Discovering graffiti on your powder-coated outdoor benches can be frustrating, but don't worry - with the right approach you can restore them to their original condition. Powder-coated surfaces are durable but require specific cleaning methods to avoid damaging the protective finish. Start by testing any cleaning solution on a small, inconspicuous area first.
For fresh graffiti, begin with the gentlest approach: mix warm water with a few drops of dish soap and scrub with a soft-bristled brush or sponge. Rinse thoroughly. If this doesn't work, move to isopropyl alcohol or non-acetone nail polish remover applied with a soft cloth - these are often effective against spray paint without harming the powder coating.
For stubborn graffiti, create a paste from baking soda and water or use a specialized graffiti remover designed for powder-coated surfaces. Always follow product instructions carefully and wear protective gloves. Avoid abrasive tools like steel wool or harsh chemicals like acetone that can permanently damage the finish.
After graffiti removal, wash the entire bench with soapy water, rinse completely, and dry with a soft cloth. Consider applying a protective wax designed for powder-coated surfaces to create a barrier against future vandalism. With these methods, your benches should look clean and vibrant again without compromising their weather-resistant properties.
