How to Clean Oxidized Aluminum Engine Parts? | How to Clean Aluminum Engine Corrosion?

Aluminum is more favorable than other metals because of its excellent characteristics such as excellent machinability, lightweight, corrosion resistance, high thermal conductivity, low density, and useful strength. Therefore, aluminum is most commonly used to make different parts of the car engine. Before starting the discussion about how to clean oxidized aluminum engine parts, you must first understand what aluminum (AI) is and why you need to clean it.

Aluminum is most commonly used to make automobile parts. The first aluminum engine was designed by Carl Benz in 1901. Such types of engines ware too much expansive. Therefore, after 60 years, the company closed the production of aluminum engines.  

Every 1kg of aluminum used in the construction of a car engine reduces the weight of the car by 1kg. Therefore, nowadays, aluminum is used for the construction of transmission block transmission bodies, radiators, engine blocks, intake manifold, and some other parts.

During the service life of aluminum, the aluminum surface undergoes some changes. These changes occur due to different reasons. Here we are going to discuss the reasons of the changes that could occur and also discuss how to clean aluminum engine parts. You will also learn how to preserve the original condition and make cast aluminum look as new.

How to clean oxidized aluminum engine parts?         

The removal of the oxidation from aluminum engine parts is not a tough task. Follow the below-given steps to remove the oxidization from aluminum:

Step 1) Cleaning of Aluminum Surface

To remove the oxidization from the aluminum engine parts, you first need to clean the surface of the aluminum parts by washing them with boiling water for a couple of minutes. You can also wash them by using a strong high-pressure jet of water.

To clean the oxidized aluminum wheels and siding, wipe them with a damp cloth and clean them with a water hose. During the cleaning process, wash all the parts thoroughly with water and soap.

As the solution is boiled, your natural cleaner will be ready. Now immerse your part in it and let it sit for a few minutes.

When cleaning the large aluminum surface, dip a clean cloth in the boiling mixture. Use this dipped piece of cloth to clean the surface until it is no longer rusty. Finally, wipe off any vinegar residue with a dry cloth.

Step 3) Using the Oxidation Removal Product

If you have tried all of the above methods and still have not got your desired results, then use this last option. In this option, you need to use an antioxidant product. Oxidizing products contain chemicals that react with oxidation.
