I want to blast clean some used engine pistons (alloy), with minimal
base material removal. What can I use as the blasting medium, or are
they better vapour blasted in some way? Thanks.

Thanks for that, worked fine in a friends machine with that stuff in it,
and some medium duly ordered. Cheers.

I have some wankel rotors and housings that sure have some stubborn
stuff on them. I'm about ready buy that $99 HF cabinet and some walnut
shells.
