Park chairs in public spaces undergo regular cleaning to ensure hygiene and longevity. Common methods include pressure washing to remove dirt and debris, followed by disinfection using eco-friendly solutions to kill germs. Some cities employ specialized cleaning crews with portable steam cleaners for deep sanitation, while others rely on biodegradable detergents and manual scrubbing. In high-traffic areas, chairs may be cleaned daily, while less frequented spots receive weekly maintenance. Weather-resistant materials like powder-coated metal or treated wood are often chosen to simplify upkeep. Advanced systems even incorporate UV light sterilization in some urban parks. Proper drainage designs also prevent water accumulation, reducing mold risks. These practices balance public health needs with environmental sustainability.
