Aluminum is a light-weight metal with a bright silvery luster. Small amounts of other metals are added to aluminum to make harder alloys for most uses. Its affinity for oxygen makes it resistant to corrosion and attack by most chemicals. Most aluminum used in visible parts of appliances is lacquered or otherwise coated, anodized or painted.

Alkaline foods or water and some dishwasher detergents may leave a dark film on the surface of aluminum pans. This is harmless but not pleasing to the eye. Salty foods allowed to stand in pans may pit the metal. Pitted pans are safe to cook in, but hard to clean.

If painted, use a solution of mild detergent and water, or a mild commercial cleaner whose label says it is safe for painted surfaces. Always rinse off solution. Wipe off excess water with a dry cloth. Do not use strong cleaners or scouring powder as these will damage the paint. If you plan to clean window frames, do it before cleaning window glass so solution does not spot glass panes.

Aluminum does not rust, but it will discolor and develop a pitted or rough surface. Aluminum is affected by air pollutants. The surface will appear to have fine grit stuck to the surface, but it will not wipe away easily. If you observe aluminum storm windows and screens which have been exposed to weather for a couple years you will see what happens to aluminum outdoor furniture; the surface has oxidized.

Use mild a detergent and warm water when possible. Alkalis, even baking soda, and especially stronger alkalis discolor aluminum. If trying a stronger cleaner, pre-test on a hidden place to be sure it cleans satisfactorily and does not damage the aluminum. Always follow directions on the product label for aluminum, EXACTLY.
