SodaBlast - the revolutionary new process that blast-strips paint, grease, rust and other build-up without scouring or pitting the base material.How It Works:Specially formulated sodium bicarbonate (baking soda) is the secret. High-pressure compressed air fires the soda at the surface. The sodium bicarbonate granules shatter into fine particles on impact which blasts away the unwanted material.Restored to its original smooth condition the base material is ready for repainting or immediate reuse. No pitting, no scouring.
