Unless and until the carbon accumulates to a point that it makes a significant restriction to the gas flow......they don't need to be cleaned. The hot fast gasses flowing through should be enough to keep the passages open. The carbon that might accumulate on the flat surfaces should not cause any problem until it gets REALLY bad.
AND....if the engine makes enough carbon to plug the muffler/spark arrestor quickly then you likely have something wrong with the engine. 2-cycle engines are bad about that; others should not be.
