Polishing up is a process of making something look better and more attractive. Burnishing is the act of rubbing a hard, smooth surface with a tool to make it shinier. Waxing is the application of a WAX-based product to a surface to protect it and give it a glossy finish. Finally, shining is the act of buffing a surface with a cloth to make it look brighter and more reflective. Together, these three processes can be used to polish up an object and make it look its best.
