If you want or need to clean the bolt and carrier there are two main methods:

One is to use a carbon removal liquid cleaner like Slip 2000 Carbon Killer.
This is a human and gun safe cleaner that, along with a little brushing removes most of the fouling.

The second method is mechanical. This method uses a special scraper tool that removes the carbon from the tail of the bolt, from the inside of the carrier, and from the front of the flange on the firing pin.

The best are the CAT 4 tool and the Otis BONE tool:

I haven't tried the Otis BONE tool but I use the CAT 4 with excellent results.

I regularly use Slip 2000 Carbon Killer on the muzzle brake of my AK-74.
