In very basic terms, dry ice blasting involves "blast cleaning" a surface with compressed air, and dry ice particles, usually in the form of dry ice pellets. Fine CO2 (dry ice) particles are "blasted" on to a surface, the unwanted contaminants freeze and fracture, then an explosion of energy takes place, resulting in the thorough removal of the unwanted coatings. This non-destructive method of safely cleaning surfaces and/or removing unwanted coatings has become the preferred method to remove smoke soot, vaporized synthetic resins, and char associated with fire damage restoration. Furthermore, dry ice blasting can eliminate the musty burnt smell that results from fire, smoke, and water damage.
