About Cleaning Aluminum

Aluminum is the one of the most abundant elements found in the Earth's crust, ranking third behind oxygen and silicon, although because of its tendency to bind with other elements it is only found in a combination state. Because aluminum is both light and strong, and is readily recyclable, it is used in a remarkable array of commercial and consumer applications. How you clean this versatile metal depends upon how it is being used.

History

Aluminum derives its name from the Latin, alumen. The ium ending was added to make alumenium conform to the sound of most other elements. The United States, however, uses the spelling determined by the American Chemical Society in 1925 -- aluminum. Hans Christian Oersted is credited with first producing aluminum metal in 1825, but Frederick Wohler built on Oersted's process and eventually determined aluminum's specific gravity. Aluminum was used by the Wright brothers in their first airplane and has become a prime factor in the establishment of the aircraft industry.

Identification

Aluminum has an attractive silvery sheen which is quite resistant to corrosion. Because aluminum bonds rapidly with oxygen, the bare metal will quickly form a gray oxidized coating that protects the underlying metal from further corrosion. This oxidation may be rubbed or polished off but the oxidation process will only reoccur. Most exposed aluminum surfaces including appliances, cookware and utensils are lacquered, painted or anodized to prevent the continuation of the oxidation process.

Features

Proper cleaning of aluminum products depends in large part on what the aluminum is used for. Aluminum cookware and utensils can be cleaned by a solution of household vinegar and cream of tartar. The outside of aluminum cookware may be cleaned with silver polish according to the manufacturer's instructions or with a non-abrasive cleanser. Abrasive cleansers and steel wool pads are not recommended as these products can mar the surface of aluminum cookware.

Outdoor Use

Aluminum that is designed for outdoor use is frequently lacquered, painted or polished and can stand up to tough cleaning processes. It is important to remove foreign contaminants such as bugs and tree sap as soon as possible. The longer they are allowed to bake in the sun, the harder they will be to remove. Hose down the surface and apply your favorite de-greasing cleanser to the surface with a sponge or cleaning rag. For tough deposits use a stiff nylon bristle brush. Do not use steel wool or abrasive cleansers. Rinse with clear water and wipe with a dry towel or allow to air dry.

Considerations

Never use scouring powder, sharp scrapers or abrasives on aluminum cookware or utensils. Avoid baking soda as it may discolor aluminum. Always allow aluminum cookware to cool completely prior to cleaning. If food becomes burnt on, remove as much of the residue as possible with a wooden or plastic spatula. Allow the pan to soak in hot water and detergent to loosen remaining food or grease. Clean with a soap-filled sponge or cleaning cloth.
