Powder coating is one of the most durable finishes available for outdoor furniture, but even this tough surface requires proper care to maintain its appearance and protective qualities over time. Regular maintenance of your powder coated benches will not only keep them looking beautiful but will significantly extend their lifespan, protecting your investment for years to come.
For routine cleaning, a simple and gentle approach is best. Start by removing loose debris like leaves, dirt, and pollen with a soft-bristled brush or by rinsing with a garden hose. For a deeper clean, create a solution of warm water and a few drops of mild, non-abrasive dish soap. Avoid harsh chemicals, abrasive cleaners, and solvents at all costs, as they can permanently damage the powder coat finish. Use a soft sponge or cloth to gently wipe the surface, then rinse thoroughly with clean water. To prevent water spots, dry the bench with a soft, microfiber towel.
For tougher grime, such as bird droppings, tree sap, or pollution residue, a more targeted approach may be necessary. Apply your mild soapy solution and allow it to sit on the affected area for a few minutes to loosen the debris. Gently agitate with a soft brush if needed, but never use steel wool, scouring pads, or harsh brushes that can scratch the surface. Stubborn stains might require a specialized powder coat cleaner, but always test any new product on a small, inconspicuous area first.
While powder coating is robust, certain cleaning methods should be strictly avoided. Never use a high-pressure washer on a high-power setting, as the intense pressure can chip or peel the finish. Keep the nozzle at least 12 inches away and use a wide-angle tip if you must use a pressure washer. Also, refrain from using waxes or silicone-based polishes, as they can create a sticky film that attracts more dirt.
The frequency of cleaning depends on your local environment. Benches in coastal areas may need more frequent rinsing to remove salt, while those under trees will require regular cleaning of organic matter. A simple visual inspection every few months will tell you when it's time for a clean. By following these straightforward steps, you can ensure your powder coated outdoor benches remain vibrant, protected, and a welcoming part of your outdoor space for a long time.
