Keeping your aluminum outdoor benches clean and well-maintained is key to ensuring they last for many seasons. Aluminum is prized for its durability and resistance to rust, but it can still accumulate dirt, grime, and even a chalky white substance called oxidation. With the right approach, you can easily restore their shine and protect your investment. Here is a simple, step-by-step guide.
First, gather your supplies. You will need a bucket of warm water, a mild dish soap or a dedicated aluminum cleaner, a soft-bristled brush or a non-abrasive sponge, a garden hose, and a soft cloth for drying. For benches with significant oxidation, a mixture of white vinegar and water or a commercial aluminum restoration product may be necessary. Always have a coat of automotive wax or a protective sealant on hand for the final step.
Start with a basic clean. Mix a few drops of dish soap into your bucket of warm water. Use your soft-bristled brush or sponge to gently scrub the entire surface of the bench, paying special attention to crevices and detailed areas where dirt loves to hide. Avoid using steel wool or harsh abrasive pads, as these will scratch the soft surface of the aluminum.
Next, rinse thoroughly. Use your garden hose to wash away all the soapy water and loosened dirt. Ensure no soap residue remains, as this can attract more dirt later.
For tougher stains or oxidation, you need a deeper clean. If you see a white, powdery film on the surface, that's oxidation. Create a cleaning solution of one part white vinegar to one part water. Apply it to the affected areas with a sponge and let it sit for 5-10 minutes. Then, gently scrub with your soft brush and rinse completely. For stubborn cases, a commercial aluminum cleaner specifically designed to remove oxidation is highly effective. Always follow the product instructions and wear gloves.
The most crucial step for long-term maintenance is to dry and protect. After cleaning and rinsing, use a soft, dry cloth to wipe the bench completely dry. This prevents water spots. Once the bench is clean and dry, apply a thin, even layer of a non-abrasive automotive wax or a protective sealant made for metal furniture. This wax acts as a barrier against moisture, UV rays, and pollutants, significantly slowing down the oxidation process and making future cleanups much easier.
By following these simple steps—regular cleaning, tackling oxidation promptly, and applying a protective coat—your aluminum outdoor benches will remain a beautiful and sturdy part of your outdoor living space for years to come.
