Dry-ice blasting is a form of carbon dioxide cleaning, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it.
The method is similar to other forms of media blasting such as sand blasting, plastic bead blasting, or sodablasting in that it cleans surfaces using a media accelerated in a pressurized air stream, but dry-ice blasting uses dry ice as the blasting medium. Dry-ice blasting is nonabrasive, non-conductive, nonflammable, and non-toxic.
Dry-ice blasting is an efficient cleaning method. Dry ice is made of reclaimed carbon dioxide that is produced from other industrial processes, and is an approved media by the EPA, FDA and USDA. It also reduces or eliminates employee exposure to the use of chemical cleaning agents.
Compared to other media blasting methods, dry-ice blasting does not create secondary waste or chemical residues as dry ice sublimates, or converts back to a gaseous state, when it hits the surface that is being cleaned. Dry-ice blasting does not require clean-up of a blasting medium. The waste products, which includes just the dislodged media, can be swept up, vacuumed or washed away depending on the containment.
