You can do your own granite repair on a stained countertop to restore it back to its original condition and prevent further damage. Clean spills of acidic substances such as juices, wine, and cooking oil as soon as possible to prevent staining. If left to sit, however, even water can stain granite. Follow the steps below to inexpensively and effectively remove water stains from your countertop.
Step 1 – Assess the Damage
Check the affected surface and determine whether you will be able to remove the stain.
Step 2 - Clean the Stained Surface
Clean the stained surface with stone soap or mild dishwashing liquid and warm water. Clean the granite using a soft clean cloth and then leave it for a few hours. Wear gloves while you work.
Step 3 – Remove Water Stains
Spray distilled white vinegar on the stained area. Cut a lemon in half, and then scrub it directly on the stain. Prepare a paste of white vinegar and baking soda. Let the paste sit on the stain for a short time (not too long, since this mixture can damage the sealant) then rinse with water.
Rub granite cleaner directly into the water stain. Allow the solution to sit for a couple of minutes, and then rinse thoroughly with water.
Step 5 – Repeat If Necessary
Polish the granite with a soft cloth. Repeat steps 2, 3, and 4 until water spots are removed. If the stain remains, you may need to repeat the process again until the stain is totally removed.
Step 6 – Seal the Countertop
Once the water stains are gone, you must seal the granite countertops to help maintain and ensure the durability of the surface. It keeps countertops shiny and even helps resist stains. In areas where you will prepare food, you should use a non-toxic sealer. This will also keep the polished surface looking shiny.
Step 7 - Maintenance
You can use a sponge and hot water to clean up spills and also use a granite cleaner when necessary.
