If you’re considering soda blasting, there are a number of factors to keep in mind. There are a number of benefits to soda washing, and the process can yield results that will protect the surfaces of your walls or vehicle. Here are some of the advantages.

Cleaning and De-Coating

Soda blasting allows you to both clean and de-coat in one step. If you use standard abrasive blasting for cleaning, there is a chance that you could contaminate the surface with oil or grease while removing the coating. Recycled abrasives make this problem worse. A pure sodium bicarbonate blast will effectively clean and de-coat in just one step.

No Pre-Cleaning

If the surface to be cleaned is covered with salt, carbon or grease, traditional cleaning methods require cleansing of the coating before pressure washing. This is so that the surface contaminants will not go through the coating and into the surface of the item you’re cleaning, which can ruin both the coating and surface. With soda blasting, pre-cleaning isn’t required, which keeps the surface and coating intact.

Cutting Action

Sodium bicarbonate blasting offers the uniqueness of cleaning with baking soda. The softness of the crystals, which are a 2.4 on the Mohs hardness scale and a friable nature, which has a cutting effect on stains that won’t damage surfaces. For example, you can use soda blasting to remove thick coatings from glass without etching the glass. If soda blasting is done correctly, even delicate fabrics can be cleaned without damage.

No Re-Profiling

If you’re using sand blasting for steel, there’s no need to re-profile unless there has been corrosion. When the coating is removed from a metal surface, the anchor pattern under is reveals, so re-profiling isn’t necessary.

Solid Waste Reduction

Pure sodium bicarbonate can easily be dissolved in fresh water. When the substances is dissolved and filters out contaminants, the solution can be disposed of in open waterways or POTW treatment systems if you have the appropriate discharge permits. The volume of waste is reduced to less than 5% of the original volume, which makes soda blasting more environmentally friendly.

Rust Prevention

When baking soda is on a ferrous metal surface, no rust will form. In order for rust to develop, moisture has to be on an acidic surface. In most situations free moisture mixed with the carbon dioxide in the atmosphere and form carbonic acid. The acid releases a ferrous or metal ion and this mixed with oxygen to form rust. Pure sodium bicarbonate blasting buffers the acids that may form during cleaning, and keeps free metal ions from being released, which is how rust is prevented.

It’s also important to note that soda blasting can reduce the cost of cleanup if you’re using this method of cleaning for a large job. Soda blasting does the same level of work as sand blasting, while producing around 1/7 of the waste volume that sand blasting does. The net balance for the total cost per square foot may be the same, but you’ll still end up saving money since you won’t have to pay as much for cleanup after the soda blasting job is completed.
