What % should I set the dehumidifier at to keep guns from getting rusted?

60% average....You need some moisture, otherwise your wood dries out.

Thanks. You just saved the planet because I was setting it at 50%

When I say 60% average, it could be anywhere from 55 to 65. But if it's a good model and holds at about 60, you should be okay.

I keep mine at 60%

It is difficult to get to 50% in NJ in the summer. Big bucks in energy for little effort. 60% is a good number for the summer.

 

I have a problem with the 'stocks need some humidity' statement though - what do you do in the winter to keep the humidity above 40% in your storage cab - put a bucket of water in there?? :shock:

AAHHHH. Thats the kicker. What type of heating do you have? If you have base-board heat you'll have no problems with humidity. If you have forced air, you are out of luck.

You then need a Humidifier to even out the moisture in the air, or have one built into the system.

If you have base-board heat you'll have no problems with humidity.

 

:roll: 10% RH with an OA temp of 32 deg F means you have less than 10 grains of moisture per pound of dry air - baseboard or scorched air heating has little impact on how much humidity you have.

Okay.....What we're talking about are two different things. Bench lab project, versus the real world. The humidity in anyones house is controlled by a lot of factors. Simple things like a

cooking stove with pots of boiling water, a nice hot shower. All these things put a lot of moisture in the air. Depending on how well your insulation is, that moisture is trapped in your house. Base-board heat only heats the air that's in your house. Forced air heats and dries at the same time. Get the picture... Everyones house is unique. My suggestion is to get a

hygrometer and measure the relative humidity in you own house, get an average, then decide your best possible solution. Ever notice the sweaty windows in the wintertime?
