Where I live we have humidity up to 100% from time to time. We have to keep after our guns (and everything else) to avoid rust.
Going thru them once a month is what it takes.
It really takes a toll on your carry guns in hot weather. I've actually had perspiration kill the ammo I was carrying in summertime.
If I let my carry gun go as long as a month, it's rusted.
I live south of Houston, right on the Gulf of Mexico, and have never had a gun rust. At most, some these guns get cleaned once per year. Often times its 18-24 months before they get a quick wipe down if they haven't been used. I have quite a collection of guns, the thought of pulling them all out and cleaning them is a bit overwhelming.
Now, I can understand looking for any excuse to pull them out and tinker with them!
My area isn't very rust-active, especially if the guns get a silicone-cloth rub-down before storage. During the winter (non-shooting) months I like to take about a third of them out of the cabinet every few weeks for "re-familiarization". Meaning I fondle, cycle actions, and otherwise play with them while checking the bores and applying that silicone cloth. One of the few pleasures left from my childhood.
My guns dont get the traffic that a wood floor gets,
Therefore they don't get the amount of wax needed for that kind of protection.
Heck I only wax my furniture once every 2 years , just for moisture repellant.
So I haven't had a problem with buildup.
If its built up from 2-3 waxings , I cant tell it.
All I know is , it protects the metal from moisture/rust.
I have had guns sit in my safe for more than 3 yrs (unhandled ,waxed 1 time) and not show any sign of rust...
Buildup , I'm not worried about.
btw, if I want to remove it from the metal... a little wd40.
