Cleaning pistons

I always taped over the ring lands when bead blasting and blasted the *** out of the skirts
used walnut hell blast on the ring lands\
When bead blasting use NEW bead or have a separate blaster that has never seen iron or steel
using dirty blast does ruin pistons
Too bad you cant get the chlorinated chem dip any more
you know- the stuff that would take your skin off

When I was still in high school, I worked for a local mom and pop machine shop that was opened in 1957. The owner opened it upon his return from the Navy. He had a 55 gallon barrel with 35 gallons of carbon-tetra-chloride in it. That stuff would clean the nastiest carburetor you ever saw in an hour. It was some bad stuff.
