Thanks to everyone that weighed-in on the ultrasonic cleaner question that
I posted a few days ago. If I go for the larger unit at Vervor, I'll let
you know how it works with a follow-up post. I'm still a little skeptical
if it can remove carbon in a combustion chamber or piston ring groove but
it might be worth a try. Possibly use the ultrasonic tank for the softer
deposits and if the carbon is still there, hit it with the ground walnut
shells in my blaster. Not a big time saver though at that point.
