To remove tea stains from stainless steel, scrub the area with a paste of baking soda and water, then rinse and dry thoroughly for a spotless finish.
Tea stains on stainless steel can be frustrating, whether they’re on your favorite travel mug, kitchen appliances, or pool equipment. These stubborn brownish spots are often caused by tannins in tea reacting with the metal surface. Fortunately, with the right techniques, you can restore your stainless steel to its original shine.
Why Tea Stains Stainless Steel
Tea contains tannic acid that reacts with the chromium in stainless steel, creating those unsightly brown marks. This is especially common in coastal areas where salt air accelerates the staining process. The good news? These stains are purely cosmetic and won’t damage your stainless steel items.
Prevention Tips
- Rinse tea cups and containers immediately after use
- Dry stainless steel thoroughly after washing
- For outdoor items, rinse weekly with fresh water
Effective Tea Stain Removal Methods
1. Vinegar Solution
White vinegar is one of the most effective natural cleaners for stainless steel:
- Fill a spray bottle with undiluted white vinegar
- Spray directly on stained areas
- Let sit for 5-10 minutes
- Scrub gently with a soft cloth or non-abrasive sponge
- Rinse thoroughly with warm water
2. Baking Soda Paste
For tougher stains, make a paste with baking soda and water:
| Ingredients | Ratio |
|---|---|
| Baking soda | 3 parts |
| Water | 1 part |
Apply the paste with a soft cloth, rub in circular motions, then rinse. For extra cleaning power, check out our guide on maintaining stainless steel appliances.
3. Lemon Juice Method
The citric acid in lemons works wonders on tea stains:
- Cut a lemon in half
- Rub directly on stained areas
- Let sit for 2-3 minutes

Special Cases
For Pool Equipment
Coastal areas often experience “tea staining” on stainless steel pool components. Regular maintenance is key:
- Rinse with fresh water weekly
- Use a vinegar solution monthly
- Dry thoroughly after cleaning
For Cookware
Stained stainless steel pans can be revived by boiling a vinegar-water solution (1:1 ratio) for 10 minutes. This method also works well for stainless steel coffee carafes.
What NOT to Use
Avoid these common mistakes when cleaning stainless steel:
- Steel wool (can scratch surfaces)
- Bleach (can damage the metal)
- Harsh chemical cleaners
- Scouring pads (unless specifically designed for stainless steel)
