Dry ice cleaning, also known as dry ice blasting or CO2 blasting, is a cleaning process that uses solid carbon dioxide (CO2) pellets or particles accelerated at high speeds to clean surfaces. The process involves using compressed air to blast dry ice pellets onto the surface to be cleaned, which then sublimate, or turn directly from a solid to a gas, upon impact with the surface. The sublimation process creates a powerful kinetic energy that removes dirt, grime, and other contaminants from the surface being cleaned. Dry ice cleaning is a non-abrasive, non-toxic, and environmentally-friendly cleaning method that does not require the use of water or harsh chemicals, making it a popular option for industrial cleaning applications. It can be used for a variety of cleaning tasks, including removing paint, mold, grease, and oil from machinery, equipment, and buildings.
