Discovering graffiti on your urban benches can be frustrating, but removing it doesn't have to mean damaging the finish. The key is acting quickly and using the right approach for your bench material.
For metal benches, start with the gentlest method first. Mix warm water with a few drops of dish soap and scrub with a soft-bristled brush. For stubborn marks, isopropyl alcohol or citrus-based graffiti removers are effective yet gentle on powder-coated finishes. Always test any cleaner on a small, hidden area first.
Wooden benches require more care. Avoid harsh chemicals that can strip protective seals or stain the wood. A solution of baking soda and water often works wonders. Apply the paste, let it sit for 10 minutes, then gently scrub with a nylon brush. For painted wood, mineral spirits can remove spray paint without damaging the underlying coat.
Concrete and stone benches can handle stronger approaches. Pressure washing at low PSI (under 1500) with hot water effectively removes fresh graffiti. For older stains, use a biodegradable graffiti remover specifically formulated for masonry surfaces.
Always rinse thoroughly after cleaning and consider applying a protective anti-graffiti coating once the bench is spotless. This clear sealant makes future cleanups much easier. Regular maintenance and prompt graffiti removal are your best defenses against permanent damage to your urban furniture.
