Ok, I am new to firearms ownership and I need to check on a few things.

1.  Is it really ok to use break cleaner on your firearms to help clean it up (instead of more expensive things like Breakfree Powder Blaster)?

2.  Is it better to use the non-clorinated or clorinated break cleaner?

Sorry, for asking this as I am sure it has been addressed before.  But since the search function is not working yet, I thought I better ask before I start spraying.

I use it on some of my guns when I am really wanting to get all the carbon out in a hurry, but dont let it get on plastic or wood, and remember: brake cleaner strips all lube away, so give everything a nice coat of oil afterward.

On metal, it's fine...on wood, it'll remove the finish. On plastic, it may melt/deform the plastic, depending on what type of plastic it is (I damn near ruined a pair of AR handguards...)

On metal, also, you sorta need to treat it like you just dunked it in water because it strips it totally down; lube/oil will be the order of the day after you've cleaned it.

Carbureator cleaner is designed to dissolve carbon deposits.

Brake cleaner is a de-greaser.

They are usually much cheaper than the very similar products labeled "Gun" this and "Gun" that.

As noted above, be careful about what it contacts, and mind the fumes.

Use it liberally. My AR stocks are fine, despite having had lots of brake cleaner on them. However, cherish your rifle as you cherish your ass - WIPE! Also the guys are 100% right when they warn that it dissolves all the lube. Be sure you put oil back where it belongs when you're done.

I use B12 ChemTool all the time to clean the bolt carriers on my ARs.
Stuff works GREAT, but as mentioned, it removes ALL lubrication. Make certain you have a good lubricant handy and have at it.

You can use brake cleaner. For a new gun, I would test the solvent on a hidden spot especially on plastic parts. I now have a slight finger print on my CZ75's plastic grip panels. Hoppes #7 will soften that plastic.

Thanks one and all.

It sounds like I should use carburetor cleaner to get those stainless guns clean quickly and not break cleaner.  

Proper lubrication afterwards, that makes sense.

Thanks

Also, if you are with a girl whose mouth says "No, no, no," but whose eyes say "Yes," you can spray some brake cleaner in her eyes, smear some Hoppe's #9 on her lips [No Kissing!], and go to town!

CAUTION Do not cross state lines to do this.

Break Free Powder Blast will discolor the finish.  I advise against it.  I used it on an AR15 extractor to test it for discoloring and it turned the extractor a rust red color.  A LOT of rubbing with Remoil and it finally went back to its original color.  The only finish I use it on now is stainless steel.

You are referring to BRAKE cleaner right?  not Breakfree or break like break a bone?

If it is indeed brake cleaner, I know alot of tact driver long range shooters that use it to break in barrels simply due to the volume needed to break in the barrel.

Brake cleaner will NOT harm plastic or rubber. Carb cleaner will eat the shit out of most things non-metal. I don't know why you guys say brake cleaner ate your handguards or whatever, that's bullshit.

I heard it eats some types of night sights

Okay, so Brake cleaner is OKAY for cleaning most parts...
What about alternative lube?
I know I can use old tractor oil in the AK, but that'll run with anything or nothing.

Anyone ever use bearing grease? I find things to feel much smoother with that than your basic gun-oils. How well does it attract carbon?

There is more than one formula for "brake cleaner".  The slow evaporating versions, like CRC are less active in attacking plastics and wood finishes.  The faster ones that contain Toluene WILL attack many things.

I use both, each for its purpose.

I guess that's a matter of alcohol content

I have used (IIRC) Valvoline Durablend bearing grease certified for CV joint use.  Excellent stuff, with a very wide temp range.  A $6 tub will last a looooong time.

I never knew you had to clean while taking a break, I'll have to look into that!

I used a couple cans of it to clean my new SKS, it ate the cosmoline right off ot it, did a great job.  The wood didn't have any kind of finish on it in the first place, so I wasn't worried about that.

Carb cleaner / gum cutter will attack plastic much faster than brake kleen will...

As no one else has cautioned--when you spray stuff with it, be VERY careful not to let it splash back in your eyes.  I wear contact lenses and it's very exciting every time I let it happen (slow learner).

Yeah, that does break up the monotony of gun cleaning. I have found that it expands my vocabulary, as well.

Wally worlds sole purpose on this planet (to me) is to sell cheap ass brake cleaner!

Speeds the cleaning process way up.

Andreuha: I use bearing grease to take away the "AR music" in my Colt HBAR. Works pretty well, only took a handful.

The noise isn't so bad on my Panther shorty so I haven't done it with that one.

As far as the rest of the lubrication on an AR, I use Rusty Duck on the extractor and TW25B everywhere else. Period.

It seems to me that you could use just about any other lubricant on an AR as long as it's not too thick. I think someone here on this board even uses Castrol motor oil on theirs. Pick and choose, experiment if you like. But I've done a little experimenting and have settled on TW25B for ALL my firearms.

Good news
I already use Castol Bearing Grease on an AK, but haven't tried it on anything else...
