Laser cleaning is the process by which contaminants, debris or impurities (e.g. carbon, silicon and rubber) are removed from the surface of a material by using laser irradiation. This is a low-cost and environmentally-friendly laser application technique, which is in widespread use throughout global industry.
There are two types of laser cleaning process, which are typically used:
- One which is the removal of a layer on the surface of a material,
- While the second is the removal of the entire upper layer of a material.
Laser Cleaning technology is a remarkable and unique tool for architectural restoration and conservation. Cleaning with laser light has proven to be the most gentle and effective method for restoring the beauty of historic architectural treasures including sculptures, bronze statues, ornate terracotta as well as entire building facades.
Laser cleaning removes harmful and unsightly deposits without chemicals, abrasives, water, dust or residues that can permanently damage historic surfaces. Moreover, laser cleaning is a green process; it produces no secondary waste, no run-off and no dust that can pose risks to people and the planet. Laser cleaning offers conservators an amazing tool to clean and enhance historic surfaces in a way not possible with any other method.

Historic metal conservation
Laser cleaning works by using extremely short duration pulses of laser light, scanned across the surface to vaporize soil, carbon deposits, oxides with other organic and inorganic contaminants. A fume extractor is used to capture the vaporized residues as they are removed for a dust free process with nothing to clean-up. The equipment is designed for safe use in a wide-range of applications. For personnel safety, the operator, and nearby observers, wear special laser safety glass that provides comfortable eye protection, in addition to other simple to implement procedures.
In the hands of a skilled restorer or conservator, this simple to use handheld laser cleaning tool can produce amazing results as it uncovers and helps preserve the natural beauty of our cultural treasures.
