    So upon further inspection of my muzzle break, I noticed a crap ton of residue left over from corrosive ammo I was shooting a while back. Any ideas on how to clean this easier? I've boiled water, let it sit, and scrubbed it to hell. I've let Ballistol and CLP sit on it for a while and tried scrubbing. In the pictures you can see spots of where it started to come out and there are spots left over that are tough to get out. It kind of looks like rust in the pictures but its not. I think it's cause I took the pictures with my phone's camera.

    Not sure what you have there- possibly metal fouling. When all else fails- KROIL. Let soak for 24 hours. If there is anything there that should not be, KROIL will get between the base metal and the fouling, and break it loose. Brush lightly, flossing not required.

    How is Kroil on finishes, and do I need to completely submerge it in the oil or just coat and soak for 24 hours? Thanks

    Kroil is a penetrating oil- never had any problems with bluing and Kroil. You can spray it or swab it on, let set.

    I don't recommend it on nice personal guns, but when I was in the service I would chip that kind of crap out with a pocket knife. The Marine Corps even gave me a scraper tool designed for it.

    I'll try Kroil out, thanks.

    Eh its a personal gun, but its the inside of the muzzle break so if thr Kroil doesn't work I'm using the pocket knife.

    Vinegar.(brown vinegar is the cheapest)(straight, do not mix)

    1 part Janitor's Ammonia, 2 parts water and a teaspoon of Dawn. Mix.

    Brush cleaner. (straight, do not mix)

    Apply with Q-tips, clean up excess, use

    one super-secret-patented-this -must-be-your-lucky-day

    formula at a time, allow time to work in, wipe off.

    Windex!!!!!!!!! Took all the residue off my ak quick... Let it sit for a while and rub off... Make sure u let CLP sit in it after to make sure the windex is all gone..

    Put a sign in your front yard that reads "Gun Free House" & see where the criminals go.

    Idk if I'm sold on the windex thing, so much back and forth debate. Ill stick to water.

    But this caked on **** is from over a month ago. It slowly came out in spots but I need to try some Kroil or some of those homemade recipes on it.

    I bought my ak from a friend who I witnessed shoot over 1500 rds of both steel and brass corrosive ammo over the course of 1.5 years... Never cleaned the gun once!!!! I got it and was in shock there was 3 mm of crud on the tip of the piston that even after soaking didn't come over very easily... All other parts were laid on the table and sprayed every 2 hrs with more windex and the next morning all that residue wiped right off!!! Personally I would never shoot corrosive ammo in my AR15.... Where did you even find some?

    Isn't it just the water thats dissolving the corrosive salts that build up? I don't think ammonia does anything to it, especially since its a small amount. It was bulk Russian surplus from aimsurplus. 5.45 1080 tin was cheap

    ;) I told my mom I wanted hoppe's air fresheners for my truck, she told me to just dump kerosene in the carpet. I say "Ma? I smoke. I don't think that's such a great idea."

    Quick google search shows that u r right but at least the windex will evaporate away from the spots you just can't get into wipe...

    I used it and it works for me... Use whatever u want.

    Windex is pretty much just water and ammonia.

    The janitor's ammonia is much stronger.(and a lot cheaper)
