Laser parameters should be carefully selected to achieve the removal of the target contaminants without inducing damage to the substrate. Ultra-short pulse lasers have opened new opportunities for safe and controlled decontamination of cultural heritage materials because the thickness of material that is affected by the laser is limited. In this study, an ultraviolet femtosecond pulsed laser was used for the removal of unwanted encrustation formed on the surface of an historical colourless stained-glass sample from the Cuenca Cathedral in Spain. One of the sides of this glass exhibits a reddish-brown grisaille that also has to be preserved. A laser cleaning process has been designed to avoid heat accumulation while controlling the thickness of ablated material. In this context, a multi-step process was selected in order to be able to eliminate, in a controlled way, the crust layer without damaging the grisaille layer, or the glass substrate. In this case, laser irradiation in beam scanning mode with a pulse repetition frequency of 10 kHz proved to be effective for the safe cleaning of the glass. The latter was analysed before and after laser cleaning by optical and confocal microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray fluorescence, and Raman spectroscopy, confirming that the crust layer was effectively eliminated without damaging the surface. 000126020 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T54-20R$$9info:eu-repo/grantAgreement/EC/H2020/766311/EU/European Doctorate in ARchaeological and Cultural Heritage MATerials science/ED-ARCHMAT$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 766311-ED-ARCHMAT 000126020 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000126020 590__ $$a3.5$$b2023 000126020 592__ $$a0.722$$b2023 000126020 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b58 / 253 = 0.229$$c2023$$dQ1$$eT1 000126020 593__ $$aAnthropology$$c2023$$dQ1 000126020 591__ $$aSPECTROSCOPY$$b6 / 44 = 0.136$$c2023$$dQ1$$eT1 000126020 593__ $$aArcheology (arts and humanities)$$c2023$$dQ1 000126020 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b185 / 438 = 0.422$$c2023$$dQ2$$eT2 000126020 593__ $$aConservation$$c2023$$dQ1 000126020 591__ $$aCHEMISTRY, ANALYTICAL$$b32 / 106 = 0.302$$c2023$$dQ2$$eT1 000126020 593__ $$aHistory$$c2023$$dQ1 000126020 593__ $$aEconomics, Econometrics and Finance (miscellaneous)$$c2023$$dQ1 000126020 593__ $$aMaterials Science (miscellaneous)$$c2023$$dQ2 000126020 593__ $$aSpectroscopy$$c2023$$dQ2 000126020 593__ $$aComputer Science Applications$$c2023$$dQ2 000126020 593__ $$aChemistry (miscellaneous)$$c2023$$dQ2 000126020 594__ $$a6.8$$b2023 000126020 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000126020 700__ $$aAlonso, M.
