Cleaning with LCO2 uses liquid carbon dioxide instead of water and does not get the gloves wet. When pressurised, the odourless gas liquefies and soaks up any dirt particles like a sponge. After a while, the carbon dioxide is released. Now in gaseous form again, it is stored in a tank and reused in the next wash. During the conversion from a liquid to gaseous state, all dirt particles fall off. The process is similar to shaking out a dust cloth.
