I am looking at dyna coating a few rifle barrels and I used Wipe Out patch out to clean. I cleaned for a week with a nylon brush and let it sit in the barrels for 24 to 36 hrs. A friend of mine gave me a small bottle of Slip 2000 Carbon Killer and a small bottle of Eliminator. Has anybody every used Carbon Killer and then brushed the bore and not got a dirty patch? The same with Eliminator have you ever used it and let it sit for 15 minutes and not got a blue patch? I don't have a bore scope but I sure thought my barrels were clean with wipeout. For kicks I used slip carbon killer and brushed the bore and was really surprised to see a dirty patch. Then after two sessions with the slip I ran a couple of patches with eliminator thru and yep blue patches. I just want to know if anybody has ever used this and not seen these results.
