Conservation and restoration of artworks and objects of historical interest is a science that combines several areas of knowledge. The surface cleaning step is an essential and critical process in every conservation procedure, because it involves traditionally invasive processes that are hard to control. The laser cleaning method is a viable solution, and in widespread interventions in marble and metal. Studies demonstrate the viability of the use Nd YAG laser for cleaning paper. The support to be treated is a paper of mechanical pulp, from the 30s, by 532nm laser beam. The evaluated parameters were the operational mode, the exposure time, the energy deposited and the focal length parameters. Classical wet method was used for comparison, aqueous cleaning was performed to establish the efficiency of traditional methods and laser. The paper surface was characterized by visual inspection, CIELab method and scanning electron microscopy SEM. Some conditions did clean the surface with minor damage.
