What's the best way to get rid of rust in a hurry? I went on a camp/hunt trip this weekend, and had my rifle in a hard case. Apparently a severe weather change has adverse effects on polyfoam liners of hard cases and the blued steel of a rifle. I went hunting Friday, came back to camp that evening, put my gun in the case, and went to bed. (temps around 50F) Woke up to rain and shit Saturday, with temps in the 30's. Rain didn't stop all day, came home. Today, get my rifle out to discover the trigger guard, bolt handle, mag well/mag and barrel are RUSTY! I have usually used a rag with gun oil to remove the rust on my other rifles, however, some spots seem deeper than others. Oil and rag, or should I try something different? Any help?
