Moisture gun cabinet

I have a similar problem with guns going mouldy when left in the cabinet.

I have tried desiccants but they have not worked. I think I am going to go down the route of installing a heating element (aquarium mat or lockdown bar) and using a differential thermostat to keep the cabinet temperature above the air temperature outside so water cant condense on the guns.

I also thought about using a dehumidifier on a timer plug next to the cabinet but I recon that would be quite costly to run.
 
Snake reptile mat/cable will work at keeping cabinet above air temp, but you would need to run on a Pulse Proportional Thermostat so temp constant, not expensive to run (just the initial outlay),
if you have 2/3 cabinets side by side,cheapest option would be to use reptile heat cable (come in varying lengths), use sticky back cable holders & ties to fix to inside of cabinet, & one stat will control
length of cable (without any cold spots) if connected up properly - so can heat multiple cabinets from 1 cable & 1 stat.










I also use one of these in each of my cabinets, not once had an issue with rust in any cabinet.

 
It depends to a certain extent upon the location of where you store your guns / cabinet. For one clients build I was consulting on, I remember we introduced a simple passive air vent which allowed simple air change and therefore common temperature change in the gun room. The room was in a basement and was more damp than cold, but this did the trick - much in the same way as you have an extractor fan in the bathroom to exchange the moist air for dry air.
Temperature differential and associated moisture/condensation is our enemy in the battle against corrosion. Several friends have much older houses with solid (and often damp) external walls, where they had their cabinets bolted to. Bolting directly was introducing a cold bridge, where the temp/humidity outside was being transferred to the cabinet and contents inside. Couple this with the fact that older houses like these tend to be run hotter in the colder months and cooler in the warmer months, it was causing problems all year round. In the case where one of my friends had no practical option to move his cabinet, I suggested that he bought a 10mm thick piece of thermal break plastic (it has little or no thermal conductivity). We cut it to the size of the cabinet, templates the fixing holes and installed it (sandwiched between the cabinet and wall) - no further moisture/corrosion issues.
In my case, where I don’t have the above issues, I use a Napier sachet (which lasts for a few years, I believe) and also browning gun socks on all my shotguns and rifles (these help to prevent annoying cabinet scratches too). Occasionally when I buy boots or shoes I chuck the silica packets in too - with the above I haven’t had any issues for years.

I hope some of the above helps :thumb:
 
Thanks for your reply’s I don’t actually have a moisture problem at the moment but I like the idea of these small packs just to put in to the cabinet to be sure when putting guns back in after they have been out in the rain all day. Even though I clean and oil I think it would be impossible to get rid of all the moisture without a total strip down. Thanks
 
Putting guns away even slightly wet can be a disaster. Especially if there's a long time before you next get them out. After a wet day shooting, I'd do as anyone would and clean/dry them. But after that, I'd leave them out for any residual moisture to disperse. There's no problem sitting in the lounge watching telly/having tea or whatever for an hour or two, with it alongside you on the couch so long as the gun/rifle is under your control. It's a legitimate reason (cleaning) to have it out of the cabinet. Just lock the doors and all is good. Although I appreciate, depending on home circumstances, that might not be possible.

I would also be a bit wary of having a heated cabinet. You might find yourself with the opposite problem, especially if there's any wood, of drying things out too much over time.
