Outdoor tables often develop unsightly support stains from metal brackets, moisture, or prolonged contact with uneven surfaces. These stubborn marks can be frustrating, but with the right approach, you can restore your table's appearance.

For light stains, start by mixing equal parts white vinegar and water. Apply the solution with a soft cloth, scrubbing gently in circular motions. Vinegar's acidity helps break down mineral deposits and rust stains. Rinse thoroughly with clean water afterward.

For tougher stains, create a paste using baking soda and hydrogen peroxide. Spread it over the affected area and let it sit for 15-20 minutes before scrubbing with a non-abrasive brush. This combination works well on organic stains and mild rust.

Metal support stains may require specialized rust removers. Look for products containing oxalic acid, which effectively dissolves rust without damaging most table surfaces. Always test cleaners on an inconspicuous area first.

Prevent future stains by applying a protective wax or sealant to your table's surface. Regularly clean and dry the area where supports contact the table, and consider using protective pads between metal and table surfaces.

For wooden tables, sanding may be necessary for deep stains. Start with fine-grit sandpaper (220 grit) and work your way to finer grits for a smooth finish. Always follow with appropriate wood treatment to protect the exposed surface.

With these methods, your outdoor table can look clean and well-maintained throughout all seasons. Regular care will minimize staining and extend your furniture's lifespan.
