Keeping the concrete bases of our urban benches clean and well-maintained is essential for both aesthetics and longevity. Here's a practical guide on how to do it effectively.
For routine cleaning, a simple mix of mild dish soap and warm water with a stiff-bristled brush works wonders for removing everyday dirt and grime. Rinse thoroughly with a garden hose. For tougher stains like graffiti, bird droppings, or gum, use a specialized concrete cleaner or a paste of baking soda and water. Apply, let it sit, and scrub gently.
For deep cleaning, a low-pressure power washer (under 1500 PSI) is highly effective. Hold the nozzle at least 12 inches from the surface to avoid etching the concrete. Always test a small, inconspicuous area first.
Once or twice a year, inspect the base for cracks or chips. Small cracks can be filled with a concrete patching compound. Applying a penetrating concrete sealer after cleaning and repair is a crucial step. This sealant protects against moisture, stains, and freeze-thaw damage, significantly extending the bench's life.
Regular maintenance not only keeps our public spaces welcoming but also ensures these benches remain a durable part of our urban landscape for years to come.
