Carbon cleaner?

[SilverbulletMAG]

For strictly carbon, I am a big fan of C4. For copper fouling I go with Sweets and for light cleaning/routine stuff, good ole Hoppes.

START YOUR CLEANING ROUTINE WITH 2 WET PATCHES OF A DECENT CARBON CLEANER.
sea foam is about the best and not over priced as a "gun cleaner".

C4 boretech removed the carbon ring in my 204 fairly easily
