Dry ice blasting

Dry ice blasting is the use of the solid form of carbon dioxide ("dry ice") as an abrasive blasting medium.
Because of the prohibitive cost of dry ice blasting, it's simply not currently economically justifiable for stripping paint from body panels. In addition, dry ice may not be abrasive enough to remove all paint coatings. Because it's cold, dry ice may also introduce condensation in humid conditions, especially on metal.
The main advantage of dry ice is that it doesn't leave any residue, because dry ice sublimates at room temperature. It's a relatively mild blasting media, used for cleaning electric motors and other delicate parts where the introduction of blasting media could be disadvantageous. Dry ice does not leave an anchor pattern.
Dry ice blasting is the process of shooting very small pellets of dry ice at a substrate. When the dry ice hits the substrate, they immediately sublimate causing the debris to be blasted off.
