My stainless Remington barrel on my 700 and my 10/22 barrel (also stainless) are both rusting. They're in a safe with my blued guns, which oddly enough, don't show any rust spots (i'll check again tomorrow when i can see better, though). A break-action airgun though stored in the corner of the room is peppered in rust spots. Like if you move your finger along, it feels bumpy with rust. I don't know if it has a finish, it just says "Made in USSR" lol. What's the best way to fix this? I don't want to tarnish these guns, of course. Thank you for your replies!
