Whats everybody using for cleaning and for rust prevention while in the safe? I watched a video earlier of 6 or 7 different gun specific anti rust treatments along with plain old WD-40 and the WD performed as good or better then the best firearm specific product for rust prevention. I'm just looking for something to use while the guns are stored in the safe and not something long term like Cosmoline. In other words something that I dont have to remove before I want to go shooting. What say you?
