Aluminum outdoor benches are prized for their durability and resistance to rust, but they still require regular care to look their best and last for years. The good news? Maintenance is straightforward. Start with regular cleaning. Every few weeks, or after storms, wash the bench with a mixture of mild dish soap and warm water using a soft cloth or sponge. This removes dirt, pollen, and bird droppings that can dull the surface. For tougher grime, a non-abrasive cleaner is safe. Rinse thoroughly with a hose.
It's crucial to check for and address any damage to the powder coating—the colored finish that protects the metal. If you find chips or scratches, clean the area, let it dry, and apply a touch-up paint designed for aluminum to prevent oxidation. While aluminum won't rust, it can develop a chalky white oxidation layer if the coating is severely compromised.
To protect your investment, consider applying a protective automotive wax or a specific UV-protectant sealant for metal furniture once or twice a year. This adds a barrier against UV rays and moisture, keeping the finish vibrant. During harsh winter months, if possible, store benches in a shed or garage, or use quality furniture covers. Avoid placing them directly under trees that drip sap.
Finally, tighten any bolts or screws annually, as movement can loosen them over time. By following these simple steps—cleaning, inspecting the finish, applying protective products, and seasonal care—you ensure your aluminum benches remain beautiful, comfortable, and functional for countless seasons outdoors.
