Dry ice blasting works on three levels almost instantaneously to get you the cleanest end product possible. The pictures below show each step of the dry ice blasting process; kinetic, thermal, and sublimation. Here’s how it works:

First, dry ice blasting uses the kinetic energy created by the combination of compressed air and blasting dry ice pellets to penetrate the first layer of grime, such as dirt, grease, paint, and/or many other things that could coat the object being cleaned.

The second step in the process is the thermal effect. The temperature of the dry ice (-109° F) causes the much warmer temperature of the dirt and grime to drop rapidly and separate from what is being cleaned. The thermal effect causes the layer of grime to separate from the surface.

Upon impact, the solid blasting dry ice pellets turn to a gas, which is the third and final step called sublimation. The volume expansion of the blasting dry ice causes a micro-explosion that removes the undesired layer leaving it contaminant free.

All three levels work together to create the dry ice blasting process.
