I've always been a bit paranoid about storing my guns, in fact I use two safes one of them with windows as I like to look at my pistols, that are stored with a lot of small bags of
silica-gel. I get the guns out regularly just for some light lubing and I wipe them with some silicon cloth.
I keep the few holster that I still have in a locker, and from time to time I just wipe them with a clean cloth and some Ballistol, I bet everybody now is smiling knowing that in the last 30 years or so I've been a faithful user of Ballistol... almost like Hickok45...
