How Does Oiling Prevent Rusting?

Last Updated on

Rust is considered as one of the greatest enemies of iron and metals. It can easily destroy your car or any metal object in your home, which is why it shouldn’t be taken lightly.

The term “rust” is commonly used to describe the corrosion and oxidation of metals. You may ask; how does oiling prevent rusting?

You see, several traditional and modern techniques have been developed to prevent rust formation in metals. For example, VCI technology, oiling, and paint coating are the most popular techniques which metal-driven industries usually leverage.

Out of these three methods of preventing rust, oiling is the best. The reason is not far-fetched. Oil does not mix with water; instead, it forms a robust protective coating when applied on metals.

Plus, oil can penetrate and stabilize the oxide-water usually found on metal. What’s more? Oil can penetrate the nooks, holes, and restricted areas of metals to prevent corrosion.

In this post, you’ll get to know how oiling prevents rust on metals. But before we dive deeper, it is crucial to understand the rusting process.

Understanding the Rusting Process

How Does Oiling Prevent Rusting

In case you don’t know what rust means, the term rust is used to describe the chemical reaction involving metals, oxygen, and water. The result of the chemical reaction is known in science as a hydrated metal oxide.

In appearance, rust is a reddish-brown coat you see on metals or iron. Rust can affect everything from knives and bicycles to tanker ships and jumbo jets. Rust is triggered by moisture in the air.

Now, back to the question, “how does oiling prevent rusting?” You would agree with us that water is the primary cause of rust. This means, preventing water from getting to metals will prevent rust formation.

Since water and oil do not mix, it is common sense to apply oil if you want to prevent iron or metal from rusting. Scientific evidence shows that oil is less dense than water; thus, the oil will always float when added to water.

Water molecules are more attracted to each other than oil. This explains why water and oil cannot mix.

Research shows that when oil is applied on a metallic surface, it forms a protective layer which blocks any external elements from seeping through, including water.  Oil has repellant properties strong enough to repel the water that’s present in oxygen.


Like we mentioned earlier, rust is one of the greatest enemies of metals. Applying oil on the surface of any metal will prevent the metal from rust. The oil will thus form a protective layer and prevent water molecules from coming close to the metal.
