Also, the granite in countertops must be sealed to make it resistant to stains. Here are some steps of how to clean granite countertops.

Seal the Granite Countertop

Granite is a natural stone and each slab used to make the countertop is unique. Although granite is fairly non-porous, several manufacturers seal the slabs before they are shipped. However, despite this, you must reapply the granite sealer occasionally. The sealers applied in the factory can last for several years, depending on the wear and tear of the granite countertop.

You can either ask your manufacturer to check if your countertop needs to be resealed or you can perform the water bead test. Pour a few drops of water on your granite countertop. If the water beads up, this means that the countertop is fine and does not require sealing. If the stone absorbs the water or it leaves a watermark, then the countertops require to be sealed.

There are several types and brands of sealers available on the market and there are also sealers that can be sprayed on the countertop, which are quite easy to apply.

Remove the Water Spots and Stains

To remove dark spots, rings and oil stains from your granite countertop, you can use a thick paste of baking soda and water. Place this paste over the stain and cover it with plastic wrap. Let it sit for 24-48 hours. The baking soda paste can help to absorb the stain from the granite.

If this does not help to remove the stain, then you could try sprinkling some corn starch on the stain directly. Cover this with plastic wrap and let it stay for a few minutes. The corn starch may absorb the remainder of the stain.

You could also use other methods for removing stains such as:

  • A mixture of flour and dish soap
  • A mixture of rubbing alcohol and water (1 part alcohol with 8 parts of water)
  • A mixture of baking soda, water, and some hydrogen peroxide
  • A mixture of baking soda and molding plaster
Microfiber Cloths

Wipe the countertops with the solution of soap and water. Once this is done, dry the counters with a soft cloth completely. Do not allow the water to sit for a long time because it will form a water stain.
