Sodablasting is a process where sodium bicarbonate is applied against a surface using compressed air. An early use was to restore the Statue of Liberty in the late 1980s.[1]
Sodablasting is a non-destructive method for many applications in cleaning, paint stripping, automotive restoration, industrial equipment maintenance, rust removal, graffiti removal, molecular steel passivation against rust, oil removal by saponification and translocation, masonry cleaning and restoration, soot remediation, boat hull cleaning, food processing facilities and equipment.

Applications
It can be used for cleaning cars, boat hulls, masonry, and food processing equipment. Sodablasting can also be used to remove graffiti[2] and to clean structural steel.
One paint manufacturer recommends against using their automotive epoxy primer over soda blasted substrates.[3] A refinish specialist from a major vehicle manufacturer does not recommend soda blasting prior to automotive refinishing.[4]
Tools
A Sodablaster is a self contained system that includes a blast generator, high pressure compressed air, moisture decontamination system, blast hose, and a blast nozzle that is capable of handling dry or wet blasting material. The blast nozzle should be tungsten carbide and in Sodablasting applications is not a typical wear part.
The blasting material consists of formulated sodium bicarbonate (also known as baking soda). Blasting soda is an extremely friable material that has micro fragmentation on impact, literally exploding away surface materials without damage to the substrate.
A Sodablaster differs from a sand blaster in that the Sodablaster is not gravity-fed, meaning it will not come out of the bottom of the pressure vessel.[citation needed]
