Watch a video showing conservators using laser cleaning on several items.

This video clip demonstrates the effectiveness and versatility of laser cleaning. It shows conservators working on materials including a detailed and fragile stonework frieze and the outside of an old building. The flexibility of the technique is really shown when a live rose is successfully cleaned.

The conservators are shown holding a pen-like structure which is used to accurately direct the short pulses of infrared light on to the area being cleaned. You can see the light flashing on the surface of the object. Once the pulse has faded you can see the underlying material is much cleaner, while the surrounding area is left unaffected.
