So much more than microfibre.

To achieve the ultimate clean, we need to go microscopic. Calocloth is made up of tiny split fibres, which collect even the finest particles.

Unlike traditional cloths, the wedge-shaped yarn that makes up Calocloth traps even the finest dust and residue, leaving behind a truly clean, scratch-free surface.
