Does anyone use this in their gunsafe & if so are you pleased with the results & where did you buy it ?
Also have you ever used KROL oil for bore cleaning & as a rust preventative wipe down ? I live in PA & NJ the seasons are usually not too wet.
Thank you in advance for your time & help.

I have used it my safe for many years with great results. Lou

I dump about a dozen on the floor of the safe, and stick a few in the corners and on the shelves every spring. Don't let any actually touch any of your forearms. as they obviously collect moisture...

Do they work? Well, I never thought of a way to measure their absorbing power, but my safe is in the basement, and I live on an island and I have never experienced any rust on any of my guns.

Is it a cure all? I don't believe so. I start cleaning in early May and make sure all the guns are newly oiled before the humidity starts setting in by the end of June. I have a dehumidifier running most of the time (and confound it, my wife hangs the laundry in my loading room, but I don't have a very big house to spread out).

Anyway, short story long is do everything possible to protect those fine arms, and adding the desiccants is just added security.

Where they sell them? I'm sure a bunch of places. Do a search on your web.

You want to add a source of heat to your safe. Cause I'm a DIY there is a small light bulb in mine.

Even a 4W will get buy. I now use 15W and the Goldenrod thingy is more WW's.

What it does is to warm up the guns so when the door opens the moisture does not condense on them.

soup,

I live near Houston, Texas, about 40 miles from the Gulf of Mexico. Seems like most of the time the humidity is near 100%. I've had my gunsafe in my Garage for close to 10 years. It is an American Security 23 gun fire resistant safe. I use the quart size metal cannister in my safe. I recharge it by heating in the oven once a month. I have no problems with rust on the guns that I keep in the safe.
I also use Kroil. I love the stuff. I am not a chemist so I can't give you all kinds of technical reinforcement. However, I will volunteer the following:
I collect long guns. Have 50+ rifles in various configurations all over the house and garage. The best ones I keep in the safe. The others are on their own. For long term storage I spray them down with a product called Rust Prevent.
I typically keep two cans of Kroil. One in my truck and one in my garage. That way I always have some handy for lubricating stuck parts or wiping down a rifle. I try to shoot some every couple of weeks. I also go to my deer lease in the Texas hill country for three days once a month. I typically take several rifles. All of my guns get wiped down w/ Kroil after handling. Its a light fine oil and doesn't seem to affect the different finishes on my wood stocked rifles.
I also use it on rifles in other ways. First, on a new or used gun before I fire it, I take a bore brush and wrap a cotton patch around it that has been saturated in a JB bore paste and kroil mixture. I give it about 300 strokes through the bore. I figure that’s kind of like hand lapping. It shortens my barrel break in time. Also, after cleaning the bore of any of my rifles, I finish up with a Kroil saturated patch rather that leaving a dry uncoated bore.
In the applications that I have used it on, it doesn’t seem to build up or get gummy.
One problem though, you’ll probably love the smell of the stuff, but if you use it inside your house your wife will probably kick your butt or complain about the smell at the very least.

Like EMC2 I live on Lomg Island about 50 feet from the water. I've had a gun safe for over 25 years (American Security) I keep one "900 Gram size: 6" (15.2cm) x 3" (7.6cm) x 8-1/4" (21cm) corrugated carton. Protects 66 cu. ft." on the top shelf and one on the bottom. I've never had to recharge them. Never a problem in the safe, ever.

The very best solution I have found is with the goldenrod type fixtures.

They keep the humidity out. I would use the goldenrod with a dessicant - just be aware - dessicants attrack moisture. They suck it in from anywhere. The goldenros (or whatever you buy) pushes it out.

My experience only.
