How to Clean Granite Countertops?

Learn how to clean granite countertops properly without damaging the stone or stripping the sealant.

Granite is one of the most sought-after materials for American kitchens and bathrooms. Its natural beauty, heat resistance, and unique patterns make it a centerpiece of the home. However, because granite is a natural, porous stone, it requires a different level of care than synthetic surfaces like laminate or quartz.

At Lily Maids, we see firsthand how the right maintenance can keep a stone looking brand new for decades, while the wrong cleaners can lead to permanent dulling or etching. This guide will teach you how to protect your investment and keep your granite surfaces sparkling.

Quick Answer: Mild, Non-Acidic Cleaners Work Best

The golden rule for granite is simplicity. You don't need expensive, high-tech chemicals to keep it clean. In fact, most heavy-duty household cleaners will do more harm than good.

Why Granite Needs Gentle Care

Granite is composed of various minerals, some of which are sensitive to acids. More importantly, most granite countertops are treated with a topical sealer to prevent liquids from soaking into the pores. Using harsh chemicals can strip this sealer away, leaving the stone vulnerable to deep, permanent staining and bacterial growth.

Daily Granite Countertop Cleaning

For your day-to-day routine, you only need two basic items that you likely already have in your kitchen.

Warm Water and Dish Soap

The most effective daily cleaner is a mixture of warm water and a few drops of mild, pH-neutral dish soap (like Dawn).

  • The Method: Wet a cloth with the soapy water, wipe the surface to remove crumbs and grease, and then—crucially—dry the surface with a fresh microfiber towel.
  • Pro Tip: Drying the countertop is the secret to a streak-free shine. If you let it air-dry, the minerals in the water or the soap residue can leave a cloudy film.

Soft Cloths and Sponges

Avoid using the "scrubby" side of a sponge or any metallic scouring pads. Even though granite is hard, the sealer on top is not. Use microfiber cloths or soft cotton towels. These are gentle on the stone’s finish and are excellent at picking up small particles without scratching.

Removing Stains From Granite

If a spill has sat too long and left a mark, don't panic. Most stains can be lifted using a "poultice" method.

Oil-Based Stains

Grease, cooking oil, or milk can leave a darkened spot in the stone.

  • The Fix: Create a paste using baking soda and water. Apply it thickly over the stain, cover it with plastic wrap (poke a few small holes), and let it sit for 24 hours. The baking soda will literally "pull" the oil out of the stone's pores. Wipe it away with a damp cloth.

Food and Drink Spills

For organic stains like coffee, tea, or fruit juice:

  • The Fix: You can use a similar paste made of baking soda and a small amount of hydrogen peroxide. Follow the same 24-hour sitting process. If the stain persists, it may mean your sealer has failed and the stone needs professional attention.

What Not to Use on Granite

To prevent "etching" (a chemical reaction that dulls the stone), keep these items far away from your countertops.

Vinegar and Acidic Cleaners

In the cleaning world, vinegar is often a hero, but for granite, it is a villain. The acetic acid in vinegar, lemon juice, and orange-based cleaners will eat away at the sealer and eventually dull the polish of the granite itself. Similarly, avoid glass cleaners like Windex unless they are specifically labeled "SCA" (Safe for Stone).

Abrasive Tools

Never use steel wool, scouring powders, or "magic eraser" style sponges on granite. These contain micro-abrasives that act like fine-grit sandpaper. Over time, they will wear down the glossy finish, leaving a matte, hazy spot that can only be fixed by professional re-polishing.

FAQs

Does granite need sealing?

Yes. Most granite should be sealed upon installation and then resealed every 12 to 18 months. To check if you need a new coat, perform the "Water Drop Test": Place a few drops of water on the counter. If it beads up, you’re safe. If it soaks in and darkens the stone within a few minutes, it’s time to reseal.

Can granite discolor?

Granite can darken if it absorbs water or oil, but this is usually temporary. However, prolonged exposure to direct sunlight can slightly fade certain darker varieties of granite over many years, though this is rare for indoor installations.

How often should granite be cleaned?

You should wipe down your counters daily to remove food particles. A deep clean with a stone-specific cleaner can be done weekly to add a light layer of protection and enhance the natural shine.
