CO2 laser can also be used on metals and is particularly suitable for cleaning and paint stripping. Laser cleaning is used at an industrial level for the maintenance of machinery, tools and products. It can be useful to remove processing residues such as grease, rubber or other carbon-based materials. Laser paint stripping is part of the laser cleaning application family, where the laser is used to remove a layer of paint from a large or small metal surface. Both laser cleaning and laser paint removal utilise the CO2 laser's ability to selectively target only the materials that are compatible with its wavelength. Cleaning operations can therefore be carried out without the risk of accidentally damaging or abrading the surface to be cleaned.
