Burnishing Pads for  SUNMAX RT120 Floor Scrubber Machine  and SANITMAX SM860 Ride-on Floor Scrubber Machine (Pack of 5) Diameter: 16” White Pads: These are the least abrasive pads, ideal for polishing clean, dry floors. White pads are perfect for buffing soft finishes on wood or for polishing natural stone floors to a high shine without causing damage. Red Pads: A bit more abrasive than white, red pads are designed for light cleaning and spray buffing. They can be used on most floor types to remove light scuffs and black marks and to enhance floor appearance. Black Pads: These are the most abrasive pads, primarily used for stripping off old finishes and wax from hard floors, such as concrete or stone, before applying a new coat. Not recommended for delicate floors, as they can scratch and damage the surface.
