Things You'll Need
Liquid dish detergent
Granite sinks are a popular choice. With their sophisticated look, they can add significant value to a kitchen or bathroom. The stone is very durable, but also quite porous, making it easy to accumulate stains. Clean up spills as soon as possible to prevent stains from setting into the granite. If a spill creates a surface stain, remove it using a mild household cleaner.
Blot the stained area of your sink with a paper towel to remove any excess residue.
Mix some mild liquid dish detergent with warm water to form a soapy solution. Dip a clean cloth into the solution and wipe the area thoroughly. Rinse the area with water. The detergent will work to remove many oil-based stains such as cooking oil and grease.
Dry the affected area of the sink with a clean cloth.
Mix a small amount of hydrogen peroxide and a few drops of household ammonia to remove stains of food, coffee and tea. Apply the solution to a clean cloth and blot the stained area. Rinse the area with water, then wipe dry.
Create a paste of baking soda and hydrogen peroxide for persistent stains. Cover the stain with the paste and place a damp cloth on top of the paste. Leave the treatment overnight. Dampen a cloth with water and wipe away the paste. Rinse the area with water and wipe dry.
