Hi Guys. I have just purchased a new Fabarm shotgun. I have noticed that the gun deposits a lot of carbon on the piston. It especially does this on the front of the piston where the gas vent holes from the barrel are. This deposit seems to be rock hard and solvents do have much of an effect on it.
What is the best way of removing it? Brass brush? Any ideas would be more than welcome.

Here is a picture of the piston.

It has aluminium parts in it and plastic as well. So using very aggressive solvents might cause problems.
