How to Clean Granite Countertops?

Granite is an igneous rock, meaning it was formed from cooled magma. While it is incredibly hard, it is also naturally porous. Most granite countertops in the U.S. are professionally sealed during installation to prevent liquids from seeping into the stone’s microscopic “pores.” To maintain a “Masterpiece” kitchen, you must use cleaning methods that do not strip away this protective sealer. Using the wrong chemicals—even just once—can “etch” the stone, leaving dull spots that require expensive professional restoration.

Quick Answer: Use pH-Neutral Cleaners and Avoid Acidic Products

The most effective way to clean granite is to use a specialized daily granite cleaner or a mixture of warm water and mild, pH-neutral dish soap. You must strictly avoid any acidic or abrasive substances, as these will dissolve the sealant and eventually the stone itself.


Daily Cleaning Routine for Granite

  1. Clear the Surface: Move all appliances and décor to ensure you reach every corner where crumbs and moisture hide.
  2. Dry Dust: Use a dry microfiber cloth to sweep away loose debris. Granite can be scratched by tiny grains of sand or grit if they are dragged across the surface during wet cleaning.
  3. The Soapy Wipe: Use a soft cloth dampened with warm water and a drop of mild dish soap. Wipe in a “S” pattern to capture oils and food residue.
  4. Rinse and Buff: This is the most important step for granite. Wipe again with a cloth dampened only with fresh water to remove soap film. Then, use a clean, dry microfiber cloth to buff the stone in circular motions. This creates the “Masterpiece” high-gloss finish and prevents streaks.

How to Remove Stains from Granite

If a liquid has bypassed the sealer and caused a stain, you can often “pull” it out using a poultice:

  • Oil-Based Stains (Grease, Milk): Create a paste of baking soda and water. Apply a thick layer over the stain, cover with plastic wrap (poke a few holes for air), and let it sit for 24 to 48 hours. As the paste dries, it draws the oil out of the stone.
  • Water-Based Stains (Juice, Coffee): Create a similar paste but use baking soda mixed with a tiny amount of hydrogen peroxide.
  • Organic Stains: For mildew or dark organic spots, a specialized stone-safe mold remover is recommended over bleach.

Sealing Granite: The Protection Phase

Granite is not a “set it and forget it” material. To maintain its integrity, it must be resealed periodically.

  • The Water Test: Pour a tablespoon of water onto various spots on your counter. If the water beads up, your sealer is healthy. If the stone darkens or the water soaks in within 5 minutes, you need to reseal.
  • Frequency: Most high-traffic U.S. kitchens require resealing every 6 to 12 months.
  • Application: Use a high-quality impregnating sealer. Apply to a clean, dry surface, let it sit for the recommended time, and wipe away the excess completely to avoid a hazy film.

FAQ: Granite Countertop Care

Can I use vinegar or Windex on granite?

No. Vinegar is highly acidic and will “etch” the granite. Standard Windex contains ammonia, which strips the sealer and dulls the stone. Always use ammonia-free, pH-neutral cleaners.

Why does my granite feel “gritty” even after cleaning?

This is often caused by mineral buildup or soap scum. Using a specialized granite-safe deep cleaner once a month can remove this invisible layer and restore the smooth, masterpiece texture.

Is granite more durable than quartz?

Granite is more heat-resistant than quartz, but it is more prone to staining because it is porous. Both require specific care to stay in top condition.
