Nothing ruins the look of your outdoor space like stubborn rust stains on your patio. Whether from metal furniture, garden tools, or well water, those unsightly orange-brown marks can be frustrating to remove—especially if left untreated for too long.

Key Takeaways
- Act fast—older rust stains are harder to remove.
- Natural acids like vinegar or lemon juice break down rust effectively.
- Scrubbing tools matter: use stiff-bristle brushes for concrete.
- Prevent future stains by sealing your patio and storing metal items properly.
1. Dish Soap and Warm Water (For Light Stains)
For fresh or minor rust stains, start with a simple dish soap solution. Mix 2 tablespoons of dish soap (like Dawn) with a gallon of warm water. Apply to the stain, let it sit for 15 minutes, then scrub with a stiff-bristle brush. Rinse thoroughly. This method works well for surface-level stains and is safe for all patio materials, including concrete and pavers.
2. White Vinegar and Baking Soda Paste
Use vinegar or lemon juice with baking soda; scrub and rinse. Create a paste by mixing equal parts white vinegar and baking soda. Apply it to the stain, let it sit for 30 minutes, then scrub gently. The acidic vinegar dissolves rust, while baking soda acts as a mild abrasive. Rinse with water afterward. Note: Avoid using vinegar on delicate surfaces like natural stone.
3. Lemon Juice and Salt Scrub
For a natural alternative, squeeze fresh lemon juice over the stain and sprinkle coarse salt on top. Let it sit for 1-2 hours before scrubbing. The citric acid in lemons breaks down rust, while salt provides scrubbing power. This works especially well on smaller stains.
4. Commercial Rust Removers (For Severe Stains)
For deep-set or old rust stains, consider a commercial rust remover like CLR or Bar Keepers Friend. Follow the manufacturer’s instructions, and always test in an inconspicuous area first. Wear gloves and ensure proper ventilation when using chemical cleaners.
5. Pressure Washing (For Large Areas)
If your entire patio has rust discoloration, a pressure washer (1,500–3,000 PSI) can help. Use a wide-angle tip to avoid damaging the surface. Combine this with a cleaning solution for best results.
