Went on vacation and came home to find the sump pump had lost the fight. I had a humidity reading in my safe room of 80%. Most all the guns (overflow from gun safe) were okay but several in hard cases did not fare so well. I'm looking for some advice on how to get rid of the surface rust. The humidity is under control but the damage has been done. Most of the rust is on barrels, hardly any on receivers. Any experience in getting this under control?
