Abstract
Effective cleaning of an article can be achieved by a method comprising scrubbing the surface of the article by means of a cleaning roll having a surface layer of polyvinyl acetal porous elastic material having a porosity of 85% to 95%, an average pore opening of 10 to 200 .mu.m, and a 30% compression stress in the state characterized by a water content of 100% based, on the dry weight of the material, of 15 to 150 g/cm.sup.2.
Claims6
A method for thorough cleaning of a finely finished surface of an article of glass or metal by removing cuttings, shavings, turnings, abrasive grains and fine particles from said surface, comprising scrubbing said surface by means of a cleaning roll having a surface layer of polyvinyl acetal porous elastic material having a porosity of 85% to 95%, an average pore opening of 10 to 200 .mu.m, and a 30% compression stress, at a water content of 100% based on the dry weight of the material, of 15 to 150 g/cm.sup.2, whereby said surface is thoroughly cleaned of even fine particles without causing damage to the fine finish of said surface.
