I've gotten some Carbon Killer and tried it in the AR-15 last night. It wasn't that bad so really couldn't tell much about it yet.

MZ5,

Thanks for that information. Must be carbon is simply suspended in it, so the base liquid is unchanged by picking it up.

I used to have an old fashioned hand-cranked centrifuge. I should see if I can find what I did with it and try using it to draw the solids out. Be a little slow, at just two test-tubes worth at a time, but interesting to find out anyway.

"First contemplation of the problems of Interior Ballistics gives the impression that they should yield rather easily to relatively simple methods of analysis. Further study shows the subject to be of almost unbelievable complexity." Homer Powley

I deleted one line from previous reply because while doing some research, I found I was using the Deatons' Deep Clean in a way you're not suppose to. I overlooked a sentence on his home page"NOT TO BE LEFT IN THE BARREL FOR MORE THAN 15 MINUTES". When I ordered it, I never really read his home page and went straight to the product and didn't see the phrase on the product page. Glad I've only used it a couple of times in two barrel and left it to soak. I guess it's has a high concentration of ammonia like Sweets 7.62. I think it's more harmful to stainless than CS but regardless, I won't be letting them soak with Deatons' anymore.

I will probably still be using it at the range for an all in one cleaner because it's the best I've come across to date. I have gotten some of the Slip 2000 Carbon Killer and Gun Lube to see how it works.

What I use depends on which gun I'm cleaning and the condition it is in. I do believe it is possible to over-clean guns and do more harm than good.

What I have had great success with is G-96 Gun Treatment. I won't say that it is the best lubricant or bore cleaner in the world, but it is first rate when it comes to protecting your blued finish. It will absolutely protect against rust and gives the gun a great appearance.

G-96 also is great stuff for cleaning hard to get at areas, such as the interior of actions or the inside surfaces of autoloading pistol slides. I'd say I've been using this product at least 40 years and am still impressed with how well it works. I have not seen anything better.

Copper solvent or powder solvent which do you use first?

If using single solvents, I do carbon first, then copper, but if I shot a lot of rounds, I do that at least twice and then do another carbon. Then I check it to see if I see any copper. Sometimes they will build in layers and you usually have to get the carbon dust off first to see the copper. After getting the copper, sometimes you can have another layer of carbon under it. In extreme cases, I've seen several layers of each in rifles that were shot large numbers of times over an extended period and never properly cleaned.

I find on a lot of barrels there is a happy medium you have to learn. Clean one too clean, and it keeps coppers fowling. Don't clean it enough and it affects accuracy. Some barrels like to be bright metal clean but I find most shoot better if when I make a couple strokes with a tight fitting dry patch through it and it comes out a medium gray, and leave it. Depending on the solvent used, I may or may not run an oil patch through it. If I do, I dry it back out with a couple of patches.

Thanks.....

Everybody has there own way. I use the heck out of bore snakes!! But for heavy cleaning with bolt action rifles I remove the stock. Blast everything with CLP including bore. Wipe/scrub everything, run snake through bore. If I have a copper issue or nasty stuff that the snake is not removing then I bust out the solvents patches and one peace cleaning rod. Several of my firearms don't get shot a lot so I grease them down with with something like RIG. I also grease the bore. I remove grease from bore prior to shooting. I'm lazy so I just wipe down the outside and go shooting. Clean and 're grease store. For my guns I use all the time I just oil after cleaning. Like I said everybody has there way. I use to take hours and detail the crud outta my guns. Now I just clean them. Still no problems but I don't own precision rifles or zillion dollar guns.
