Sodium Bicarbonate Blasting 

Sodium Bicarbonate Blasting or soda blast for short is a process in which sodium bicarbonate is applied against a surface using compressed air. An early use was to restore the Statue of Liberty in the late 1980s.

Soda blasting 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, masony cleaning and restoration, soot remediation, boat hull cleaning and for food processing facilities and equipment.
