Clean piston top and lands? 74/360

I just soda blasted a ford carb thru every passage and the entire outside. I am sold on soda. Removes all varnish, carbon, rust, paint and grease, does not phase the aluminum. The rust was very light on some butterflies and levers, was totally blasted to bare metal.

Also, I have found that soaking alum carbs submerged in pinesol is amazing on carbon and varnish. We soaked another ford carb in pinesol and it came out spotless after 3 days. So, I may do this too on some pistons before soda blasting.
