This article presents a parameter optimisation study for the use of an Er:YAG laser in combination with different solvent mixes for the cleaning of a large oil painting on canvas by Jacopo Tintoretto. The painting underwent restoration work between the 1700s and the mid-1900s in which it was lined and some areas were coated with a pigmented protective varnish, which has oxidised over time and has completely obscured the work. Analysis was undertaken in order to study the condition of the work, the painting technique used, and to monitor and verify the effectiveness of the cleaning treatments considered to remove the oxidised varnish. The article reports how the careful calibration and use of cleaning techniques involving the Er:YAG laser and solvent mixes have led to a full recovery of the vibrant chromatic intensity to the pictorial surface of the work.
