Rust stains on concrete patios from outdoor furniture can be frustrating, but several effective methods can restore your surface. Begin with simple household solutions before moving to commercial products.
For mild stains, create a paste using lemon juice and salt. Apply generously to the stained area and let it sit for 30-60 minutes before scrubbing with a stiff brush. The acidic lemon juice breaks down rust while salt acts as a gentle abrasive.
White vinegar offers another natural solution. Soak rags in undiluted vinegar and place them directly on stains. Keep the rags moist for several hours, then scrub thoroughly. For persistent rust, try a baking soda paste mixed with hydrogen peroxide, which creates a fizzing action that lifts stains.
Commercial rust removers containing phosphoric or oxalic acid work effectively for severe cases. Always wear protective gloves and eyewear when using chemical cleaners. Apply according to manufacturer instructions, then rinse completely with water.
Prevent future rust stains by applying concrete sealant and using protective pads under furniture legs. Regular maintenance and quick attention to new stains will keep your patio looking pristine year-round.
Test any cleaning method on a small, inconspicuous area first to ensure it doesn't discolor or damage your concrete surface.
