If the pad begins to dust or stick during polishing, it is time to clean and remove the accumulated dirt and used polish from it. The easiest way to do this is by using the cleaning brush. Simply press the brush against the rotating pad at low speed and allow the bristles to brush the dirt out. After polishing, all pads can be washed out with water and a little cleaning agent. Note that lambskin pads should be left wet and re-attached with the Velcro face onto the polishing plate in order to prevent them from shrinking and losing their shape.
