Cryogenic cleaning is a technique that uses dry ice and its physical properties to instantly remove dirt, grease, or contaminants from any surface.
It is performed by projecting dry ice directly onto the surface to be cleaned.
Dry ice is produced as small pellets 3mm (0.12 in) that are crushed into a powder by a device called a "blaster", which is coupled with a compressed air compressor for high-speed projection.
The very low temperature of dry ice combined with its high projection speed allows it, upon contact with dirt at ambient temperature, to instantly transform into gas by creating a microscopic mini explosion, thereby dislodging all dirt including grease. This process is called sublimation.

This technical solution constitutes a highly efficient, cost-effective, and eco-friendly alternative delivering an exceptional result compared to traditional solutions.
The cleaned surfaces are perfectly degreased without the slightest use of solvents or degreasers.
When dry ice sublimates upon contact with the substrate, it produces no secondary waste, as seen in sandblasting, for example.
CO₂ is inert, non-flammable, and non-toxic.
By not using water, all risks associated with corrosion or bacterial growth are eliminated.
Cryogenic cleaning produces no abrasive effect. The particles have a hardness of approximately 2 Mohs (comparable to that of chalk) so that the treated surfaces are not damaged.
