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.

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...???
