For applications not suited to conventional blasting media, we offer several specialty options which include dry ice, sponge media, and soda blasting as well as high efficiency Greener Blast systems. All of these options are environmentally friendly and each offers unique advantages for certain applications.

Dry ice blasting uses pelletized or shaved dry ice to clean the desired substrate. Because dry ice sublimates (i.e. goes from a solid directly to a gas) on contact, minimal clean-up is required, making dry ice blasting ideal for dust-sensitive areas. Dry ice blasting is also EPA, FDA, and USDA approved making it an effective solution for food and beverage processing as well as many production (clean-in-place) applications such use with injection molding machines and printing presses.

Sponge media blasting is a very versatile method that is ideal for applications in which rebounding media or excess dust are principal concerns. As its name suggests, in sponge media blasting a foam sponge type media is used to clean the substrate. A variety of common abrasive media can be incorporated into the sponge to increase the efficacy of the blasting operation, or the sponge material can be used by itself for gentler applications. Additionally, sponge blasting may be performed using media that has been dampened with water or cleaning agents to more effectively remove contaminants and control dust.

Soda blasting (i.e. sodium bicarbonate), commonly referred to as baking soda, is used to gently but effectively remove everything from dirt and oil to graffiti. As an environmentally friendly blasting method, soda blasting can be used in a wide array of applications including historical restoration, fire/smoke damage, and general industrial cleaning.

The Greener Blast system is a high efficiency abrasive blasting system that uses 80 to 90 percent less media than traditional systems. The system is able to use less media during the blasting process because the media is delivered in a high powered slurry which minimizes media waste. The Greener Blast system is available in a packaged unit ready for transport to the jobsite, making it ideal for portable applications in which the media must be tightly contained. Most types of media can be used in the Greener Blast system, making it ideal for a range of applications from gentle to aggressive blasting. Our application specialists can assist you in determining the method that best optimizes cost, performance, and convenience.
