Sand Blasting vs Soda Blasting – What’s the Difference

Sand Blasting vs Soda Blasting

Blasting is the process of cleaning surfaces, removing old paint or debris, and preparing surfaces for a new coating. Sandblasting and soda blasting are the commonly used methods for blasting. Even though they both serve the same purpose, there are significant differences between the two processes. While they both get the job done, they do it differently. So, it’s essential to know what those differences are and which method is best for your project.

What is Sand Blasting?

Sandblasting is a very common blasting that has been around for many years. It involves firing sand under high pressure at the surface that needs cleaning. This abrasive method removes rust, old paint, and other unwanted materials from metal and other surfaces.

What is Soda Blasting?

soda blasting is a slightly newer method that uses specially formulated baking soda instead of sand for cleaning. This method is commonly used for cleaning delicate objects, like machinery, automobiles, and other sensitive surfaces.

Difference Between Sand Blasting and Soda Blasting

One of the most critical differences between sandblasting and soda blasting is the abrasive material used. Sandblasting is more aggressive than soda blasting, making it the perfect method for removing layers of complex substances like concrete and steel. However, it can destroy surfaces like glass, plastic, and wood. Meanwhile, soda blasting is much less abrasive, making it an excellent choice for cleaning delicate surfaces. Baking soda is much softer than sand, so it does not cause damage to most surfaces.

Another difference is the cleanup requirement. Sandblasting generates enormous dust and particulate matter, making it hard to clean up. This makes sandblasting a potentially dangerous procedure, as the dust can cause respiratory problems if inhaled and can harm nearby animals. On the other hand, soda blasting does not create dust or hazardous materials, making it eco-friendly and easy to clean up. The residue from soda blasting is water-soluble and can easily be wiped away with a bit of water.

When deciding between sandblasting and soda blasting, it’s essential to consider the cost. Sandblasting is typically less expensive than soda blasting. However, sandblasting can be more harmful than soda blasting, increasing costs by requiring more costly cleanups or repairs. Additionally, soda blasting is a newer method, so it may only be widely available in some areas.


Sandblasting is typically more expensive than soda blasting because it requires special equipment and training.


Sandblasting typically takes longer than soda blasting because of the abrasiveness of the sand.


Both sandblasting and soda blasting effectively remove paint or rust from a metal surface.


There’s no clear “winner” in the sandblasting vs soda-blasting battle. Both have strengths and weaknesses and can be highly effective in certain situations. Consider the specific project and surface you’re working on, costs, cleanup requirements, and environmental impacts when deciding which method to use. Remember, to get the best results, it’s essential to use a reliable blasting service with the experience and equipment to get the job done right.
