Storing in a safe

Affirmative on the vapor barrier down there. I poked around the other day when I was down there, but not to any great extent. Nothing looked amiss. I can put that on tomorrow's list. It may keep me off the computer for awhile and having no more Ka-boom's like at the range today (but that's in another area of the forum). [BooHoo] Thanks.

Air circulation.

My gun room is in my finished basement. My house is about 12 years old. Twice I brought guns home and had them rust within a week. Keeping them oiled helps alot. I bought a humidity guage and the humidity seem to vary from 40% - 65%.

I'd agree with the circulation suggestion. I also think wide temperature changes can cause condensation then rust.

I solved the problem by buying a water resistant safe and putting in four of those little plug in boxes. They last about 2 weeks before they turn pink. I have had 0 problems with rust in the last year.
