Those seem pretty nice. I might pick up one of those soon.
I've never really had a problem with the rust in CO, until this year. I'll admit though... I'm pretty bad about cleaning them.

I really like the color indicator on the silica or whatever it is, if only because that lets me judge how much moisture is getting into the safe. Had the safe in the garage for a while and I wondered if the hot/cool temperature swings would cause a moisture problem, but it was showing that it really wasn't getting much moisture at all. At least until this year, have probably charged mine at least twice this summer when it went months if not a year most of the time because it's so dry out here.
Our gauge indicates an average of 45 - 51% RH this summer, seems a little high. Having a whole house humidifier i turned the RH adjustment till it came on, @ 45% Another year of rain later in the season doesn't help . I use that crystal kitty litter for moisture control in the safes
I picked up a product from Home Depot called DampRid, it comes in about a quart sized container with crystal absorbent material for under $3.00. I had it in the safe for the last six months and had no signs of rust or dampness. I went moving stuff around yesterday and the canister was sloshing with water. This stuff actually absorbs and TRAPS the water in a reservoir below the crystals, there was well over a cup in there!
Picked up a refill pack (good for 4 refills) for under $4.00 and its back in place doing its job. As mentioned before, evaporative cooler probably contributed a lot.
Anyone else use this stuff? I'm real impressed with it.
I've never had a problem. I get to see my guns every 6 months and have never sen a speck of rust.
Basements are typically more humid. And being very close to the lake doesn't help either.
Apparently that stuff is acidic. SHouldn't be a problem if you don't spill it everywhere.
I have two of what Opie linked to. They are pretty good. They are easy to recharge because you just plug them in for a few hours. So I have two in my executive safe where I keep my Obama phones and I have it timed where one will need recharging before the other is done.
