Blasting with dry ice pellets removes old coatings, rust and dirt without damaging the substrate below, but unlike other blast media, on impact the pellets are converted into a gas and released into the atmosphere, making the process dust and contaminant free, The technique is particularly suitable for cleaning detailed or delicate components and in markets such as food processing, electronics or pharmaceuticals where contamination or surface damage cannot be tolerated.
