I want to sell some trw pistons I have from 454. They have some carbon deposit on them. How do I clean it off? Do I use sand paper or is it bad to do? Any compound I can buy?

 

i use pee.

but degreaser should work just fine.

 

Wire brush.

 

hot tank

 

bad idea from what I read

 

anything I can do myself?

 

I've used it before with no problems. Just don't gouge the fuck out of the piston top.

 

werd, soak them in some degreaser and then polish the shit out of them

 

soaked in a home made parts tank...get some mineral spirits and a bucket...let them soak for a while and then with a stiff brissle NON metal brush scrub the carbon off, followed by another soak and the final shit will come off with a toothbrush and some towels...it takes a bit longer than the hot tank but works wonders.

 

A wire brush is going to leave a coarse surface for crap to stick too. Use degreaser and a nylon brush I would say. I've never done it, but maybe even use metal polish on the tops to make 'em real smooth so stuff won't stick to 'em.
