Abstract
The laser cleaning of historical sandstone was investigated using air and also pure N2 for shielding of the laser interaction region. The yellowing measured in the colorimetric L*a*b* space was lower by more than 20% for samples cleaned in nitrogen. The effect was ascribed to the dirt combustion products on the surface due to ablation plume and confirmed by the surface inspection.
