Dirty pistons

Hello I hope everyone is doing well. I am putting my car back together after doing some work on it. It sat a while with the valve cover off. I shined a light down into the spark plug hole to see if the pistons are dirty before putting new spark plugs in. They are pretty dirty. Is there a way I can clean the top of the pistons off without taking everything apart?
 
To echo what Awa said, this motor is a turbo DI motor and tends to run pretty "dirty" in comparison to a port injected motor.

Soot on the tail pipes and back hatch are a part of life with this car as well as carbon build up on valves and other engine components.
 
If your saying that stuff fell in the open holes you can try to vacuum. You can tape a small diameter hose to the end of your shop vac so that you can fit something into the spark plug hole. If your just worried about black carbon that's just the way it is
