Mineral stains on outdoor tables are a common issue caused by hard water, rain, or improper cleaning. These unsightly white or gray marks can dull the appearance of your patio furniture, but with the right techniques, you can prevent and even remove them.

1. Use a Protective Cover – When not in use, cover your outdoor table with a waterproof, UV-resistant cover. This shields it from rain and hard water deposits that cause mineral buildup.

2. Clean Regularly – Wipe down your table weekly with a mild soap and water solution. Avoid harsh chemicals, as they can strip protective finishes and worsen staining.

3. Dry Thoroughly – After cleaning or rain, dry the surface with a soft cloth to prevent water spots from forming.

4. Apply a Sealant – For wood, metal, or plastic tables, use a sealant or wax designed for outdoor furniture. This creates a barrier against moisture and minerals.

5. Vinegar Solution for Stubborn Stains – If stains appear, mix equal parts white vinegar and water, apply to the affected area, and gently scrub with a soft brush. Rinse well afterward.

By following these steps, you can keep your outdoor table stain-free and extend its lifespan. Regular maintenance is key to preserving its beauty and functionality.
