Aluminum is a silvery white metal that is often used for its aesthetic purpose. For example, aluminum touches are frequently included in kitchens, and car rims are usually made of aluminum. Aluminum is also widely used because it is naturally resistant to corrosion. However, as with all metals, aluminum does tarnish and needs regular cleanings to look its best.
Before you can clean the rims, you must take the wheels off of your car unless you can remove the rims separately. Once the wheels or rims are off, remove grease and other sludge by rubbing salt directly onto the affected area. Use paper towels or a clean car rag to take off the grease. Add salt to a bucket of water, and use the salted water to clean off any excess grease or salt on the rim. Pat dry as necessary, and use other cleaning techniques as necessary to remove discoloration and restore shine.
Cream of Tartar
Traditionally used in baking, cream of tartar is used to clean aluminum surfaces. Combine 2 parts of cream of tartar with 1 part water, whisking until dissolved. Dip a clean, soft cloth or towel into the cream of tartar mixture, and wipe the aluminum surface with it. However, to restore the shine of aluminum and remove discoloration, combine lemon juice with cream of tartar and distilled white vinegar in equal parts. Dip a paper towel or soft wrap into the mixture, and rub it across the aluminum rims. Alternatively, put the mixture in a spray bottle, spray it onto the aluminum rims and use a paper towel or soft cloth to wipe the excess residue away.
Vinegar is also an all-purpose cleaner for aluminum. Pour vinegar on the aluminum rims, and use a sponge or clean towel in a circular motion to polish or clean the aluminum rim. Repeat as necessary.
