Hello all! I'm new here on the forums and just had a quick question. I own a Remington 870 express for home defense and hunting. problem is I've had to keep it in storage and locked up tight because I've been away on business a lot(no deer hunting for me this season! ). I took it out a couple of days ago just to make sure everything was still nice and clean and I found a tiny bit of surface rust just above the ejection port. I would like to know if there is any way to clean this up and how I should oil/grease my gun up better for storage, until i am home more often. Any help or advice would be greatly appreciated!
