Park chairs are a common sight in outdoor spaces, often exposed to food spills and stains. To handle food stains effectively, start by wiping the surface immediately with a damp cloth to prevent the stain from setting. For stubborn stains, mix mild soap with water and gently scrub the area using a soft brush. Avoid harsh chemicals that may damage the chair's material. For metal or plastic chairs, a vinegar-water solution can work wonders. Regular maintenance, such as rinsing chairs with water after use, helps prevent long-term staining. By following these simple steps, you can keep park chairs clean and inviting for everyone.
