Mineral deposits on outdoor tables are a common issue caused by hard water, rain, or improper cleaning. These unsightly white stains can damage the surface over time if left untreated. Here are some practical tips to prevent and remove mineral buildup:

1. Regular Cleaning – Wipe down your table weekly with a mild soap and water solution to prevent mineral accumulation. Avoid harsh chemicals that may strip protective coatings.

2. Use a Protective Cover – When not in use, cover your outdoor table to shield it from rainwater, which often contains minerals that leave deposits.

3. Vinegar Solution for Stubborn Stains – Mix equal parts white vinegar and water to dissolve existing mineral deposits. Apply with a soft cloth, then rinse thoroughly.

4. Seal the Surface – Apply a sealant or wax designed for outdoor furniture to create a barrier against moisture and minerals.

5. Avoid Hard Water for Cleaning – If your tap water is hard, use distilled water for rinsing to prevent new deposits.

By following these steps, you can maintain a spotless outdoor table and extend its lifespan.
