When it comes to the proper care and maintenance of granite countertops, there is a lot of misinformation floating around. Follow these simple steps to keep countertops shiny and bright.

Step 1: Well-sealed countertops are less permeable to liquids and therefore less likely to be stained. Test the porosity of the stone by leaving a large drop of water on the counter top for 10-15 minutes. Wipe away the water with a soft cloth. If the stone beneath the water has darkened, it is time to seal the countertop.

Keep your granite countertop shiny and bright.

Step 2: Choose a penetrating sealant made specifically for granite. Sealers that contain fluorocarbon aliphatic resin work best. Follow the sealant directions. Test the product in a small area before coating the entire countertop. Apply sealant liberally and allow it to penetrate thoroughly. Wipe excess away with a soft cloth.

Step 3: Daily cleaning of granite is best done with a microfiber cloth and clear water. A mixture of equal parts water and rubbing alcohol or equal parts water and hydrogen peroxide works even better at removing the residue of daily life from kitchen and bathroom countertops. Avoid using ammonia- or acid-based cleaners and stay away from abrasive scouring products.

Step 4: Stains from water or oil are typically not stains at all. Given time, these liquids will evaporate, allowing the stone to return to its natural color. Use coasters and hot pads on granite countertops to avoid unnecessary discoloration.

Step 5: A simple poultice is the best way to remove actual stains from granite. For most stains, a poultice made from hydrogen peroxide and diatomaceous earth or whiting works best. Begin by mixing the powder and the liquid together to form a thick paste.

Step 6: Place a dollop of poultice on the stain. The poultice should be at least a quarter-inch thick and should not extend beyond the stain any more than a half inch.

Step 7: Cover the poultice with plastic wrap. Tape the edges of the wrap to the countertop to seal the stained area completely. Allow the poultice to dry for 24 to 48 hours.

Step 8: As the poultice dries the stain should be pulled up and out of the granite. Use a soft cloth or paper towel to wipe away the dried poultice.
