Soda Blasting FAQs

In the past, unsightly surface contaminates such as paint, dirt and grease could only be cleaned by either chipping off manually or using harsh chemicals. Recently, a new technology known as soda blasting has emerged.
With any new technology comes many questions. How does it work? Is it safe? Is it expensive?

History

Engineers for the state of New York were researching ways to clean the Statue of Liberty. Their concerns were about the environment, disposing of waste and protecting the landmark's surface.

Soft copper plates make up the exterior of the Statue of Liberty. This meant abrasive methods such as sand blasting were not an option. The process of soda blasting was recognized. It addressed all the concerns of the engineers, and it worked so well that it is now being used commercially and at home as a safe and effective method of cleaning surfaces.

Function

Soda blasting is a cleaning process where sodium bicarbonate is applied to a contaminated surface using compressed air. There are many uses for soda blasting, including:

* Cleaning
* Paint stripping
* Automotive restoration
* Industrial equipment maintenance
* Rust removal
* Graffiti removal
* Masonry cleaning
* Boat hull cleaning

A soda blaster is a machine that contains a blast generator, high-pressure compressed air, blast hose and nozzle and a moisture decontamination system.

Benefits

The blasting material used in soda blasters is sodium bicarbonate, also known as baking soda.
Soda blasting is FDA approved and non-toxic; it is non-flammable, non-hazardous and environmentally safe. It also is less harmful to the surface being cleaned than most chemicals used in the past.
Sodium bicarbonate is a rust inhibitor; it leaves a protective coating on the surface being blasted.
In most municipalities, sodium bicarbonate can be disposed of using conventional drainage systems. This saves money on not having to use expensive waste disposal services.

Cost

Soda blasters are extremely effective in safely removing contaminates from many surfaces. However, this convenience comes at a price.
You can purchase a starter soda blaster -- which is good for most household uses -- starting around $300. For this price, you get a blasting machine, 50 pounds of sodium bicarbonate, 100-pound capacity hopper and 8-foot blast hose.
If you require a machine built more for industrial use, be prepared to spend a minimum of $3,000. For the extra money, you get more pressure, a larger hopper, longer hoses and a higher-quality system.

Warning

As with any high-pressure system, caution should be taken while operating soda blasting equipment. Proper eye wear should be used at all times. Always consult a professional if you are unsure of how to use the equipment.
