Aluminum storm doors normally protect an inside door from outside elements such as dust, dirt, wind and rain. Over time, the aluminum's outside finish dulls and looks old. Proper cleaning will restore its original shine. Aluminum cleaners that are sold at most auto stores and used on aluminum wheels also can be used on aluminum storm doors.
Put on rubber gloves and squirt two to three drops of dish detergent into a bucket of water. Swish with your gloved hand in the bucket to create suds.
Wash the aluminum door with a large sponge and the soapy water. Use a nylon brush on any hardened stains such as dead bugs. Do not use a steel wool pad on the aluminum because you may scratch the surface.
Rinse the storm door with clean water and the sponge. Make sure to remove all soap residue from the door.
Dry the aluminum storm door with clean, dry rags.
Apply an aluminum cleaner to the storm door. Spray or wipe the cleaner on with a clean soft cloth. Read the instructions on the aluminum cleaner on how much to use. The aluminum cleaner brings back the shine to the door's surface.
Wipe the aluminum storm doors weekly with a soft cloth to remove dust and grime that builds up and dulls the door's appearance.
