I wipe them off with a rag soaked in mineral spirits or penetrator. If there is some heavily crusted build up on top I may hit it with a putty knife first.
-
Soak em overnight in Simple Green. Works great and no caustic crap to breath
-
Just wondering something. Never tried it. But I have a brass cleaner tumbler for reloading. I wonder what a piston would be like in one? It just vibrates and rotates them around.
Cant remember if I user walnut media in tumbler or what, been awhile.
Good idea on simple green I still havent used the stuff to know.

I usually give them a soaking in a coffee can full of kerosine for a day then brush the crud off .Several I put in a coffee can.metal not plastic with strong detergent and water and boiled it on the gas grill .Works but it's getting hard to find a metal coffee can these days. I doubt if plastic would be a grand plan .

Kev, be interesting to throw a piston and some dry moly coating along with some shot and see if the impingement from the shot hitting the piston transfers the moly as is done with bullets
-
You might want to use an old pin in the piston to protect the pin bore?
-
Be a good idea. Might try it out and see if the moly sticks to the aluminum. Gotta be better than the moly spray paint on the Chinese AM pistons! Lol
-
Interesting Adam. Never done anything with moly and bullets here. Keep us updated.
-
The moly for bullets is pretty sticky, it'll even "season" the rifle bore with moly.
I got a bunch of 6mm 115gr D-Tacs to test out that were molyd and since my rifle wasn't going to shoot moly forever I didn't want to shoot them then have to clean it all out so I stuck the bullets in the tumbler and all the moly came off pretty easy. I'm not sure it would stay on a piston for more then a few minutes...???

Throw a piston in the tumbler with some bullets and see how it coats the piston!!!!
