MPro-7 for carbon removal

[45-70 Ranger]

Something on cleaning that I found to be helpful in cutting the carbon around the nipples on the cylinder.


I bought some MPro-7 cleaner to try on a .22 revolver that has has a alloy frame with a baked on finish. I wanted to clean it well, but not remove the finish with Hoppe's #9. (The mfg. of the weapon strongly advised against this practice as it would harm the finish) So I tried the MPro-7 and had great results with no damage. Troops use this cleaner to get the carbon buildup off their autos and it is very effective for them. And we all know that were in the service or own an AR, that they will get nasty with carbon.

Now to our beloved BP wheelguns! Like nearly all of us, I clean with hot soapy water, or at least water, to get the fouling out and off my weapons. The deposit of carbon at and near the nipples is always a bear to get to and clean with total removal. The MPro-7 was sprayed on the nipples and rear of the cylinder and allowed to soak for about 5 min. Then sprayed again and the carbon came off fast and clean with a toothbrush. It got all the carbon off and left it void of crud, carbon, and oil. I then simply coated the area with my usual oil and shaving brush system I've used for decades and the weapon was good to go.

MPro-7 claims this cleaner will kill corrosive material (BP included) on contact. Haven't tried that as I clean my weapon after shooting and with water, so I can't say for sure there...But it does get the built up carbon and will pull fouling from the bore after cleaning well with soap and water. Pretty impressive, and I'm not easy to impressed either

Have fun and be safe,

IF it gets cap residue and carbon/BP fouling off easily, I'm impressed, too.

Yup! It took out the cap residue and all the gunk that gets in the nipple area like nothing I've ever seen. Best part is that this stuff is non-flamable, bio-degradable (hope I spelled that right), and even gets to the lead and such by lifting the carbon under the lead and making it kinda rise to the surface, so to speak. Not water based either, and didn't take any of the finish on the .22, and got a little on the grips, but it didn't leave any residue or hurt the wood finish. Pretty neat stuff. But it is costly, about 7 bucks for a 4 oz. spray bottle. But a little goes a long way. I just use it for hard to clean stuff, like the nipple area and around the frame and hammer. Cut my cleaning time by half. But like I said, I'm not that easy to impress with new-fangled things, but this does what it said it would do. That's good enough for me... and it has no smell either, so mamma won't hollar bout the solvent stink we all love so well!

I clean my BPCRs on the range with the Venturino standard of diluted Windex + Vinegar but I reclean at home with M-Pro 7. It does as good a job on black as smokeless.

I've heard that MPro-7 is the same stuff as Hoppes Elite GunCleaner. If so, I'm a fan of MPro-7 too. I've been very impressed with how well the Hoppes Elite removes carbon fouling from smokeless powder--even in difficult spots like the front of a revolver cylinder or around the forcing cone. Most of it wipes off with a paper towel. I imagine it would work very well for BlackPowder too.

Thanks for posting this thread. I picked up a bottle of M-Pro7 last week and gave it a try this weekend on my Rogers & Spencer, and an M-1944 Mosin-Nagant after shooting corrosive ammo.

I put 40 shots through the R&S, load was 30 grains of Swiss 3Fg. I put 50 rounds of early 1960s Soviet light ball through the Mosin, plus another 5 rounds of Hungarian light ball. The Soviet ammo is some of the dirtiest "smokeless" ammo I've ever shot.

The M-Pro 7 worked better than pretty much anything else I've tried at getting out the carbon fouling from both guns. Bore patches were coming out clean after about 6 passes through the bore.

I followed up with Ballistol in case the M-Pro 7 was leaving stuff behind, but these patches came out clean as well.

I inspected both guns 4 days afterwards and neither had any corrosion on them.

It is amazing that something which is not noxious can be so effective. I'm sold on the stuff.

Yeah Dave, it is some kinda neat that it does't stink. They make a cleaner/Lub called, if I remember right, LPX, and it is IMO, even better than Breakfree CLP in it's use. But the M-Pro stuff is pricy! Good thing is that a little goes a long way.

I did a little test with the cleaner on m old Dragoon I've had since '69. That baby's had a bunch of rounds put through it. The weapon was clean as I knew it to be. Hot soapy water followed by the usual cleaning style we all use. Then it was cleaned again a week later with CLP to make sure all the fouling was gone and it was well oiled to prevent rust.

I cleaned the weapon again without firing it, with the M-Pro 7 cleaner and I was dumbfounded. There was black fouling comming out of the barrel that the two prior cleanings missed. Followed with the LPX after getting clean patches for final coat of the weapon. Yup, GOOD STUFF...I just have to keep an eye out for when it goes on sale

if it can remove Remington percussion cap residue i am sold. can i use it to clean the inner workings of my NAA mini revolver? i had to replace the hand spring on it not too long ago and once i did that i realized how much gunk gets in there, and i don't think Windex would work for getting rid of that. could i possibly remove the grips and soak it in that MPro 7 stuff to get the junk out of my revolver?

 

[45-70 Ranger]

It does that too.

Busy,

The solution has been used in diptanks for quite some time. The mfg even stated that one can remove the stock (grips) of a weapon and simply soak the entire weapon if one needed. Be advised that the cleaner WILL remove all traces of oil present. So after cleaning, one must oil to perserve and lube to keep things running.

As far as the crud on a Remington, I can assume so as even my tiny Wells Fargo mod with that little area on the rear of the cylinder gets squeaky clean in a 3 to 4 min. soak after the initial spray. Then one additional spritz and I hit it with a toothbrush and Q-tips to soak up the stuff brushed off.

It is some amazing stuff, but as I stated earlier, it is not cheap. I think a 4 oz. spraybottle was about 7 bucks...I don't use it each and every cleaning, but when I see that crud is building up and I cn't get it with standard stuff, then I get the M-Por 7 after it...That way I won't go broke using it all the time....(Hey, I'm on old man on a budget )

I know it sounds like a salesman or something, but I am not easily impressed with new stuff. I've seen things come and go in the last several decades. Thus when something does something amazing I take notice. Then IF it proves to me, the old skeptic, that it works, then I feel I should advise those that are as involved in the sport as we are of what I have found and personally know about it.

Hope that helps a might.

i will be sure to try that stuff! i did just clean my Remington Rider Pistol, i used some Windex mixed with vinegar and just a touch of alcohol. I put some on a Q-tip, rubbed it on the breech and it got blackened with residue really quick. i cleaned the bolt, the barrel, took it apart and cleaned out the innards, and then oiled it and put it back together! it seems to be a good cleaning solution for someone who doesn't buy to many accessories. however i do want to give the new cleaning stuff a try. that would be great!
