Brass cleaning advice plz (barrel int.)

[Chemical-x.....ahain]

I've got an older KP with what I suspect is oil base paint in the breach area. I can see a buildup however i can't really reach it to attempt a clean. Im thinking some sort of chemical agent is my friend along with perhaps some nylon rope oversized to act like a boresnake.

what should I be using and doing?

[markdem]

Wd40 and some very fine wire wool on a stick

Before I attempt I'm curious if you've given this a good before

[markdem]

Chemical-x.....ahain yeah ive done it on brass and aluminum barrels.

If steel wool is too aggressive for you, you can use a cloth, it'll just take some more elbow grease

Pretty sure AnarchicArctic used some Ketchup and an old barrel swab. 😉

There may have been a power drill involved. 😋

[AnarchicArctic]

Yes! The acid in the ketchup does wonders. Swab it in there, let it sit for an hour or so, then rinse with hot water

why not fully disassemble,and soak the body in hot soapy water?t then just pull a piece of tee shirt through it.

Brasso on an old squeegee.

If it is oil base, it'll be difficult to get that solution to work. But if it's not I should be in luck.

I always used a cloth 12 gauge shotgun cleaner smothered in Flitz and attracted to a drill.

Isopropyl alcohol is what I use. Works great

I used a 3/8 wood dowel, cut a slit down center about 2'', slide through a piece of "0000" steel wool, and power drill cleaned mine, then after a good vacuum and wash out to get all steel wool fragments out, i put a piece of microfibre on same rod and power polished with polishing compound. worked like a charm for me

In order of preference all three will work on oil based paint and will not hurt the brass.

1. Aircraft Stripper (I usually have this on the shelf made for removing paint)
2. Acetone (Always have on the shelf)
3. Alcohol (usually have on the shelf but run out so often because I use it so much)

Now once the paint is gone polish up with Brasso on a barrel swab (or I prefer a 16 gage cotton barrel swab) chucked up into a drill motor.

You really do not need anything particularly strong to remove any paint from brass. Brass is super had to get paint product to stick to it to begin with.

I picked up brasso and some ultra fine steel wool, However in re reading the comments I took better note and I really want to try the ketchup trick first.

something about not having a way to scrape the barrel was bothering me, I decided to model something up. barrel scraper (paintball) by bluyben - MakerWorld worked well.
