How to Remove Tea Stains from Granite Countertops – Easy & Effective Methods

Granite countertops are a favorite in kitchens due to their durability, elegance, and natural beauty. However, their porous surface can make them prone to stains, particularly from dark liquids like tea. Whether it’s a fresh spill or a stubborn stain that has set over time, knowing how to remove tea stains from granite is essential to maintain its pristine appearance. In this guide, we’ll cover effective cleaning methods, solutions for stubborn stains, and prevention tips to keep your granite countertops looking flawless.

Can You Remove Tea Stains from Granite?

Yes, tea stains can be removed from granite, but results depend on the age and depth of the stain. Fresh spills are easier to clean, while older stains, especially from dark teas like oolong, may require specialized methods. Granite’s porous structure allows liquids to seep in, so acting quickly and using granite-safe cleaners is crucial. Avoid acidic or abrasive products that could etch or scratch the surface.

Quick Methods to Remove Fresh Tea Stains

If you notice the tea spill immediately, the following methods can help prevent long-term staining:

1. Mild Dish Soap and Warm Water

A simple solution of mild dish soap and warm water is often enough to remove fresh tea stains:

1. Mix a few drops of mild dish soap in warm water.
   
2. Dampen a soft cloth or sponge in the solution.
   
3. Gently wipe the stained area.
   
4. Rinse with clean water and dry with a microfiber cloth.
   

Tip: Avoid scrubbing aggressively to prevent scratches.

2. Baking Soda Paste for Light Stains

For light tea stains:

1. Mix baking soda with water to form a thick paste.
   
2. Apply the paste to the stained area.
   
3. Cover with plastic wrap and let it sit for 24 hours.
   
4. Wipe clean with a soft damp cloth.
   

This method works well for stains that haven’t penetrated deeply.

3. Use a Soft Cloth or Sponge

Always use soft tools like microfiber cloths or non-abrasive sponges. Steel wool, scouring pads, or rough brushes can scratch granite surfaces.

Removing Old or Stubborn Tea Stains

For stains that have set over time, especially darker teas like oolong, simple methods may not work. Here are more advanced solutions:

1. Diatomaceous Earth and Hydrogen Peroxide Poultice

If a baking soda poultice fails:

1. Mix food-grade hydrogen peroxide with diatomaceous earth to make a thick paste.
   
2. Apply the poultice over the stained area.
   
3. Cover with plastic wrap and let it sit for 24–48 hours.
   
4. Remove the poultice and gently rinse the granite with warm water.
   
5. Repeat if necessary.
   

Why it works: Baking soda dissolves too easily to pull deep stains out, while diatomaceous earth is stable and helps hydrogen peroxide wick the stain out of the granite effectively.

Pro tip: Always test a small, hidden area first to ensure compatibility with your granite type.

2. Commercial Granite Cleaners

For stubborn stains that persist, use a pH-neutral, granite-safe cleaner designed for natural stone. Follow the manufacturer’s instructions to prevent damage.

Homemade Remedies for Tea Stains on Granite

Several DIY options can also be effective:

Vinegar-Free Cleaners

Avoid vinegar or lemon juice directly, as acids can etch granite. Safe alternatives include:

• Mild dish soap + warm water
  
• Hydrogen peroxide for deep stains (cautiously applied)
  

Lemon Juice Considerations

Lemon juice can help with light stains, but always test on a small area and rinse thoroughly afterward to avoid surface etching.

Preventing Tea Stains on Granite Countertops

Prevention is often easier than removal. Protect your granite with these tips:

Wipe Spills Immediately

Act quickly—longer contact allows stains to penetrate. Keep a cloth or sponge handy.

Use Coasters and Trivets

Place coasters under mugs and trivets under teapots to reduce direct contact with the granite surface.

Seal Granite Regularly

Sealing creates a protective layer that prevents liquids from penetrating. Most granite surfaces should be sealed once a year, but high-use areas may require more frequent sealing.

Tips for Maintaining a Stain-Free Granite Countertop

Daily Cleaning Routine

Wipe countertops daily with a soft cloth and mild soap solution to remove oils, dust, and beverage residues.

Avoid Harsh Chemicals

Steer clear of ammonia, bleach, or acidic cleaners. Use pH-neutral, non-abrasive cleaners designed for natural stone.

Regular Professional Polishing (Optional)

Professional polishing every few years can restore shine and help minimize minor stains and scratches.

FAQs About Tea Stains on Granite

Can I use bleach to remove tea stains?
No. Bleach can discolor or damage granite. Stick to mild dish soap, baking soda, or commercial granite cleaners.

How often should I seal granite countertops?
Typically once a year, but check with your countertop manufacturer for recommendations.

What if a tea stain has been on granite for months?
For stubborn stains, try a diatomaceous earth + hydrogen peroxide poultice or consult a professional granite cleaner.

Conclusion

Tea stains on granite countertops can be frustrating, but with the right methods, they are completely manageable. Quick cleaning, proper poultice techniques, and preventive care will help maintain your granite’s natural beauty. For stubborn stains like oolong tea, a stable poultice using diatomaceous earth and hydrogen peroxide is often the most effective solution. Regular maintenance and sealing ensure that your granite remains stain-free, elegant, and durable for years to come.
