Is there an easy way to clean the trigger group of an AR15? I don't like to douse it in cleaner/slovent because there is grease I put in the pin and inside the trigger and hammer axis. This would require a full disassembly too apply correctly again. Do you just wipe it clean from the outside?

I don’t shoot suppressed because my state sucks. But I usually just squirt a bunch of CLP in clean up with Q-Tips and let it leach out onto a rag. If I do a deep cleaning on anything I take it apart completely.

Wipe down the interior of the trigger well as best you can and lube as necessary.

Air for sure. Non chlorinated brake cleaner is good but definitely strips out the lube. One thing that works in the interim is a shot of windex or other light household spray cleaner and a small artist's paint brush. Give it a squirt, use the brush to loosen up crud in the corners, another quick squirt with clean water,  blow it out with compressed air.

The Q-Tips with a long wooden handle from Brownell's work pretty well to wipe down the hard to get to places.

My 300 gets caked with carbon in the lower shooting suppressed and I've found that my air compressor does a good job blowing that crud out. Then long wooden cleaning q tips for any hard to get spots. Usually don't need to do that though.

I’m a long wooden q-tip fiend. I buy them by the thousands and will use about 50 each time I clean. I also started buying the swab-it foam Amazon knock offs. They are super cheap compared to the real (overpriced) Swab-It’s.

Contaminants will sit in the grease with or without cleaning. If they’re in your trigger pins you will have to remove the grease to remove the contaminants.  I wouldn’t do more than wipe down excessive contaminants and move on until you think the pins should be removed and cleaned.

Basically the same here

After blowing out the brake cleaner I spray it with a spray lubricant (I use Tri-Flow) then blow out the excess lube and wipe it down.

I mean, it takes <60 seconds to remove the grip and trigger pins…if it’s that bad just remove them and clean it. In between those times, a little CLP and some long wooden q tips work just fine.

Best degreaser.  Leaves a thin oil coat instead of bone dry.

For a finer point..............Floway is the best for this project.  It is twice as expensive as brake cleaner.  But because you use so little, and it is so much better, this is what I use on all my trigger groups.

Hose out with brake cleaner. Then spray with lube.
Wipe any lube that weeps/wicks to the outside.
Get the chlorinated brake cleaner, too.

Good way to do inside the upper, too.

And BCG.

I find claims of something being a great degreaser and then also being good at lubricating after the fact to be suspect.  

If it was such a good degreaser... how is it going to leave grease behind.

Never said it was for lubricating.  And KANO does not even mention this property in their description.

And I agree with your position.  Why CLP always seemed strange.

Floway gives you a just a little more time between degreasing and surface rust.  It cleans just as well.

That's what I use.  The non-chlorinated stuff is usually a mix of acetone and methanol which won't hurt anything (acetone doesn't disolve nylon).  I use Gunzilla on a brush where I can and then squirt liberally with brake cleaner and then a few drops of oil.

I brush off as much crud as I can with a solvent soaked brush.  Then I spay brake cleaner to to remove the solvent follies by compressed air blower.  Then apply lube.

If you don’t want to use solvent use a dry brush, no brake cleaner and compressed air.

I just fill up the sink with hot water, and put some simple green hd in it, and dip the lower in there and scrub it with a brush. Afterwards I run it through the clean water for a few seconds and then shake it and use a air cleaner and some q-tips to clean up. Afterwards just oil as desired.

It's really just metal that's no different from cleaning any other kind of metal. Do you use brake cleaners on your pots and pans after cooking with them? Do you oil your grill after you clean it and spray it with water? So why would a firearm be any different or react differently to the same procedures?

Try it one time. You'll be pleasantly surprised! Fill it up with hot water, some purple green hd or dawn dish soap, and scrub, wash with clean hot water, and then dry it out. It won't rust, and it'll be cleaner than it was before. Not a joke post btw.

The only sort of "famous" youtuber who is probably one of the better youtube gun channels even clean his rifles and pistols with water and soap:



I clean it very similarly but instead of a bar of soap or separate water tub, I just combine it to a water/soap solution. Shooting suppressed will make it even dirtier so scrubbing it inside the water is a better idea.

Couple points:

1. Do NOT use chlorinated brake parts cleaner on ANYTHING EVER. That shit will cause metal fatigue and tiny cracks over time. Look it up.

2. Just blowing into a dirty receiver with a high-pressure air nozzle, will also force some grit into small places as well as displace some. Air should only be used to dry it all out after hitting it with whatever cleaner.

3. "Oil if it turns, grease if it slides". Grease is not necessary in the pin holes of trigger parts, oil is fine, grease should used mainly on slidy parts. So it works just fine to use the cleaning method many have described in this thread, non-chlorinated brake cleaner, followed by air, followed by spraying lube using a tube to get right in there where pins go through and get some inside, drip/wipe excess oil, then grease sliding parts lightly.

ETA: Not sayin grease is wrong for pin holes, just saying if you don't want to break it all down during a clean, then oil is the way. When I first assemble a rilfe I usually grease the holes, and also if I do a deep clean where I take everything apart. But for in between, hosing it out and showering with oil is the way to go.

Works well.  Just have to ensure everything is DRY and then lube it.  Pretty common to clean out black powder firearm actions and lockwork by scrubbing submerged in soapy water.

Personally, I find Brake Cleaner to be way easier.  it evaporates in 87 seconds then spray some lube in there.

Chloride/Chlorine induced stress corrosion cracking is not an issue at all for cleaning an ar15.

a) Mostly only affects titanium alloys or high nickel content alloys (ie: austenitic stainless)... neither of which is a concern for cleaning an AR15.  The receivers are aluminum, the tough hard bits are going to be alloy steel, springs aren't stainless,  416R stainless barrels are martensitic (not austenitic), and 17-4PH stainless parts are duplex (not austenitic), and any screws you have that are "stainless" should be a high strength corrosion resistant alloy and not garbage soft 18-8/304/316.  The only thing I'd be concerned about is brake cleaner softening or melting polymer - and that's easy enough to check on a small obscure location before hosing it down.  

b) Even if you had susceptible stainless alloys on your AR15, which you shouldn't, it's simply not an issue at room temperatures.  Chlorine induced SCC in ferrous nickel alloys occurs almost exclusively in temperatures over 60C/150F.

Yeah, I've spent many an hour scrubbing BP guns out in soapy water, just never a lower receiver group.

Carb cleaner and compressed air followed by aerosol G96 is my preferred these days.

If you switched to oil for where you apply the grease, you probably wouldn't notice, and it'll give you more flexibility to clean the area.

Anything with a name starting with "chlor----" should be kept away from metal. Perhaps if you have nothing else and you must spray it then it is probably okay but definitely consistently using it will weaken the metal. Maybe not enough to really notice and most likely will take about as much time as simply shooting the barrel out but it's definitely weakening the metal.

So you didn't read what the supplier has to say? That's why I posted a link. I'll repeat myself. No company is going to expose itself to the liability of damaging automotive brake components. Some auto parts are rated as Safety items, including brake components.
