Bird droppings on metal urban benches are not just unsightly - they can be acidic and damage the finish if left untreated. The key to successful removal is acting quickly and using gentle methods that preserve the bench's protective coating.
Start by gathering your supplies: warm water, mild dish soap, a soft-bristled brush (like a nylon brush or even an old toothbrush), a spray bottle, and clean microfiber cloths. Avoid harsh tools like wire brushes or abrasive scrubbers that can scratch the metal surface.
Begin by spraying the affected area with plain warm water to loosen the droppings. Let it sit for a minute to soften the deposit. Create a cleaning solution by mixing a few drops of mild dish soap with warm water in your spray bottle. Spray this solution generously over the droppings and allow it to sit for 5-10 minutes to break down the mess.
Gently scrub the area with your soft-bristled brush, using circular motions. Start from the edges and work toward the center to prevent spreading the mess. For stubborn deposits, you may need to reapply the soapy solution and let it sit longer before scrubbing again.
Once the droppings are removed, thoroughly rinse the area with clean water to eliminate any soap residue. Soap left on the surface can attract more dirt over time. Finally, dry the bench completely with a clean microfiber cloth to prevent water spots and potential rust formation.
For particularly stubborn or dried-on droppings, you can create a paste from baking soda and water. Apply it to the affected area, let it sit for 15-20 minutes, then gently scrub and rinse. Always test any cleaning method on a small, inconspicuous area first to ensure it doesn't affect the finish.
Regular maintenance is your best defense against permanent damage. Wiping down benches weekly can prevent droppings from hardening and becoming more difficult to remove. With this gentle approach, you can keep urban benches looking their best while protecting their long-term durability.
