Polishing is the process of smoothing and shining a surface to improve its appearance. It is commonly used on metals, wood, and other materials to remove imperfections, scratches, and dullness. Polishing can be done by hand using abrasive materials such as sandpaper or polishing compounds, or with the use of power tools such as polishers and buffers. The end result of polishing is a smooth, glossy finish that enhances the overall look of the object being polished.
