Investigation of The Effects of The Cleaning Procedures Applied to Stone Surfaces

In the present study several cleaning procedures were taken into account: microblasting, ammonium carbonate, EDTA, etc. The various cleaning procedures were applied to Venetian Istria stone manufacture. The performance evaluation of the various procedures employed was accomplished by measuring the following significant parameters, before and after treatment: colour change through the CIELab method, surface morphology through a fiber optical microscope (MFO) and analysis of the different chemical action of the employed procedures.
