What are the best ways to restore the color of weathered polypropylene?

Weathered polypropylene often loses its vibrant color due to prolonged exposure to sunlight, dirt, and environmental factors. Restoring its original appearance requires a combination of cleaning, protection, and specialized treatments. Start by thoroughly cleaning the surface with a mild detergent and a soft brush to remove dirt and grime. For stubborn stains, use a specialized plastic cleaner. Next, apply a UV protectant to shield the material from further sun damage. If the discoloration is severe, consider using a plastic restorer or dye designed for polypropylene. Regular maintenance, such as applying a protective coating, can help preserve the color and extend the lifespan of your polypropylene items. By following these steps, you can effectively restore and maintain the vibrant color of weathered polypropylene.
