Dry-ice Blasting

Dry-ice blasting is a form of abrasive blasting where dry ice is accelerated in a pressurized air stream and directed at a surface in order to clean it. Why use dry-ice? Dry-ice leaves no chemical residue as it sublimates at room temperature. Essentially, the sublimation process absorbs a large portion of heat from the surface which produces shear stress due to thermal shock. This is claimed to improve cleaning as the top layer of dirt is expected to transfer heat and flake off very easily.



Dry ice cleaning removes the following:

Paint/varnish
Oil
Grease
Tar
Bitumen
Dirt
Ink
Resin
Adhesives
Wax
Binders and solvents
Silicon/rubber residues
Chewing gum
Graffiti
…And much more
