Abrasive blasting is the projection at a surface of a suspended particulate in a pressurized air or water stream for the purpose of removing a coating or contaminant, or other alteration of that surface in some way.
One of the most important differences between abrasive blasting with sodium bicarbonate (baking soda) versus abrasive blasting with any other abrasive medias are that baking soda’s attributes allow it to remove contaminants without damaging the underlying substrate.
Sodium bicarbonate is the ideal abrasive blasting media for the removal of oil and grease.
