To remove rust spots that have already formed on your old urban outdoor furniture, you can use several effective DIY methods. First, safety is key: wear gloves and eye protection. For light surface rust, start by scrubbing the area with a wire brush or coarse steel wool to loosen the flakes. Then, create a paste using baking soda and water or white vinegar, apply it to the rusted spots, and let it sit for an hour before scrubbing again. Rinse thoroughly with water and dry the metal completely.
For more stubborn rust, a commercial rust converter or remover can be applied according to the product instructions. These chemicals react with the rust, stabilizing it and often priming the surface for painting. After any treatment, it is crucial to neutralize and clean the area. Once the metal is clean and dry, apply a rust-inhibiting primer and a suitable outdoor paint or sealant to protect the furniture from future moisture and corrosion. Regular cleaning and applying a fresh protective coat every few years will help prevent rust from returning, extending the life of your urban outdoor pieces.
