Advantages of dry ice cleaning technology over other cleaning technologies

Replace sandblasting This method is better than sandblasting because dry ice is soft enough not to damage the surface below. Dry ice quickly sublimates into the air, and only cleans up the substances that need to be removed. Dry ice cleaning eliminates equipment damage in two ways. First of all, dry ice will not erode or wear equipment surfaces like traditional grit media or even wire brushes. ...
