Soda Blasting is the use of compressed air to force sodium bicarbonate (baking soda) at a solid surface in order to remove contaminates from the surface. From the force of the pressure-driven contact, contaminates on the substrate are blown away with minimal impact on the substrate itself.
Soda blasting is used to clean paint, grease, and oil from surfaces such as:
- Sheet Metal
Soda blasting holds several advantages over its blasting cousins, such as sand blasting. Soda blasting:
- Helps absorb odors
- Is highly efficient for use in small spaces and gets into tiny crevices easily for complete removal of contaminates
- Functions as a degreaser as well as a medium for contaminate removal
- Has the ability to clean surfaces such as sheet metal without risk of warping the metal
- Is a cooler temperature cleaning method as it does not produce heat build-up during cleaning
- Acts as a gentle abrasive that does not pit the surfaces it cleans
Dry ice blasting:
Dry ice blasting is the use of solid pellets of carbon dioxide blasted at a surface to be cleaned. The pellets are forced at the surface using pressurized air and the kinetic energy produced results in the removal of surface contaminates.
Dry ice blasting is a highly efficient method of cleaning a large number of surfaces. Applications for dry ice blasting include but are not limited to the following:
- Cleaning turbines and generators
- Cleaning electronic equipment, including circuit boards
- Clean up of fire, soot, and smoke damage
- Elimination of mildew, spores, and mold
- Paint stripping
- Cleaning of ink, particularly in the printing industry
The benefits of dry ice blasting over other types of blasting, such as sand blasting, are numerous.
- Efficiency is heightened with use of this process. Since carbon dioxide sublimates at room temperature, it substantially reduces clean up after use.
- Safety is greatly weighted in favor of dry ice blasting. No harmful vapors are produced, thus eliminating risks for employees who may be sensitive to harsh chemicals in other cleaning methods.
- Dry ice blasting allows for easy preservation of surfaces. It is non-abrasive, attacking only the contaminant and leaving the surface itself unmarred.
- The Environmental Protection Agency (EPA), Food and Drug Administration (FDA), and the United States Department of Agriculture (USDA) have approved this cleaning method not only for general use, but also for use on food processing equipment.
