Keeping your thermoplastic-coated outdoor benches looking great for years is easier than you think. The key is regular, gentle care. Start by giving your bench a weekly rinse with a garden hose to wash away loose dirt, pollen, and bird droppings. For a deeper monthly clean, mix a solution of mild dish soap and lukewarm water. Use a soft-bristled brush or a non-abrasive sponge to gently scrub the surface, then rinse thoroughly. Avoid harsh chemicals, abrasive pads, or pressure washers, as these can damage the durable thermoplastic coating.
For stubborn stains like tree sap or grease, a specialized plastic cleaner is your best bet. Always test any new cleaner on a small, inconspicuous area first. To maintain the coating's integrity and color, apply a UV-protectant spray designed for plastics once or twice a year. This simple step helps prevent fading and brittleness from sun exposure.
During harsh winter months or extended periods of non-use, consider covering the bench with a breathable, waterproof cover. If that's not possible, try to position it in a somewhat sheltered spot. By following this simple routine—regular rinsing, gentle soap cleaning, and annual UV protection—you’ll significantly extend the life and beauty of your thermoplastic-coated benches, ensuring they remain a welcoming spot in your garden or patio for a long time.
