Opened up my 2 gun safes the other day and 75% of my guns looked like a big chunk of molded cheese.. the stocks were molded, the slings on my deers rifles were molded.. I grabbed the little hot sticks I keep plugged up in the safes and both were warm and working.. It has been a hot dry summer here, The safes are in my basement same place they have been for years.. I cant imagine what happend all of a sudden to cause this.. Is there anything I can wipe on the stocks and leather to keep this from happening? thanks!
