Safe question

I’m not a rocket surgeon but I know it depends on the temperature. Higher temps hold more moisture so 40% at 70 degrees is not the same as 40% at 90 degrees.

The problem is that 40% is not going to be consistent. Every time you open and close your garage door those numbers are gonna change. Your garage is not climate controlled in any way, shape or form. You could install a window AC unit and that would help a LOT, way more than desiccants, dry rods and anything else along those lines. But you are still going to have a dramatic humidity change every time you leave or come home.

Negative. An AC unit is the worst thing if the garage is not properly insulated. If you get an insulated garage door and insulate the ceiling then ok, otherwise you are drawing moisture in with an AC.

The dehumidifier in my garage is the first barrier. I’m making a better environment for the safe to be in, then I’m treating the safe as well of course.

And I probably am going to get new doors, insulate it, and put in a split unit but not the point of this post. I can get the humidity in the safe lower. I’m controlling it easily. My question was if 45% in my safe is adequate or if it should be lower.

You are correct. Didn't realize your garage was not finished.

Honestly I wouldn't get too comfortable with any humidity percentage. If you are going to store them in a safe in a garage, maintenance is going to be your number one defense. I'd do a wet patch and wipe on everything every few months and store them almost wet.

Southern states are a PITA for this stuff. I lived in South Florida for 30 years and I've seen a lot of gun nightmares. Worst of course are those who were dumb enough to "store" them in their roof attic. This includes one guy who put his fathers "theater capture / papered vet bringback" WWII P-38 and all his fathers medals in a box that he put in the attic "oh about 10 years ago."

It was in really sad shape but I didn't want to rub it in. Non gun people shouldn't be allowed to inherit guns.
