I wasn't being sarcastic, I was trying to understand what part you were referring to. Now i understand its the inside of the bolt carrier. There are several methods for cleaning this, from special tools you can buy, to scraping it with a brass scraper or other similar tool, to soaking the carrier in chemicals, etc. Many have had good results by soaking the carrier in mineral spirits. Slip 2000 isn't a very powerful cleaner by itself, but with some elbow grease works well enough. This area does not need to be spotless, I just try to remove the larger chunks.
ETA: I was thinking regular Slip 2000 (CLP), not the carbon killer. The carbon killer is stronger.
