A cardboard box makes a good holder. More aggressive media would quickly eat
away the box, but the gentler soda goes easy on it. At 80 psi it removes even the
cured enamel. We had to bare down a bit to get the paint out of the tiny cracks and
corners, but it removed it all.
The carb — very nasty and dirty — had a lot of hard-to-reach surfaces and was
made of soft metal. The soda blaster quickly removed the buildup and didn’t scar
the metal.

Results. The hardened enamel paint was
completely removed except for one tiny
spec in the Philips screw slot on the left
screw. We didn’t see it at the time. A few
more seconds of concentrated blasting
would have removed it.

We wouldn’t want to blast the carb with harsh media, as the soda
cleaned the soft castings down to the metal, without injuring the surface
or using harsh chemicals. The dichromate plating used on steel rods
and other parts was also preserved.
Even the tag came clean, and without the pitting that more abrasive
media would cause.
