CLP doesn't get rid of corrosive salts. If you shoot corrosive ammo, a cleaner for black powder is far superior, even soap and water works better then a oil based cleaner.

I remove my upper (5.45) and pull the nozzle out from the sink and run water down the barrel and gas tube. Then I take a heat gun and get it nice and hot. Then use a straw to squirt a bit of CLP down the gas tube, squirt a bit down the barrel.... compressed air to blow the excess out of the tube and run a bore snake through the barrel.
Rinse out the lower and blow it out, then heat it up to dry it. Clean and lube it. Rinse the BCG real well, dunk it in carbon cutter, then clean it, heat it dry and lube it. When I start shooting it through my can I will rinse it, too. Blow it out and then heat it to 250 or so to boil water out of it. |

I just use hot soapy water to clean my M53 barrel after firing corrosive 8mm. Works great and in the comfort of my own kitchen sink.

I do use corrosive ammo built 1935 for both of my Mausers K98 chambered 7.65
Till now for about 5 years. Barrels are still shiny and good and I still compete with those. 250 to 300 shoots a year. How do I clean? Inmediatelly after shooting with ballistol or regular hopes. Brush. Ballistol or hopes again and swipe as in every gun. Some other friends use gasoline and others use water with soap. I have not noticed any difference between thevthree methods. But cleaning hours or a day later has damaged tje barrel from some friends. |

I shoot corrosive ammo in some mil surp guns.
My process is simple. I heat a tea kettle not all the way to boiling. Just hotter than the tap. I pour it down the barrel with the bolt shut and then again with it open. I let it drip out then I take it to the cleaning bench and clean with Hoppe's and used Ballistol to lube it. My stuff looks the same as when I got them. Very simple. With a semi-auto don't forget to clean the gas tube or piston. |

The deal with corrosive ammo is that anywhere that gas or powder residue touches will have corrosive salts deposited. These will attract moisture and cause rust. The only way to remove these corrosive salts is to dissolve them in water and flush them away.
There's plenty of different methods and cleaning products out there, but as long as you use something water based to flush away the corrosive salts from anywhere where gas or powder residue is deposited, you'll be fine. Just remember that by introducing water based products to the weapon, you're running the risk of causing rust from the water, unless you completely dry all metal (and preferably lightly oil as well). |

I know that hot water and an ammonia based cleaner are what is recommended for mosin nagant cleaning after chooting old surplus ammo. So maybe some windex and a hot rinse.

Extreme corrosion of the brass can cause a case failure and if the ammo was bounced around year after year in the bed box of your truck for example it can change the grain size of the powder and POTENTIALLY cause an over pressure in the chamber among a few other possible issues.

How much of it do you have? Any photos of its condition? Indeed, it's much much better to be cautious and ask questions. It's why the damn forum was created in the first place to ask questions and give answers. IMO, the OP is wiser for knowing his limitations and asking, than anyone here making fun. 
And to the OP, yes, when you say corrosive ammo, that means that the ammunition, no matter how clean and good it is, it was manufactured with mercury or other metallic salts in the primers. They were considered to be more reliable at one point. Usually found in older European and Communist surplus ammo. And while they may not be "salty" to the tongue, (toxic actually...) they are much the same as plain old sodium chloride and will attract moisture in the atmosphere and set up a corrosive reaction with steel. And oils or petroleum/hydrocarbon solvents do not dissolve salts, only water or some other polar solvent (the molecules have charges/poles) will dissolve and wash away the metallic salt primer residue in the bore and anywhere else the fumes from firing get to in the gun. Polar water molecules, and non-polar oil molecules is also behind why oil and water don't mix... As CaptianOverKill says, corroded ammunition can be perfectly fine if it's just a faint wash of green tarnish on the brass etc. but it could be dangerous if it's gone too far in the case causing a blowout. Although usually ammo that corroded, the corrosion may well make the case so rough that it won't cycle, feed, or chamber reliably. However, it's not a hard or fast rule of thumb to go by. Generally, if you can rub it clean with a rag or your your thumb, it's fine. If it's rough or bumpy, chuck it. Lightly tarnished ammunition can be tumbled in the kinds of tumblers ammo reloaders use to polish it up. It's perfectly safe, and in fact much new factory ammo is tumbled as a final step to give it one last polish before boxing and shipping it. And once it's tumbled, you can inspect it for cracks or pits in the brass that would make it unsafe. However, you'd probably need to have several hundred rounds of corroded 5.56 to really make this worth the effort, instead of just buying some new ammo for peace of mind. Europe and the U.S. largely gave up on corrosive metal salt primers by WWII, and there hasn't been any 5.56 corrosive primer ammunition made anywhere. Even the cheap steel case stuff from Russia etc. is all non-corrosive primers. As noted, the Soviets and Chinese and some Middle Eastern countries kept on using corrosive primers out of poverty, or just bureaucratic inertia well into the 1970's and early 80's with 7.62x39 and 5.45x39 ammunition. |

Might break an extractor. Worst case (no pun intended) scenario, you could get a split case and a kaboom. Personally, I'd dispose of it, but not through the muzzle. ETA - if you decide to clean it up, don't use any chemicals or oils on it. |

Wow it's a nearly Identical word, and I have never heard anyone explain that there was a difference between corroded and corrosive, So I took it to being any ammo that had green shit all over the brass. Thanks for clarifying without criticizing me like others for something that sounded the same. I have alot of it that's why It's good for range ammo. |

If it is more than just some tarnish you may want to considered scrapping it. If you do not have a tumbler you could just hit the cases with some steel wool and wipe them with a rag. You do not need to polish them just get the loose stuff off. As for cleaning the gun you may want to spend a little extra time cleaning the chamber but nothing much to worry about. |

I shoot corrosive in bolt guns
As said I use boiling water to dissolve salts, then clean as normal I bought a long necked funnel, heated it to make a bend in it. I can put the end of the funnel in the chamber and pour the water down the barrel. ETA: never mind
