Marvil mystery oil

[1johnlb]

I have a Enfield that has a mint bore. When I got it, I could still see the blueing in the bore but over time shooting cast it turn silvery in color. I thought the blueing had just worn off. I had a bottle of MMO sitting on the shelf, and still not sure why I even thought to try it as a bore cleaner, hopps#9 my normal cleaner sitting beside it. Well decided to use it with the bore hot because that's were MMO works with engines. Now after about 3 sessions with it I'm seeing the original blueing in the bore again. Is anyone else using MMO?

no, but i do use butchs bore shine with about 20% of kroil mixed in. imo hoppes is a pretty ineffective bore cleaner.

Hi,
Go one better and mix up some "Ed's Red" I use the MMO in place of the Dexron Tranny oil and works great. One gallon last a LONG time and is the best I've ever used for shotgun bore cleaning!!!

+1 on the Ed's Red. I have not found anything better in the years I have been using it. Also the Ed's oil version which is just the kerosene and dextronIII mixed is the best machine oil I have used. I will try some with the MMO.

the stuff sure smells great!

+1 on the Ed's Red.... the price is right too!

Only half joking with the successes I've had over the years with MMO for various uses I'm beginning to wonder if I should add some to my regular diet. It sure seems like some pretty handy stuff.

might help if your plugged up !! LOL

Nevered tried MMO as a bore cleaner before. I have a Mosin with a dark-ish bore. I'll see if that brightens it up at all.

You might be better served with a little lead in the bore, it sure does shine up a bore pretty good. I have a 8mm mauser that had a dark bore and after shooting a couple hundred rounds of lead boolits it's as shinny as a new one. Really can't say that it shoots better but it does look better. MMO so far looks like its stripping that fine layer of lead off everything I have used it in. I'm using it at full strenght on a hot bore and the lead comes out on the cotton patch.

Still working on a cast load for this, but will give it a try as well. Thanks

I use the Marvel Myestry Oil to lube my rifle cases with for resizing,have never stuck a case yet.I just barley wet the tips of my fore finger and thumb and smear it over the cse to be resized.Good stuff.

I have read somewhere, can't remember where I read it though about using Marvel Mystery Oil as both a bore cleaner and for lubing cases and the writer noted in the article that his case life had decreased after starting to use the MMO. I think I will stick with Imperial case lube. I use Ed's Red and love it as well as a bore cleaner.

Hi,
+1 on Imperial Case Lube! None better!

Out of curiosity I did a bit of searching and found this on bobistheoilguy.com -

70% Light Aromatic Oil (Pale Oil)
- It is a Naphthenic Oil, so while it oxidizes faster than a Paraffinic oil, it does clean and dissolve sludge and carbon well and cleans up after itself from any oxidation. serves as base oil as well. [Naphthenic oils have more solvency and are more polar (they are attracted to metal more), but oxidize faster.

29% Mineral Spirits
- Cleans Varnish very well. General cleaner. Also acts as an antioxidant.

38 parts per million (ppm) Boron
- AW/EP agent, friction reducer, antioxidant

900 ppm Phosporous
- AW/EP agent

1/2% 1, 2 ortho-Dichlorobenzene
- EP agent as it interacts with Iron to form an Iron chloride barrier under any ZDDP or other AW additives. Also very good cleaner/solvent, and friction reducer

1/4% 1, 4 para-Dichlorobenzene
- EP agent as it interacts with Iron to form an Iron chloride barrier under any ZDDP or other AW additives. Also very good cleaner/solvent, and friction reducer

Oil of wintergreen - for the scent
- Not just for the cent, is also a cleaner. may aid lubricity.

Red Dye - for the color

So from the perspective of our use, it's basically 70% mineral oil and 30% solvent (paint thinner). Nothing special.

Hi,
Well....I think MMO has always been used for its cleaning ability,MIXED with regular dino motor oil. Which is not a bad thing!

I had an old gentleman tell me one time many years ago that he used it on his knees and elbows for arthritis. He was always pretty truthful with me so I tend to believe him. Who knows, in his mind it might have worked.

Is anyone else using MMO?

Yes, a 50:50 mix of pure pine tar turpentine and MMO. Also the same ratio of Turpentine and ATF
A friend in CA put me onto it and I cleaned a 74 Sharps that I had cleaning problems from day one. After brushing and patching, let a patch soak overnight and the next day the bore was clean as a whistle.

The 50:50 mix of either is a good leader remover also

imo hoppes is a pretty ineffective bore cleaner.

Plus one on that. Hoppes #9 containing Nitro-benzene was a good product, but Nitro-benzene was removed from the formula in 1982 or 1985. My supply lasted until the mid-90's.
