Teak outdoor tables are prized for their durability and natural beauty, but over time, they can develop stubborn girder stains from metal fixtures or environmental exposure. If you're wondering how to remove these unsightly marks, follow these proven methods to restore your table's appearance.

1. Identify the Stain Type: Girder stains often appear as dark streaks caused by metal oxidation or rust. Check if the stain is superficial or deeply embedded.

2. Gentle Cleaning Solution: Mix warm water with mild dish soap and a teaspoon of white vinegar. Use a soft-bristle brush or sponge to scrub the stained area gently. Avoid harsh chemicals that can damage teak’s natural oils.

3. Baking Soda Paste: For tougher stains, create a paste of baking soda and water. Apply it to the stain, let it sit for 10-15 minutes, then scrub lightly and rinse.

4. Oxalic Acid Treatment: If stains persist, use a teak cleaner containing oxalic acid, which helps break down rust and metal marks. Follow the product instructions carefully.

5. Rinse and Protect: After cleaning, rinse the table thoroughly with clean water and let it dry. Apply teak oil or sealant to protect the wood from future stains.

Regular maintenance, like wiping down your teak table after use and keeping it covered when not in use, can prevent girder stains from forming. With these steps, your teak outdoor table will look as good as new!
