Natural stones, like marble and granite, are porous, meaning that moisture that sits on the surface can seep in and cause stains. Kitchens are full of liquids prone to stain a natural stone, such as fruit juices, wine, coffee, tea, water, vinegar, vegetable and olive oils, ketchup, bbq sauce, etc. Sealing your stone can help prevent this, but it wears down over time.
If you notice water starts to darken your stone, that is the first sign that you need to reseal. But how do you keep your granite countertop in the best shape until you can reseal?
Clean the Area
For an oil-based stain, clean your countertop with a mild grease-lifting dishwashing soap (such as Dawn) and warm water. For other types of stains (coffee, tea, wine, etc.), use a hydrogen peroxide-based cleaning spray. Though gentler “safe-for-stone” options are best for regular cleaning, these work best on dark marks, so use a tougher approach as needed.

Treat Stains
Mix a poultice of baking soda and water (for oil-based stains) or baking soda and peroxide (for others) until you get a consistency like sour cream. Spread the mixture over the spot, cover it with plastic wrap, and secure the edges with masking tape. Let it stand for 24-48 hours.
Remove and Clean
Pull off the plastic and clear the white residue with a wooden or plastic scraper. Rinse the surface with water and wipe with a clean, lint-free cloth.
If your stone still shows signs of a stain, you may need to repeat the process in order to remove it completely or contact a professional to assist you further.
