Aluminum is a metallic element that is derived from the chemical group of boron. Because it is one of the most ample elements in the earth's crust, aluminum is readily available and used in a wide range of products. Aluminum alloys (pure aluminum mixed with other metals) are used in everything from cooking utensils to household furnishings and vehicles. Aluminum is resistant to breakdown because it forms a strong chemical bond with oxygen. This is why aluminum often becomes discolored or dull in appearance. To clean aluminum, acid needs to be used in order to neutralize the buildup of oxidation. Follow these steps for using acid wash on aluminum products.
Method 1 of 2: Acid Wash Small Aluminum Items
1Remove dust and dirt from smaller items, such as pots, pans, utensils or decorations. Soak your aluminum item in a sink filled with hot water. Gently scrub the items with mild dish liquid, rinse and dry thoroughly.Ad
2Prepare the acid wash. Fill a pot with 4 cups (.95 liters) of water and 2 tbsp. (30 ml) of lemon juice or vinegar.
3Bring the acid solution to a boil. Allow the solution to remain at a high boil for 15 minutes. While the solution is boiling, place all aluminum items in the pot.
4Drain the solution. Carefully remove the pot of boiling solution from the heat and drain it, along with the items, into the sink.
5Rinse the items thoroughly with warm water.
6Check the aluminum items, and repeat the process if the stains aren't removed.
Method 2 of 2: Acid Wash Large Aluminum Items
1Purchase a commercial acid wash. Also called aluminum brightener, acid wash is available at home improvement stores and is ideal for washing larger aluminum items, such as car wheels or boats.
2Put on gloves and protective eyewear. When working with commercial acid, always cover your skin to avoid contact with the solution.
3Mix the acid wash or aluminum brightener with water according to the manufacturer's instructions. It's often recommended to start out with a 1 to 10 ratio of wash to water, and then strengthen if necessary.
4Wash with the acid wash. Dip a scratch-resistant scrub pad or brush into the solution. Apply to the affected aluminum and scrub in circles until the oxidized stain comes off and the aluminum is shiny.
5Rinse the acid wash. Rinse all aluminum thoroughly with clean water and dry with a clean, soft cloth.Ad
