Soda Blasting

Providing Baking Soda Blasting in Maryland

What is Baking Soda Blasting?

Baking Soda blasting is the latest technology to safely strip paint and clean most any surface. The soda blaster uses compressed air to deliver sodium bicarbonate based media (baking soda) onto the surface to be cleaned. While at the outset this seems similar to sandblasting, all similarities quickly fade once you understand the process. Sand is a hard, heavy material that can wreak havoc on many substrates. It will pit and warp metal, tear up rubber & plastic and etch glass. Soda blasting has none of that. A properly formulated soda blasting media is made of Sodium Bicarbonate that is manufactured to be in a consistent, large crystal size. When it strikes the material you are soda blasting the crystal explodes outward and the explosion is the force that strips your target of grease, paint, light or new surface rust, mold, dirt, whatever it is you are removing.

It is difficult to tell someone about soda blasting without using the phrase “the best part.” Why? Because there are so many advantages to soda blasting they are all “the best part!” You want to say:

  • The Best Part about soda blasting is it doesn’t harm the substrate. No metal warping, no flash rust, no more masking of glass, chrome and rubber! What a time saver!
  • The Best Part about soda blasting is the easy clean up, the media is water-soluble.
  • The Best Part about soda blasting is how it is environmentally friendly! It’s baking soda! Non-toxic, non-flammable, non-hazardous, FDA approved and you can make biscuits with it!
  • The Best Part about soda blasting is how versatile it is! It can be used in so many applications!

The cleaning effectiveness of 100% pure Baking Soda Blasting Media is a direct result of its physical properties. These qualities allow the media to be used in a wide variety of applications with superior results.

Soda Blasting Advantages

There are many advantages to soda blasting over other forms of abrasive blasting and we are happy to point them out. Not only is the cutting action different (and superior) to other methods, blasting with baking soda has advantages that begin before you even begin blasting and last after you have packed up and left the job site.

Baking Soda Blasting Facts

In the past, the only way you could remove paint or some other unsightly material from a contaminated surface, was to either chip it off, sand blast it, use harsh chemicals, sand it until your arm fell off or your equipment failed. In most cases, after these time consuming, or hazardous methods are discarded, the final solution was just to paint over it and hope no one noticed.

In the images below you can see that baking soda will leave a smooth original sheet metal finish.

After Baking Soda Blasting

What is the process that you should follow to cleanse the surface after soda blasting and before coatings re-application? We get this type of inquiry quite often and we have spent considerable time and effort to provide you with the most up-to-date policies, procedures and products available.

Abrasive Blasting

In response to customer requests, we have added abrasive crushed glass and coal slag blast medias to our blasting line-up. Although baking soda blasting (sodium bicarbonate) remains in our blast media offering, we now have the capabilities to “shoot” these popular media. Crushed glass blast media is a light duty abrasive and is great for paint removal, rust removal and sometimes can be used to strip furniture.

Crushed Glass Blast Media (an abrasive blast media)

Eco and Operator-friendly Blasting Media:
100% recycled crushed glass eliminates the health risk of airborne carcinogens. It is non-hazardous, non-toxic and completely inert and is safe to use around water. Glass dust is classified by OSHA/NIOSH as only “nuisance” dust because it contains less than 1% free silica. Crushed glass is also virtually free of any of the OSHA identified Heavy/Toxic Metals associated with some slags and some other mineral abrasives. Lastly, since glass is translucent, visibility and productivity are significantly improved when compared to a blast environment using traditional hard abrasives.

How Can Glass be Silica-free?
Recycled bottle glass is chemically known as Amorphous Aluminosilicate. Free-silica is commonly found in traditional blasting sand (silica-sand) and other hard abrasive sandblasting medias. Silica-sand dust in its natural state has an “open” crystalline structure that has the capability of sticking to lung tissues. When this happens, the likelihood of developing a serious respiratory disease called Silicosis increases. Because our recycled glass blast media is amorphous, its crystalline structure is “closed,” which makes it impossible to physically stick to human lung tissue. When a person is exposed to amorphous glass fines or dust, the body will expel the dust as it would any other type of natural dirt.

Benefits of Glass Blasting:
In addition to worker safety benefits, crushed glass delivers a natural, whiter metal finish than many other sandblasting abrasives, and significantly decreases embedment issues—up to 5 times less than slag blast media. Glass works great for removing thick, tough coatings and in numerous surface preparation applications—glass can create a profile of up to 4 mils on hardened steel. Glass is versatile and can be used as a dry blasting media or combined with water for use in slurry blasting machines. Glass blasting leaves an etched white metal finish comparable to an 80 grit sandpaper.


Qualified for Use:
Crushed glass has been added to the qualified products list by the US Navy. Crushed glass is qualified under MIL-A-22262-B, Amendment 2–Abrasive Blasting Media for ship hull blast cleaning. Based on toxicological safety evaluations by the Naval Environmental Health Center (NEHC), Crushed Glass Grit can be safely used for its intended purpose. The addition of crushed glass to QPL includes 12-30 mesh (CBM 1230); and 30-70 mesh, (CBM 3070).
