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 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 or water.

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

The benefits of soda blasting

Baking soda is considered a soft abrasive. It is typically harder than the surface contaminant, but softer than the substrate. 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. For example, remanufacturing where you don’t want to change tolerances of a part. Also, cleaning machinery on a regular basis, including food processing equipment, without causing extra wear. Soda is also water soluble making sure no abrasive remains in critical areas.

What can I Soda Blast - 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 will leave smooth surfaces and won't leave a rough texture or anchor profile.

Soda Blasting Uses and Applications

  • Paint removal
  • Protective coating removal
  • Cleaning in food processing facilities
  • Stripping and cleaning car frames and parts

Soda Blasting Equipment

Many options exist for soda blasting equipment. The American made Dustless Blasting Equipment line is one of the best options on the market – giving you the versatility to switch between dry blasting, wet blasting, and soda blasting applications.

Dustless Blasting Equipment is best for Soda BlastingLearn more how to get started with blasting by improving your existing business, tackling a specific project, or starting your own mobile Dustless Blasting business.

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"

Dustless Blasting Equipment is an all-in-one system on a mobile trailer or flatbed truck, that you can use for soda blasting, wet blasting, and dry blasting applications.

If you already own an air compressor, they also offer blast pots and Air Drying and Cooling Solutions.

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.

With the popularity of soda blasting and other types of abrasive blasting, be cautious of manufacturers and retailers offering low quality equipment trying to make a quick buck.

Soda Blasting Media – Sodium Bicarbonate aka "Baking Soda"

With regards to abrasive blasting, people often use the common term "sandblasting", but there are several types of other blast media that can be used.

As we've previously mentioned, soda blasting refers to a type of abrasive blasting that uses "soda" or Sodium Bicarbonate.

Soda has some important uses, but it's not perfect. Sodium Bicarbonate can't be recycled or reused like other abrasives that can – silicon carbide, aluminum oxide, garnet, plastic beads, steel shot, steel grit, etc.

One of the most important differences between abrasive blasting with sodium bicarbonate (baking soda) versus abrasive blasting with any other abrasive medias are that baking soda’s attributes allow it to remove contaminants without surface damage to the underlying substrate.

Sodium Bicarbonate on MOHS Scale

Sodium bicarbonate is considered a softer abrasive blasting media. 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 you're 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 and Rust

For best results, after blasting we always recommend a rinse with a rust inhibitor and getting your primer coat on as quickly as possible to prevent flash rusting. Dustless Blasting equipment allows you to mix rust inhibitor in your blast pot or use air tool attachments to quickly lay down a coat of primer after blasting.

Costs of Soda Blasting

Soda blasting can be slightly more expensive than other blast media. When possible it's best to use equipment that allows you to use a wide variety of abrasives and consider a cheaper abrasive like recycled glass.

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. Best practice is to set up containment and prevent the blast media from contacting the plants.

soda blasting and the environment

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, it's recommended to avoid regular baking soda from the grocery store and purchase blast media specifically formulated and manufactured for soda blasting applications.

Safety tips for Abrasive Blasting

Consideration should aways be given to what type of coating is being removed, what type of abrasive is being used, and what environment you're blasting in.

Always practice safety precautions and containment for any blasting operation. This includes Personal Protection Equipment for all workers.

Dustless Blasting machines are capable of both wet (dustless) and dry blasting applications, making it a very versatile tool.

Soda Blasting in Action

While wet blasting is preferred for dust suppression, there are occasions where dry blasting (like soda blasting) is appropriate.

Keep these tips in mind:

  1. Always where the proper protective equipment. We recommend the RPB Nova 3 Blast Respirator.
  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

A soda blaster can be used wet or dry. When used wet, the water acts as a dust suppressant and the dust will typically fall in 10-15ft of the work area. However, when blasting dry, containment for the dust is typically required.

Soda Blasting Containment and Cleanup

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.
