Seeing those unsightly orange-brown rust stains on your concrete patio, especially under metal benches, can be frustrating. Fortunately, you can remove them with a few simple methods. Start by sweeping the area clean. For mild stains, create a paste with white vinegar and baking soda, apply it to the stain, let it sit for 30 minutes, then scrub with a stiff brush and rinse. For tougher stains, a commercial rust remover containing oxalic acid is highly effective—always follow the product's safety instructions, wearing gloves and goggles. Alternatively, a paste of lemon juice and salt works as a natural oxidizer. After treatment, rinse thoroughly with water. To prevent future stains, consider applying a concrete sealer or using plastic or rubber pads under the bench legs to break metal-to-concrete contact. Regular cleaning and quick attention to new rust spots will keep your concrete looking its best.
