My Secrets To Making Aluminum Engine Parts Looks New (Remove Oxidation)

Aluminum parts are widely used in automotive. It all started in 1901 when Carl Benz built the first aluminum engine. Due to the high price of aluminum, the company stopped using it right after 60 years. In 1961 a full V8 engine made by Land Rover’s mass-produced Buick 215 was made with aluminum.

Every kilogram of aluminum used in the car reduced the overall weight of the vehicle by one kilogram. As a result, we now have more car parts, such as intake manifolds, engine blocks, radiators, transmission bodies, and other body parts made with aluminum.

Aluminum is more preferred due to its special properties like useful strength, low density, high thermal conductivity, resistance to corrosion lightweight, and outstanding machining behavior. However, what happens to these parts after a while of usage and exposure to the atmospheric factors?

Several changes happen to the surface of aluminum during its lifetime. We will be going through the changes, why they happen, and how to clean aluminum engine parts. We shall also learn how to maintain its original state and how to make cast aluminum look new. This video will also direct you to clean engine parts.

First, before we learn how to clean aluminum engine parts, we should know what aluminum is and why we should clean it. Aluminum is a metallic element. It has been used since ancient times in Egypt and Rome. Aluminum easily bends to make a strong and lightweight alloy, which is a good conductor of heat and electricity.

These great properties make it ideal for many uses in the automotive industry. Therefore, when rebuilding or selling your vehicle or any other reason, it is crucial to clean the aluminum parts in your vehicle. In the past, people only cleaned cast iron and steel components.

Up to date, aluminum is mainly used in the engine construction of vehicles and other automobiles. This guide will also help you in cleaning aluminum motorcycle engine cases with ease. It is crucial to understand that different metals have different handling and cleaning methods.

The change of the building materials and increased usage of aluminum in engine parts brought a necessity to know its cleaning methods. Equipment used to clean other metals in the past are not ideal for cleaning aluminum components. There are special aluminum cleaning chemicals.

There are several products used to clean cast iron that cannot be used on aluminum since it may cause damage. Safety should always come first. Prepare the safety gear that will keep you safe during the process. You may use chemicals such as aluminum cleaner or high concentration oxidation removal, which are harmful to your health.

The safety gear should contain good eye protection glasses, a protective dress, and a face mask. You also need to work in a well-ventilated and away from children. Also, be careful not to touch any flames with the items used in the cleaning process.
