Silicone stains on park chairs can be stubborn, but with the right approach, they can be effectively removed. Start by scraping off excess silicone with a plastic scraper or blunt knife. Avoid using sharp tools to prevent damaging the chair's surface. Next, apply a silicone remover or rubbing alcohol to a cloth and gently rub the stained area. For tougher stains, a mixture of baking soda and water can be used as a mild abrasive. Rinse the area thoroughly with water and dry it with a clean cloth. Regular maintenance and prompt cleaning can help keep park chairs looking their best. Always test any cleaning solution on a small, inconspicuous area first to ensure it doesn’t damage the material.
