Black granite countertops are a sleek and luxurious addition to any modern kitchen or bathroom. They are known for their rich tone, glossy finish, and ability to hide stains better than lighter granite. But this doesn’t mean they don’t need care. Regular granite countertop cleaning is essential to preserve their shine and durability.
In this article, you’ll learn the safest and most effective ways to clean, polish, and maintain your black granite surfaces—while also avoiding common mistakes that can dull or damage the stone.
Why Black Granite Countertops Need Special Care
Black granite slabs, like other granite varieties, are made from natural stone and contain minerals that give them strength and character. However, darker colors tend to show streaks, smudges, and soap residue more easily under light. Therefore, granite countertop maintenance for black granite focuses on polishing and streak-free finishes.

Daily Cleaning Routine for Black Granite Countertops
1. Use a Microfiber Cloth and Mild Soap
Start by wiping the kitchen countertop or bathroom vanity with a soft microfiber cloth and a mixture of warm water and pH-neutral dish soap. This helps remove surface grime and oils without damaging the sealant.
- Avoid paper towels—they may leave lint or scratch the surface.
- Always wring out your cloth to prevent over-wetting.
2. Rinse Thoroughly with Clean Water
After wiping with soapy water, use a clean, damp cloth to rinse away any soap film. Soap residue can dull the polished surface of your granite countertop over time.
How to Polish Black Granite Countertops
1. Choose a Granite-Safe Polish
Use a specialized granite polish that is non-abrasive and formulated for natural stone. Spray a light mist and buff it in circular motions with a dry microfiber cloth.
2. Polish Weekly or Biweekly
Polishing once a week in a high-use kitchen, or every other week in a bathroom, keeps the dark granite surface looking sharp and enhances its reflective properties.
