Sandblasting refers to the process of cleaning a surface using compressed air and aggregate. Soda blasting is the gentlest type of this method, but it differs from sandblasting that uses mineral or other aggregate, since sodium bicarbonate breaks apart more easily than other forms of blast media and, therefore, cannot be reused.

Sandblasting removes old paint, rust, and grime efficiently, providing a clean surface for refinishing.

Soda-blasting systems are slightly more expensive than sandblasting systems. To soda blast, you’ll need to spend a few hundred dollars for a blast hose and nozzle, a compressed air supply, a blast generator, a moisture decontamination system, and sodium bicarbonate media, a recurring cost because the powder is not reusable. To start with sandblasting, you will need to spend upwards of $30 for a blast pot, a blast gun, an air compressor, and sandblasting media, many of which are recyclable—further reducing the cost. The total cost for either will depend on the size of the system.

The disadvantages of sandblasting are noise, mess, and risk. Sandblasters are louder than chainsaws and spread debris on the ground and through the air. Let your neighbors know that you're sandblasting so they can prepare. Sandblasting can damage your property if not done properly, so thoroughly vet any pros you talk to before hiring.
