Keeping the plastic slats on your outdoor benches clean is key to maintaining their appearance and longevity. The good news is, it's a straightforward process. For routine cleaning, mix a mild dish soap with warm water. Use a soft-bristled brush or a non-abrasive cloth to gently scrub the slats, removing dirt, pollen, and general grime. Rinse thoroughly with a garden hose. For tougher stains like mildew or bird droppings, a solution of white vinegar and water or a specialized plastic cleaner can be effective. Always test any cleaner in a small, inconspicuous area first.
Avoid using harsh chemicals, abrasive scrubbers, or steel wool, as these can scratch and dull the plastic surface. For a deep clean, a low-pressure power washer can be excellent, but hold the nozzle at least 12 inches away and use a wide fan tip to prevent damage. For maintenance, consider applying a protectant spray designed for outdoor plastics once or twice a year. This helps shield the slats from UV rays and can make future cleaning easier. Regular care will keep your benches looking fresh and extend their life for many seasons of enjoyment.
