How to Remove Stains from Stone Countertops
Learning how to remove stains from stone countertops is essential to keeping your kitchen or bathroom looking like new. Whether you have quartz, granite, marble, quartzite, or porcelain — stains can still appear over time. Fortunately, with the right techniques, you can restore your countertop’s shine safely and effectively.
Understanding Stains on Stone Countertops
Different stones react to liquids in unique ways. Quartz is non-porous and highly resistant to most stains. However, natural stones like granite, marble, and quartzite can absorb oils or acids if left untreated. Porcelain, while very dense, may still show surface marks if its finish is damaged.
Common types of stains include:
- Oil-based stains – from cooking oils, lotions, or greasy food.
- Organic stains – from coffee, tea, or wine spills.
- Rust stains – caused by metal objects left on damp surfaces.
- Water spots and mineral deposits – from hard water residue or improper cleaning.
How to Remove Stains from Stone Countertops Step-by-Step
1. Start with Gentle Cleaning
First, wipe the area using warm water, mild dish soap, and a microfiber cloth. Avoid using vinegar, bleach, or ammonia since these can dull or etch the stone surface. As a result, you’ll maintain both color and polish.
2. Apply a Poultice for Deep Stains
For stubborn spots, create a simple poultice. Mix baking soda and water (for oil-based stains) or baking soda and hydrogen peroxide (for organic stains) until it forms a thick paste. Spread it over the affected area, cover it with plastic wrap, tape the edges, and let it sit for 24–48 hours. Then, rinse and dry completely.
3. Rinse and Dry Thoroughly
After cleaning, rinse the countertop with clean water and dry it fully. Using a microfiber cloth helps prevent streaks and restores shine.
4. Seal Natural Stone Surfaces Regularly
Granite, marble, and quartzite countertops should be sealed every one to two years. This protective layer repels liquids and prevents new stains from forming. In addition, sealing makes day-to-day cleaning much easier.
5. Call a Professional for Deep Damage
If a stain won’t budge or if etching has occurred, it’s time to call Stone Valley’s countertop repair experts. Our trained team can safely refinish and restore your countertop — often in just one day.
How to Prevent Stains on Stone Countertops
Prevention is the best cure. By maintaining your countertop properly, you can avoid future stains altogether.
- Wipe spills right away — especially coffee, wine, or juice.
- Use cutting boards and coasters to reduce oil and acid exposure.
- Never place hot pots directly on your countertop to prevent burn marks.
- Clean with a pH-balanced stone cleaner instead of harsh products.
