#4807449 - 07/07/18 08:47 AM Brake fluid as a bore cleaner?

So I am watching YouTube and this guy is testing all sorts of gun oils. He would burn some gun powder, on a piece of steel and then test different gun lubes and cleaners to see which one removed the burnt powder residue. I was bored yesterday so I tried this myself and found some interesting results. I tested lots of different gun lubes, home brew concoctions and firearm solvents that I had on hand plus some other oils and cleaners I had on the shelf too. The results were pretty amazing (to me). So to cut to the chase, plain old Valucraft brake fluid was one of the best at removing the burnt powder residue. Is there any reason you can think of NOT to use brake fluid to clean a barrel bore or firearm internals exposed to burnt powder residue? Would it attack aluminum, SS, poly frames or others parts? I would also assume its not safe to use on wood stock finishes.

The big problem I see is that brake fluid is Hydroscopic, absorbs moisture. so if you use it, I would wash the bore well with hot water. Then follow with WD-40 to get out the water. Then oil.

This sounds like a lot more work than good ole bore solvent.

Thanks for your reply. I tested good ole' Hoppe's #9 solvent too and even though it gets great reviews it couldn't hold a candle to brake cleaner which I found interesting. I'm not proposing leaving brake cleaner in the bore or internals or using it as a lubricant but merely as a cleaner. I do see a red flag to it being hydroscopic and should be thoroughly flushed out though.

If I put my nose to it - OR if I see the wife, kids....etc... running outside the front door in a hurry, I do not buy it for cleaning / lubing / preserving my guns.

If you can afford the phone/desktop and internet fees, you can afford a gun cleaner that does not create eventual health problems. So many folks here spend money when they don't need to and don't spend money when they need to.
Worst scenario?...... spending money to use the product in the wrong manner.

Are there health risks using brake fluid?

My second reply should have read brake FLUID and not brake cleaner. I am unable to edit the thread for some reason?

I'm not sure about brake fluid as a bore cleaner. The old formula GM Top Engine Cleaner was great for cleaning up powder fouling. The bench rest shooters did it all the time. I tried it myself and it worked very well. It was best done outdoors though.

Interesting. Which DOT number is the brake fluid you tested?

It's not. And that alone would steer me far away from it for gun use. A lot of automotive brake fluids have warnings right on the bottle, to not allow it to come into contact with painted surfaces. So why risk using something on a gun that could damage some part of it? Back to the risk vs. reward factor. None to be had.

I would stick to solvents and cleaners that won't hurt any part of your weapon through accidental contact. The health risk to using any these products is way overblown. It's not as if the local cemetery has a section for people who have allowed themselves too much contact with brake fluid and gun cleaners.

I would use it taking care to stay away from areas not to be cleaned. Wear gloves and follow the cleaning with a light coat of a trusted gun product to protect those clean parts. Try it out on a lesser value weapon for a few months and see for yourself.

Are we discussing "brake fluid" or "brake cleaner"? Huge difference.

CLR really cleans out bores, but itíll take the bluing off, too. Donít ask me how I know. whistle
