I just got done rebuilding a Saturn S series engine and the pistons were very carboned up. Both the tops and the ring grooves had alot of carbon build up. I took one of the pistons and soaked it in lacuqer thinner and it removed some of the carbon but not all. I got out my HF ultrasonic cleaner and bought some Simple Green HD pro from Home Depot and after 2 cycles (4.5 minutes each) they came out looking like new. I also did all the valve train parts this way and they all came out like new and best of all no scrubbing!
