Dealing with permanent marker graffiti on public trash cans is frustrating, but don't worry - several common household items can effectively remove it without damaging the metal surface.
First, try rubbing alcohol or hand sanitizer. Apply generously to a cloth and scrub in circular motions. The alcohol breaks down the marker's pigments. For stubborn stains, create a paste with baking soda and water. Apply, let sit for 5 minutes, then scrub with a stiff-bristled brush.
Magic erasers are remarkably effective too. Dampen one and scrub firmly. The micro-abrasion lifts the ink from the metal's pores. For extensive graffiti, consider using a citrus-based graffiti remover spray, following product instructions carefully.
Always test any method on a small, inconspicuous area first. After cleaning, rinse thoroughly with water and dry the surface to prevent water spots. Regular maintenance keeps community trash cans looking clean and deters future vandalism.
