Corn Cob cleans and polishes without damaging the surface. It is used as an alternative to other organic abrasives containing oils that may stain the substrate or affect coating adhesion. A very soft abrasive used exclusively for burnishing, polishing, deburring, and drying metal and plastic parts. Due to its tough, resilient, dust free character, it is excellent for soft grit blasting and tumbling. Log cabins and historic buildings, electrical insulators and transformer substations, wood and fiberglass boat hulls and aluminum pontoons, metal finishings and fixtures, grease and grime removal from construction and off-road equipment are just some of the uses.
