Dry ice blasting, or dry ice cleaning, is an environmentally responsible cleaning and surface preparation technique.
It is similar to sand, bead and soda blasting in that it prepares and cleans surfaces using a media accelerated in a pressurised 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.
The process is non-abrasive, non-conductive, non-flammable, and non-toxic. The dry ice blasting process also does not create secondary waste. The dry ice sublimates, or phase transitions from solid CO2Â to gaseous CO2, when it impacts the surface being cleaned.
