I searched for this but couldnt find anything. How can i clean the faces of my pistons with the head off? I tried gasoline but it didnt do much and carb cleaner does even less.

 

very soft brass wire brush wheel in a hand held drill.

 

I soaked them in wd40 and the grime washed off. thanks.

 

Bringing this thread back. Is it safe to clean pistons by soaking them in something, such as WD40 like ernie did? Should I stay away from anything? Thanks!

 

yeah, WD40 won't hurt anything.

 

You think simple green with an sos pad(The finner type)would also work?

 

I would say it would work, but I would pull the pistons out before doing anything other than spraying on a solvent and wiping it off w/ a rag.

I would be afraid of some of the scratchings frmo the wire brush or abrasive surface getting down into the ring lands...at least w/ the pistons out, you could wash everything off afterwards.

I've heard of some VW guys revvin the motor up and slowly pouring in a cup of water; the water turns to steam when combusted turns to steam and cleans the pistons....not to be tried at home, though....
