This invention is directed to a method for improving the quality of pumice stones that are used to finish fabrics or garments with a distressed look. In this invention, the pumice stones are first injected with steam at a pressure above atmospheric pressure to remove dust and other particles, and to drive the air out of the pumice stone pores. The steam cleaned stones are impregnated with an oxidizing agent. The high pressure steam pretreatment enables the pumice stones to absorb the oxidizing agent solutions quickly and throughout the entire stone, resulting in an even and thorough penetration of the oxidizing agent solution in the pumice stones, which can then be used to distress fabrics and garments.
