Picked this up the other night

I have used steel wool numerous times, but always be careful. You can use balistol (SP) or other oils to help loosen up the rust. Even better than steel is bronze wool, its softer - but never use steel wool less than 0000 go easy and use oil.

If you feel that you are in over your head, then re-think about doing anything. You can go see your local gunsmith but be very specific what you want cleaned and how much.
