Newbie to the forums here, haven't posted much, just been absorbing the wealth of knowledge and humor found on these boards.

I have an old Mossberg 500 ATP that was my dads, it has sat somewhat dirty for many years and I am working on bringing it back to life. This will be my first project, and one I really don't want to screw it up.

I have disassembled and cleaned it a couple times and brought it by the gun shop to see if they thought it was safe to fire. They gave me the go ahead so I put a box through it.

There was some light rust on the inside and outside of the barrel, I cleaned most of it out of the inside prior to shooting and the birdshot cleaned it up even better. Only a small amount remains at the muzzle end.

My questions are:

-Any suggestions on rust removal from the outside of the barrel without damaging the remaining blue? I have tried Hoppes 9 with a brass brush and this seems to work alright. I have also tried 0000 steel wool with some gun oil, I seem to have better results with the brass and hoppes. Should I try 000 steel wool or does anybody have some better suggestions. Im not overly concerned about the blue but would like to leave as much as possible until I get around to refinishing.

-Anyone have suggestions on cleaning the trigger group without disassembling? Boil it? Soak in iso alcohol? I have done everything I can with brushes and q tips.

-Is it ok to boil the bolt and bolt slide to try to remove some of the tough grime (very little amount) that just isnt coming off? Or should I try the 0000 steel wool on that?

Any help here is much appreciated!

:cheers:
 
Use the steel wool dry, lube will stop the removed particles from clearing away, creating a grinding paste. It just takes a little time with gentle pressure to remove it. I find birchwood casey gun scrubber followed by compressed air is good for trigger groups, followed by aerosol gun oil to lube. For tough grime, steel wool should work good, and if you get to a point that it just isnt coming off, adding a bit of solvent and letting it soak for a while will help. Just keep picking away at it and you'll get it clean. You'll have a hard time wrecking something with steel wool. Theyre tough and can take a ton of abuse so dont worry about screwing up.
