Soda blasting is a trusted form of abrasive blasting that uses baking soda as its abrasive to clean, remove paint, and remove grease, leaving your surface clean and looking like new. Soda blasting is generally considered safer, non-toxic, and more environmentally-friendly than traditional methods like sandblasting, making it the perfect choice for cleaning sensitive surfaces or delicate substrates. In this guide, we will talk about what soda blasting is, applications and uses, soda blasting equipment, soda blasting media, the soda blasting process, and more. Let's get started!

What is Soda Blasting and How Does it Work?

Soda blasting is a form of dry abrasive blasting that uses sodium bicarbonate (also known as "soda" or "baking soda") as the abrasive media. The soda particles are forcibly propelled against a surface using compressed air.

Soda blasting is typically considered a milder form of abrasive blasting.

The Benefits of Soda Blasting

Baking soda is known to be a soft abrasive. It is typically harder than the surface contaminant (coating), but softer than the substrate (material being blasted). One of the most important differences between blasting with sodium bicarbonate (baking soda) - versus blasting with any other abrasive media - is that baking soda’s attributes allow it to remove contaminants without damaging the underlying substrate.

Soda Blasting Before and After

Soft abrasive blasting is excellent for cleaning materials which need to be reused, like food processing equipment, for example. Soda is also water soluble, so eliminating spent media after blasting is as easy as spraying down the equipment, making sure no abrasive remains in critical areas.

Soda Blasting Uses and Applications

If you need to clean or remove coatings efficiently and effectively on a delicate surface – soda blasting is the way to go. You'll most often see soda blasting in cleaning applications because it leaves a smooth surface without any rough texture or anchor profile.

Soda Blasting Uses and Applications

There are quite a few uses for soda blasting. These include:

  • Paint removal
  • Protective coating removal
  • Cleaning in food processing facilities
  • Stripping and cleaning car frames and parts
  • Graffiti removal
  • Oil removal
  • Maritime applications – boat hulls or boat hull cleaning
  • Cleaning carbon, grease and grime from parts
  • Historical restoration
  • Cleaning masonry
  • Wood restoration, stripping, and cleaning
  • Line striping
  • Fire restoration / soot remediation
  • Mold removal and restoration
  • Cleaning rolls in printing presses

Soda Blasting Equipment

The American-made Dustless Blasting Equipment line is one of the best options on the market for soda blasting equipment. Because of the versatile technology, you can switch between dry blasting, wet blasting, and soda blasting applications as needed with the Dustless Blasting pot.

Dustless Blasting Equipment is best for Soda Blasting

You typically need 5 things to get started with soda blasting.

  1. An air compressor that can generate the required CFM for your nozzle side and desired blast pressure.
  2. An Air Cooler and Moisture Separator to prevent the media from clogging or clumping.
  3. A blast pot, blast hose, and a blast nozzle.
  4. Sodium Bicarbonate, or other blast media.
  5. Personal Protective Equipment or "PPE".

The Dustless Blasting mobile trailers are an all-in-one system that you can use for soda blasting, wet blasting and dry blasting applications.

If you already own an air compressor, Dustless Blasting also carries standalone blast pots, Compressor-Ready Carts and Air Drying and Cooling Solutions.

Mobile Blasting Systems vs. Stationary Blast Cabinets

Blasting cabinets are typically designed to recycle abrasives. Unlike other forms of media, soda media is a single-pass media, meaning it cannot be recycled and used again.

In addition, the dust created during the blasting process greatly reduces visibility inside cabinet. However, there are blast cabinet systems specifically designed for blasting soda that address these issues. It's best to have a blast cabinet dedicated to soda basting instead of trying to retrofit a cabinet designed for recycling abrasive.

Soda Blasting Media – Sodium Bicarbonate aka "Baking Soda"

When people talk about abrasive blasting, they often refer to it as "sandblasting" — a general term that doesn't reflect the wide variety of blasting media available today. In reality, there are many different types of media used in abrasive blasting, each with its own properties and ideal applications. These include materials like aluminum oxide, garnet, steel grit, plastic beads, and silicon carbide, among others.

Soda blasting is one such method. It uses sodium bicarbonate — commonly known as baking soda — as the blasting media. Unlike many other abrasives, sodium bicarbonate is a one-time-use media, meaning it cannot be recycled or reused after blasting. This is an important consideration when evaluating cost and media management.

What makes soda blasting unique is its gentle yet effective cleaning action. Sodium bicarbonate can remove contaminants such as grease, paint, mold, and corrosion without damaging the underlying surface. This makes it an ideal choice for delicate materials, soft metals, or projects where preserving the substrate is critical — such as in fire restoration, food processing equipment, or historical preservation.

Soda blasting offers a non-destructive alternative to traditional abrasives, making it a valuable tool for precision cleaning and surface preparation.

Sodium Bicarbonate on MOHS Scale

On the MOHS Scale of hardness (1-10), the sodium bicarbonate particles have an average rating of 2.4. This is less likely to leave a surface profile on the material being blasting and makes it a good choice for delicate substrates. In addition, soda will not leave particle residue embedded on the surface profile and is water soluble.

Soda blasting with sodium bicarbonate can act as a natural rust inhibitor and prevent flash rusting. It can actually leave a coating on the metal that will inhibit rust for a period of time which is certainly an added benefit.

Costs of Soda Blasting

Soda blasting can be more expensive than other blast media. When possible, the best practice is to use equipment that allows the use of a wide variety of abrasives and consider a more affordable abrasive like recycled crushed glass.

Blasting soda or sodium bicarbonate can be purchased from any vendor that sells other types of blasting material or blast media.

While all baking soda is chemically the same, grocery store baking soda is not recommended. Be sure to purchase blast media specifically formulated and manufactured for soda blasting applications from your local abrasive distributor.

Will soda blasting damage plants, grass, or other flora?

While soda is considered non-toxic and environmentally-friendly, you still need to exercise caution when blasting near plant life. It is recommended that containment be set up to prevent the blast media from contacting the plants.

  2. Use Containment - Read Containment and Cleanup Tips for ideas. 
  3. Be aware of OSHA guidelines related to abrasive blasting.

Containment: How to Clean Up After Soda Blasting

Containment and cleanup are important parts of any soda blasting job, especially since sodium bicarbonate is a single-use media that breaks down easily but still requires proper handling. Here's a breakdown of what’s recommended:

Containment helps control overspray, protects the surrounding environment, and makes cleanup easier.

1. Use tarps or plastic sheeting: Enclose the blasting area with heavy-duty plastic sheeting or tarps to prevent soda media from drifting into unwanted areas.

2. Create a controlled work zone: For indoor jobs, use containment walls or negative air machines to keep dust from migrating. For outdoor jobs, barriers or windbreaks (like fencing with sheeting) can help.

3. Consider a blasting booth or tent:
If you're doing frequent or professional work, investing in a dedicated blasting enclosure helps improve safety and cleanup speed.

There are some tips and tricks like dropping 6 mil plastic sheet down in your blasting area. Afterwards, you can cut the sheet into sections, and roll them up for easy disposal. Also, if you don't want to haul away spent media and debris when the job is done, consider using a debris pickup service.
