Soda blasting uses sodium bicarbonate to remove paint, grease and stains from steel, aluminum, wood, sheet metal and many other surfaces. The soda blaster uses sodium bicarbonate (baking soda) instead of sand which is also commonly used in a sand blaster to remove stains. The benefit of using soda blasting is that the sodium bicarbonate is environmentally safe, relatively affordable and washes away easily with water. If you have a sand blaster, you should be able to use it for soda blasting.
