How does dry ice cleaning work?
Dry ice cleaning uses frozen CO2 to clean objects. This method of industrial cleaning fires ice pellets (CO2 in solid form) at the surface to be cleaned. Upon impact, a mini-explosion of sorts occurs, after which the ice pellets evaporate and the layer of dirt begins to release. This is further aided by the temperature shock created: This is because the CO2 is stored at a temperature of -79C.
Dry ice cleaning is a good alternative to laser cleaning in atrex environments. This is because the oxygen levels here poses a risk: A small spark can already pose an explosion hazard. Dry ice removes this risk.
The method is also very suitable for soot and fire damage. It is also possible to clean (active) fuse and switch boxes with dry ice, or to remove graffiti and chewing gum on the street. Since the dirt is not immediately extracted, this application is less suitable for the pharmaceutical or food industry, for example, where hygiene and a clean working environment are of greater importance.
