifles or handguns , cut them to fit. That stuff works.... even in VERY humid conditions.

Like it has been said, lot's of ways to skin a cat, this is what I do. 10 Gram re-usable, the cans are sealed so it's not like there is a constant source of moisture.

Little bags found with new shoes, and electronics often have at least one, sometimes more packed inside. I save them. Recharge in oven at 250F for six hours. Most are the size of a large postage stamp. Some as big as my hand. Why pay $'s just reuse what comes to hand.
