Rust is the enemy of all metals, your guns included. Excess moisture in the air or high humidity will eventually cause metal finishes and surfaces to corrode which can play havoc with the sort of mechanisms present in all firearms.
To protect your guns, ammunition and shooting accessories, we recommend installing a dehumidifier within your gun safe. It will keep humidity levels low and prevent rust and corrosion from forming on anything stored inside.
We've tested several gun safe dehumidifiers and reviewed the best ones in this guide. We've now found the best gun safe dehumidifier so keep reading for our recommendation.
