Dry ice blasting, also called dry ice cleaning, is an environmentally responsible cleaning and surface preparation technique. Dry ice blasting uses solid carbon dioxide (CO2) pellets or MicroParticles, which are blasted at supersonic speeds and sublimate on impact, lifting dirt and contaminants off the underlying substrate. Dry ice cleaning is non-abrasive, non-conductive, non-toxic, and non-flammable. It is similar to sand, bead and soda blasting in that it prepares and cleans surfaces using a media accelerated in a pressurized air stream. It differs in that dry ice cleaning uses solid carbon dioxide (CO2) pellets or MicroParticles, which are blasted at supersonic speeds and sublimate on impact, lifting dirt and contaminants off the underlying substrate.
