Preservation of cultural property for the future is one of the most important activities of our society. The information which we can gather from such materials is a valuable key to understanding the past. Conservation is a process which includes a range of different treatments. Cleaning is one of the critical steps of the conservation process and involves stabilizing the material and the exposure of hidden details on the surface of the artifact in question. As the artifacts are often fragile and irreplaceable it is very important to choose suitable techniques and methods to avoid damage. Research is still continuing to develop new or improved techniques. One of these new techniques is laser cleaning which has shown good potential as a cleaning tool in many material categories in conservation work.
