I would like to point out that the ultrasonic cleaner I picked up this week from Harbor Freight - the $70 model - is great for cleaning brass.
It is also great for cleaning steel, like the steel in a bolt carrier/bolt. By "cleaning steel", I mean "removing all the finish from". I now have a bolt & bolt carrier in raw steel! Great.

I ain't got a clue to what a ultrasonic cleaner dohicky is... I normally just use a toothbrush and some Hoppes #9 and let sit for a few minuets. And also a Q tip . Im sorry to hear of your mishap... WarDawg

What solution did you clean it with in your ultrasonic cleaner? Did it remove the parkerizing?

I’m also interested in knowing what type of solution you used. The ultrasonic waves alone can not remove parkerizing. I’ve used ultrasonic cleaners in aviation, on parts a lot more delicate than a AR bolt!

+1 for aviation uses. Been there, done that. I'm wonder if maybe this guy had a chromed bolt to begin with and had just never seen it clean before...

sorry guys, life has been busy. I used 50% white vinegar, 50% distilled water, and a few drops of dish soap. I'll get some pictures tonight.

That's a great cartridge case cleaning formula, but not so sure about cleaning bolts/carriers/barrels. I've never heard of a home brew that used vinegar as a basis for a cleaner, except as a lead remover when mixed 50/50 w/hydrogen peroxide.
I've always wondered if you used a dedicated cleaner, like SLIP 2000 Carbon Cutter or Milcom's cleaner/degreaser product in a sonic cleaner, if that wouldn't be a simple and effective method. I could see just plunking the bolt and carrier in a glass beaker, filling it up with product, and tossing it in the tank for a couple of minutes while you take care of the barrel. By the time you're done, wipe cleaned parts down, put some CLP on them and slap back together. Voila! |

I was thinking of picking up some Kroil or possibly transmission fluid. One problem is filtering the stuff for re-use. |

Ancient Roman Prostitutes used the very same formula as a douche.  Sorry about the hijack - but I couldn't help it.

Here you go. The grey area in the middle is very rough - the other areas and smooth as normal.

Could the Vinger etched the steel?
Why would you use vinger and acid to clean your rifle??? Brass becomes nice and shinny for the acid eats away some of the surface material. One of the reason you do not want to use acid to clean brass. Vinger is for salad dressing. Whats next olive oil and vinger as the new CLP? Spray the whole BC with brake cleaner then take a pic. It def not as bad as you were pointing out. |

That gray area looks just like my carrier after using SLIP Carbon Cutter. Just lube it up.

+1 Not sure how much additional cleaning (using more conventional means) that you have tried after this, but try giving it a good scrubbing with brake cleaner to take off any residue (and any stripped finish) then give it a good soak in CLP. It should bring it back. As it looks right now, even if the finish is stripped it shouldnt affect performance, you will just have to be more religious about cleaning to prevent any kind of corrosion on unprotected surfaces. |
