How to Clean Granite: A Comprehensive Guide
Granite is a popular choice for kitchen countertops and bathroom vanities due to its durability, beauty, and low maintenance. However, like any other surface, it requires regular cleaning to keep it looking its best. This comprehensive guide will walk you through the process of cleaning granite, addressing common issues, and providing tips for maintaining its natural shine.
Understanding Granite Sealing
Before we dive into cleaning, it's crucial to understand that granite is a porous natural stone. This means it can absorb liquids, which can lead to staining if not properly sealed. It's recommended to seal your granite surfaces every 1-5 years, depending on the sealer used and the level of traffic the surface receives. Always ensure your granite is sealed before cleaning to prevent potential damage.
Daily Cleaning: The Basics
For daily cleaning, use a mild dish soap and warm water solution. Avoid using harsh chemicals like bleach, ammonia, or vinegar, as they can damage the sealant and cause etching. Here's a simple step-by-step process:

- Mix a few drops of mild dish soap with warm water.
- Dip a soft cloth or sponge into the solution.
- Wipe the granite surface gently, ensuring you cover the entire area.
- Rinse the surface with clean water using a damp cloth.
- Dry the surface thoroughly with a clean, dry cloth to prevent water spots.
Removing Tough Stains
Despite sealing, stains can occur. Here's how to tackle some common ones:
Oil-Based Stains
For oil-based stains like cooking grease or motor oil, sprinkle baking soda onto the stain, let it sit for 15-30 minutes, then scrub gently with a soft brush. Wipe off the paste with a damp cloth and dry the surface.
Mineral Stains
Mineral stains, often caused by hard water, can be removed using a poultice. Apply the poultice to the stain, let it sit for 24-48 hours, then vacuum off the residue and wipe clean.

Rust Stains
Rust stains can be removed using a mixture of hydrogen peroxide (3%) and a few drops of ammonia. Apply the solution to the stain, let it sit for 15-30 minutes, then scrub gently and wipe clean.
Polishing and Maintaining the Shine
To restore the natural shine of your granite, use a granite polish or a sealant with polish built-in. Apply the polish according to the manufacturer's instructions, usually involving spraying or applying the polish, letting it sit, then buffing it off with a clean, dry cloth.
Preventive Care
To keep your granite looking its best, follow these preventive care tips:
- Wipe up spills immediately.
- Use coasters for glasses to prevent water rings.
- Avoid placing hot pots or pans directly on the surface.
- Use cutting boards to protect the surface from knife scratches.
- Clean your granite regularly to prevent dirt buildup.
Regular cleaning and maintenance will ensure your granite surfaces remain beautiful and functional for years to come. Always remember to test any cleaning solution on a small, hidden area first to ensure it doesn't cause discoloration or damage.
