hey i took off my head to get a mild port and polish. as i looked at my piston, i saw that they had some carbon build up, and i wanted to clean them up. but don't know how and don't want to hurt the pistons. whats the best way. this is a 96 itr engine in my 96 civic. thanks

 

carb cleaner and a stiff plastic bristle brush.

 

^ Yeap.
