What Is Soda Blasting?
Soda is a new age, non-destructive media. Soda blasting is the application of sodium bicarbonate to surfaces with compressed air. Sodium bicarbonate is a chemical compound with the formula NaHCO₃. This chemical is a crystalline white solid but often appears as a fine powder. It has a slightly salty alkaline taste, resembling that of washing soda.
The History of Soda Blasting
In 1972, the Statue of Liberty required a thorough clean. There was a great deal of concern regarding the possibility of contamination to the surrounding water and damage to the statue itself. Because the Statue of Liberty is made of copper, sandblasting was considered much too harsh of an abrasive that would result in surface damage. Thus, soda blasting was born. Because soda is a water-soluble media, cleanup was minimal. Since then, soda blasting has changed the sandblasting industry altogether.
Uses and Benefits of Soda Blasting
Because soda blasting is gentle and environmentally friendly, this method is helpful for a multitude of industries and surfaces. Some of these industries include:
The Marine Industry
Soda blasting is excellent for removing paint and barnacles off of the bottom of boats without damaging the gel coat.
The Auto Industry
Soda blasting works wonderfully on thin metals because it will not warp or produce heat while blasting. When rebuilding or restoring an engine, soda blasting can also clean blocks, heads, pistons, crankshafts, or internal engine parts without scoring cylinders or bearings.
When graffiti is on glass or soft surfaces, soda blasting removes graffiti without scarring or damage.
The Printing Industry
Soda blasting removes ink buildup on printing presses and anilox rollers without profiling or etching the surface.
After fire damage, some structures can be salvaged with soda blasting. The framing of a burnt house can be soda blasted to remove soot and eliminate the pungent odor left after a fire.
Soda blasting is non-toxic, making it ideal for cleaning baked-on buildup on food processing equipment.
