A closer look

Sandblasting leaves an abrasive mess everywhere, so clever engineers started shooting frozen carbon dioxide instead. Dry ice blasting fires sub-zero pellets at heavily soiled machinery. Upon impact, the extreme cold forces the grime to abruptly shrink and crack away from the surface. Instantly after impact, the solid pellet sublimates, violently expanding into a gas and blowing the dirt away, leaving behind absolutely zero blasting residue.
