As the title states, I have a safe in the garage and recently put a hygrometer in there because I was concerned about humidity.

With the Texas heat, it's running 90+ degrees in there and showing 58% humidity.

This is with a goldenrod.

TBH I'm not the best with keeping everything oiled so would like to know whether I should be more proactive on the humidity, or if that is considered safe.

58% humidity isn’t bad. I’d want to know the tenp and humidity relative to ambient conditions outside the safe. As long as the inside temp is 2 degrees or higher than ambient temp and humidity is the same or lower than ambient, it’s fine.

To be safe, I’d add some VCI capsules. Hose down steel parts with Hornaday One Shot.

I store a lot of expensive CNC tools at 90F / 45-60% RH.  My experience has been that rust does not occur at these conditions.  When RH gets to 70% I get worried.

The humidity increases as the temperature goes down.  Wide temperature and humidity swings are bad.


Keep your powder dry, and watch your back trail.

I have a similar situation, 81 with 45-50% humidity in my garage. I have VCI tabs in my safe and all ammo cans that contain mags, parts, etc. You can get them from Uline.
Political correctness is a doctrine, fostered by a delusional, illogical minority, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

FWIW: the NRA museum keeps their firearms display cases at around 45%. Dry...but not so dry that wood stocks start cracking.
