Dry ice is created from fluid carbon dioxide by means of rapid decompression.

Kärcher dry ice blasters work with dry ice pellets with a diameter of 3 mm.

Dry ice sublimates completely, i.e. it has no liquid aggregate state but rather becomes a gas as soon as it strikes the surface being cleaned.

Dry ice pellets are available almost everywhere in industrialized countries.

The -78°C carbon dioxide snow is compressed into 3 mm-sized pellets.
