How to Clean Corroded Aluminum With Hydrochloric Acid
- 1). Put on thick work clothes with long sleeves and pants. Cover your hands with rubber gloves, and put on safety glasses and a filtration mask.
- 2). Place a non-reactive rubber tub outdoors, in a well-ventilated area.
- 3). Mix a solution of 20 parts water to 1 part hydrochloric acid. It's important to pour the water into the rubber tub first, and then slowly add the acid, being careful not to splash it. Mix the solution with a paint stirring stick.
- 4). Place the corroded aluminum into the solution. Allow it to set submerged for about 10 minutes. You'll see bubbles releasing from the corrosion as the acid removes it from the aluminum.
- 5). Remove the aluminum from the solution, and rinse it thoroughly with ample amounts of water from a garden hose. Let the aluminum air-dry completely before touching or using it.
- 6). Repeat this process with a solution of 10 parts water to 1 part acid, if the corrosion remains on the aluminum item.
