Hard water marks on outdoor tables can be frustrating, but with the right care, you can keep your furniture looking pristine. Here are some effective methods to prevent and remove these stubborn stains:

1. Use a Protective Cover: Shield your table from rain and sprinkler systems by using a waterproof cover. This minimizes exposure to mineral-rich water that causes stains.

2. Regular Cleaning: Wipe down the table with a soft cloth and mild soapy water after rain or spills. Avoid letting water sit for long periods.

3. Vinegar Solution: For existing hard water stains, mix equal parts white vinegar and water. Gently scrub the affected area, then rinse thoroughly.

4. Seal the Surface: Apply a protective sealant or wax designed for outdoor furniture. This creates a barrier against water absorption and mineral deposits.

5. Dry Immediately: After cleaning or rain, dry the table with a microfiber cloth to prevent water spots from forming.

By following these steps, you can maintain a spot-free outdoor table and enjoy its beauty for years to come.
