A soda blaster is similar in design to the pressure pot sandblaster except it’s made specifically for the softer abrasives such as baking soda. The baking soda abrasive is also better known as sodium bicarbonate in the sandblasting industry.

The sodium bicarbonate is not only soft, but it is also fairly fine in grit size. The benefits to using a soda blaster and its sodium bicarbonate abrasive, is it won’t cause pitting abrasion on the substrate and it will not warp sheet metal when blasting.

Harder abrasives like garnet & aluminum oxide are known to roughen up metals being blasted and sometimes (especially with courser grits) can cause sheet metal to warp due to the heat that it builds up when striking the surface.

Soda blasting is typically used for the materials listed below:

• Aluminum
• Thin sheet metal
• Pot metal
• Plastics
• other soft metals

Some typical components that people soda blast are:

• Carburetor components
• Intake manifolds
• Car body sheet metal
