Keeping your thermoplastic-coated urban benches clean and well-maintained is simpler than you might think. Here's your practical, step-by-step guide.
For daily or weekly upkeep, a simple routine works best. Use a soft-bristled brush or a cloth with a mild soap solution—think a few drops of dish soap in a bucket of warm water. Gently scrub the surface to remove common dirt, bird droppings, and pollen. Always rinse thoroughly with clean water. Avoid harsh abrasive pads or stiff metal brushes, as they can scratch the coating.
When you encounter tougher stains like gum, grease, or deep-set grime, act promptly. For chewing gum, harden it with an ice pack and then carefully scrape it off with a plastic putty knife. For grease, a specialized citrus-based degreaser is effective; apply it, let it sit briefly, then scrub and rinse. For general deep cleaning, a low-pressure power washer (under 1500 PSI) from a safe distance of about 12-18 inches is highly effective. Always test any cleaner on a small, inconspicuous area first.
Graffiti is a common urban challenge. The key is immediate action. Use a graffiti remover specifically formulated for coated surfaces. Apply it according to the product instructions, often letting it dwell to break down the paint, then wipe or rinse it away. Never use paint thinners, acetone, or aggressive solvents, as they will permanently damage the thermoplastic coating.
Long-term maintenance is about prevention and inspection. Conduct seasonal checks for any chips, cracks, or signs of wear in the coating. Address minor damage quickly with a matching thermoplastic touch-up paint to prevent moisture from reaching the metal substrate underneath. During winter, avoid using corrosive rock salt or ice melters directly on the bench; use plastic shovels for snow removal instead.
By following these straightforward steps—regular gentle cleaning, prompt stain treatment, careful graffiti removal, and seasonal touch-ups—you can significantly extend the life and beauty of your thermoplastic-coated benches, ensuring they remain a welcoming public asset for years to come.
