Default Best way to clean piston!!!!

Just wondering whats the best way to clean the piston while I'm doing new bearings and ring. The piston got that yellow, brown, burnt look to it from the heat. I just didn't want to scratch it all up and ruin it. Any info would be appreciated.

I think I heard of people soaking it in anti-freeze.

Carb cleaner from an auto parts store. Comes in an aerosol can. Dissolves all that black burnt looking stuff with just a rag and some elbow grease.

Four days and all we can come up with is antifreeze and polish? Good ideas, but here are some traditional methods of cleaning pistons and engine part I have found...

Steam ( turn your home boiler into a steam cleaner Lol I did) ( I have one trunk for bending wood and one for saute' ing engine parts on a rack with a nozzle)

Ultrasonic ( get her done)

Wallnutshells or Soda blasting, ( or some other non abrasive blaster) can get a cheap blaster and bag of Soda for 40$ at harbor freight...

Dishwasher ( dont let the wife know)

Scraper

Others:
Hot lye ( sodium hydroxide) ( dont use on non-ferrous parts or parts with important tolorences ) ( caustic)

Coka-Cola ( mildly acidic) ( still not the best and sticky)


leave it in front of a Nascar nut ( will be clean in under an hour... ), wait and return to new clean piston.....
