Urban outdoor furniture endures a constant assault of grime, pollution, bird droppings, and weather. Restoring it requires a methodical approach. First, remove loose debris with a stiff brush. For general cleaning, a solution of warm water and mild dish soap applied with a scrub brush is effective for metals, plastics, and treated woods. For stubborn stains and concrete furniture, a low-pressure power washer can be transformative, but always test on an inconspicuous area first to prevent damage.
For biological growth like mold or mildew, a diluted vinegar solution or a commercial eco-friendly cleaner is ideal. Avoid harsh chemicals like bleach on metals as they can accelerate corrosion. Always rinse thoroughly with clean water after cleaning. To protect furniture long-term, consider applying a protective sealant or wax suitable for the material after it is completely dry. Establishing a regular cleaning schedule, such as a thorough clean each season, prevents grime from building up and makes maintenance far easier, ensuring your public benches, tables, and chairs remain inviting and durable in the cityscape.
