Did you see the job Pinesole does on carbs ? I wonder how it would work on pistons ?
Purple Power. But you have to check on them. You cannot just leave them in there.
Buy a Gal of WD40 shake it up good and put the piston up side down in a small bowl over night, the next day you can just wipe off all the carbon and clean out the ring grooves. it's all I use anymore. It works great and doesn't hurt the piston.
Diesel fuel works good to soak them in and start loosening up and dissolving the carbon.
Need to brush them down once in a while to help them along.

I haven't tryed simple green in my ultrasonic cleaner yet but I do want to try it.
Be careful with cleaners like simple green and purple power. They are both corrosive to aluminum. That's why I recommended checking on them in purple power and not just letting them sit.
Automatic dishwater detergent will pit aluminum too.
That why I really haven't used it yet, Thanks on the heads up.
I think its the lye. Strong stuff

Believe it or not, Easy off oven cleaner works great. Don't just spray it on and leave it overnight, spray it on, wait 15 minutes, and hose it down. Do this 2 or 3 times, and dry them. Air at 135+ PSI, and a gentle oven. Make sure you rinse it all off, and dry it fully with gentle heat.

I had a snow blower crankshaft with aluminum from a burned up connecting rod stuck all over it. I soaked it in Drain cleaner (Lye) for two hours or so and all the aluminum dissolved off it leaving the crank mint. As said lye will kill those pistons. wd40 get my vote.

WD-40.
I use Simple Green full strength in a Lowes bucket, but like Rob said take them out and rinse, then air dry.

Dont soak them so long you ruin the ring grooves. Enlarged grooves, the rings wont seal, pistons ruined.
THey will turn your carburetors black if you don't get the correct stuff.
Nice HP 273 pistone right there!
I use simple green mixed with water and boil them in an old crock-pot.
Check them every couple of hrs, do not leave them in there for a long time.
