Polishing powders and other agents are commonly used to polish granite surfaces. These agents are typically mixed with water to form a paste that is then worked into the surface with a felt or burlap rag. Special tools such as grinders and stone polishers utilize various grit diamond pads to refinish and polish granite surfaces. Acetone is also used as a solvent to remove thick or greasy stains.
Granite surfaces are very durable but may suffer damage should acidic substances etch their surface. Grease and soap residue may also built up over time leaving the surface looking dull and faded. Abrasive cleansers are effective for polishing granite surfaces, although resurfacing and resealing granite is often the only option to address more extensive damage.
Applying a polishing powder is an effective way to remove most light surface etching, shallow scratches, stains and other residue. Polishes may be specifically formulated to work with either light or dark granite, and not every polish may be suitable for use on all granite surfaces. An etched sealer coat may require resealing. Apply sealer to the surface with either a rag or spray bottle before working it across the granite evenly and allowing it to dry. Application of multiple coats of sealer can provide superior protection for granite surfaces.
