Many homes have exterior or screen doors made from aluminium. Aluminium doors are inexpensive, sturdy and a great choice for most homeowners. Aluminium exterior doors can collect dirt, debris and easily show grime. When aluminium doors become dirty and require cleaning, do not use everyday household cleansing products. Some cleansers have harsh chemicals or abrasives that can damage the finish of an aluminium door. Aluminium doors are easy to clean when you know how to clean them and what products to use.
Clean the aluminium door with simple soap and water. Mix a few drops of gentle dish soap with warm water in the sink or a bucket. Wipe the aluminium door with a rag soaked in the mixture. This will remove the surface dirt from the door and reveal any underlying areas that need further cleaning.
Rinse the door with a water hose or clean water to remove any loose dirt and the soap remnants. Do not power spray the door, as this could harm the aluminium; gently rinse the door with the water.
Combine equal parts water and white vinegar into a spray bottle. Spray the mixture onto any remaining spots or dirt on the door and spray the mixture onto a clean, dry cloth.
Wipe or scrub lightly to remove stains or dirty areas on the door with the damp cloth. The acidity of the solution will break down the dirt and grime left after cleaning with dish soap without damaging the aluminium or door finish.
Rinse the door with a water hose or clean water to remove any remaining dirt and vinegar mixture from the door.
Lemon juice can substitute for white vinegar if desired. The vinegar and water mixture can be stored in the spray bottle for later use.
Never use an abrasive such as SOS or brillo Pads. These abrasives will leave scratches in aluminium. Use a soft cloth to scrub aluminium to prevent damage.
