Why you need a humidity trap/dehumidifier in your safe...

Where is everyone? It would be interesting to see what local climates do. I only have 50% humidity at the moment which is pretty standard for year round. Temperature outside fluctuates greatly (snowing at the moment ) but inside is with 4 degrees year round where my guns are stored.

Aha the joys of living well inland down south (3h from the nearest ocean) no salt in the air and very rarely excessively humid having said that I did have an issue with rust on firearms when they were stored in a tin partially open shed. Which is why I moved my safe into a brick enclosed building and put 1kg of those silica crystals in the safe.

Interesting
You'd be similar to me then,guessing i have altitude on my side. The crystals are my choice.
My walls are a Styrofoam box.
