What are the best methods for repairing scratches on polyethylene outdoor pet waste bins?

Polyethylene outdoor pet waste bins are durable but can develop surface scratches over time. For minor scratches, start by cleaning the surface with mild soap and water. Apply a plastic polish specifically designed for polyethylene using a soft cloth, rubbing in circular motions until scratches diminish. For deeper scratches, use a heat gun on low setting to gently melt the surface layer - keep the gun moving constantly to avoid damaging the plastic. Another effective method involves using a polyethylene repair compound that chemically bonds with the surface. After repair, apply UV-resistant protectant to prevent future damage. Regular maintenance with non-abrasive cleaners will help maintain the restored appearance. Always test methods on inconspicuous areas first and wear protective equipment during repairs.
