PUMICE STONE AND ROTTEN STONE are polishing materials. Rottenstone is one of the finest abrasives used in the refinishing of wood. It is used primarily in powder form to polish a varnished or lacquered surface after coarse rubbing with pumice.
To Use: Dip dampened felt block in powder and rub. Begin with various pumice grades and final polish with rotten stone to obtain desired luster. Be sure to remove all powder grit before final wax coat, if used. The use of rubbing oil to dampen cloth will produce a more dull-satin finish than if water is used.
