Media – Baking Soda

Armex logoESCA is an original ARMEX dealer and has been involved with soda blasting since the mid-1980’s. We know quite a bit about soda blasting and are happy to share our knowledge below. Please feel free to call if you have further questions regarding soda blasting and its capabilities.

 

History of Soda Blast MediaCarbonart

Sodium Bicarbonate (Baking Soda) is classified as a soft abrasive (2.5 on Mohs hardness scale), and was originally used during the restoration of the Statue of Liberty. The Soda formulas we carry are unique and much different than what is found in your refrigerator. They are all engineered and processed specifically for soda blasting, ensuring an even and consistent flow throughout a project.

No Damage Blast Media

Soda media is soft and will not create a profile, generate heat, or inflict any damage on soft metals, polished stone and masonry, rubber trim, glass, etc. Most Corvettes are restored today using baking soda media, as it takes the paint off but leaves the fiberglass behind. Many newer Boat Bottoms are stripped today using baking soda media as well because it effectively removes marine paint without harming the gel coat. Because Soda is water soluble, it also prevents “embedment” damage that traditional sandblasting methods can cause.

Using Soda for Preservation and Restoration Projects…

Baking Soda is the softest cleaning media available, which makes it an ideal restoration choice when working on certain types of old and delicate structures and materials. We recently performed a trial in Washington DC which involved cleaning an 80 year old glass and ornamental aluminum entryway. Baking Soda was the only choice – it has the unique ability to clean effectively without etching or frosting window glass.

Baking Soda is also the only media that can clean polished stone without harming the polish. Until recently, this was not possible. However, ESCA Special Cleaning machines now provide the ability to perform delicate cleaning tasks without harming the integrity of the original surface.  Do you have non-polished stone to clean?  Then we would recommend using Calcium Carbonate instead.

We stock and sell all different formula types and grit sizes. Some of our formulas contain flow aids – needed if supply air is moist or your working environment is humid. Other formulas we carry are designed for specific applications, such as marine paint removal or rust and oxidation removal (composed from a blend of soda and aluminum oxide).

 

How does soda media work?

Soda Blasting yields great results because the soda crystal is sharp and essentially explodes upon surface impact. This shattering effect ensures Soda Blasting’s effectiveness in removing tough coatings, paints, and heavy duty grease and soil conditions from both delicate and sturdy substrates.

Eco and Operator-friendly Blasting Media

Baking Soda is safe to use and handle, and can help companies comply with many of their green initiatives. Baking Soda is all-natural, water soluble, non-sparking, inorganic, silica-free, non-toxic and non-hazardous, as defined by the EPA and OSHA. Sodium Bicarbonate is also classified as an A-1 cleaner, making it suitable for use in any FDA or USDA-regulated facility. ARMEX contains no solvents or caustic ingredients, providing a chemical-free alternative that simplifies and reduces waste disposal costs.

Applications of Soda Media

Hundreds of applications exist  and are still currently being discovered for soda media. The most popular uses for Soda Blasting we run across on a daily basis include disaster recovery, fire damage restoration, smoke damage restoration, mold remediation, parts remanufacturing and cleaning, automotive and boat depainting, food processing, building restoration, graffiti removal, non-destructive testing prep, and industrial maintenance.
