CO2 Process
Dry ice blast cleaning is a process in which particles of solid carbon dioxide, commonly known as dry ice, are propelled at high velocity to impact and clean a surface. Upon impact, the CO2 particles return to their natural state as carbon dioxide gas, thus disappearing as they clean. Although it is often compared to sand blasting, bead blasting, or soda blasting, dry ice actually clean differently. Traditional abrasive blasting methods clean through a chiseling action, much like using an ice pick, but often take away part of the substrate as well. Dry ice, on the other hand, might better be compared to a spatula as it lifts away the contaminant without damaging the targeted surface.
