Dry ice (carbon dioxide) pellets are propelled at high velocity using compressed air, creating a powerful yet controlled cleaning action. Upon impact, the pellets rapidly sublimate and expand, producing a micro-thermal shock effect that breaks the bond between contaminants and the underlying surface. This allows grease, oils, dirt, coatings, and other residues to be lifted away without abrasion or damage.

Unlike traditional cleaning methods, this process generates no secondary waste such as water runoff, blasting media, or chemical residue. The pellets instantly convert into CO₂ gas and dissipate safely into the atmosphere, leaving only the removed contamination to be collected. This makes dry ice cleaning a highly efficient, environmentally responsible solution for maintaining equipment and surfaces.
