Scraping the carbon fouling off the parts is not enough and you need some strong solvent to make your life easier.

There are many carbon removal solvents on the market, and the best one with fast carbon breakdown and minimum smell is the Break Free CLP. You can try others but you will always come back to this one.

Removing the gas tube is definitely annoying if you don't have a dedicated gunsmith workbench or the patience to do it.

The easiest way is to buy a dedicated gas tube cleaning kit with brushes that you can stick through the gas tube, or you can buy some cheap gas tube pipe cleaners here.

They have wire core in them with highly absorbent cotton bristle carriers to scrape all the junk out of your gas tube.

This is a very popular questions for people who are concerned with carbon build ups could affect accuracy. This is a very valid point for any precision shooters.

In that case, when accuracy is important, please clean your gun every 50 rounds.

If you're trigger happy CQB tactical shooters who only care about effective hits and reliable rifle cycling, its recommended to clean your AR every 1000 to 2000 rounds.

Definitely take the time to clean it around the 2000 round counts.

Final Thoughts

Cleaning critical internal AR15 components and accessories are important to keep the weapon away from any major malfunction. Carbon build up is the number 1 thing you need to pay attention to.

We recommend the Real AVID Carbon Boss Multi Tool for cleaning a BCG, Real AVID Bore Boss for cleaning the barrel along with the Break Free Carbon Removal CLP.
