For us non techie types, what % of humidity would have to be constant to start rust. We are in PA and yes it is humid. I run the a/c when it is hot do not like a/c rather have the breeze but this summer has been hot so the a/c is on.
I have a dehumidfier in the same room as the safe and my electronic meter reads 45-50% most of the time in the room.
The safe is not opened much and so far I do not see any rust.
Just curious how high is too high
