WD-40 is one of the most versatile and widely used products in the world, with a multitude of applications ranging from lubricating squeaky door hinges to protecting tools from rust. However, despite its versatility, there are certain surfaces and materials that you should never use WD-40 on. In this article, we will explore the various surfaces and materials that are not suitable for WD-40, and provide you with a comprehensive guide on how to use this product safely and effectively.
Introduction to WD-40
Before we dive into the details of what can’t you put WD-40 on, it’s essential to understand what WD-40 is and how it works. WD-40 is a penetrating oil that is designed to loosen stuck parts, protect metal from rust and corrosion, and displace moisture. It is a widely used product that has been around for decades, and its effectiveness and versatility have made it a staple in many households and industries.
Chemical Composition of WD-40
WD-40 is a complex mixture of various chemical compounds, including mineral oil, petroleum-based ingredients, and other additives. The exact chemical composition of WD-40 is a trade secret, but it is known to contain a combination of solvents, lubricants, and corrosion inhibitors. The chemical composition of WD-40 is what makes it so effective at penetrating and loosening stuck parts, but it also means that it can be harmful to certain surfaces and materials.
Surfaces and Materials to Avoid
While WD-40 is generally safe to use on most metal surfaces, there are certain surfaces and materials that you should avoid using it on. These include:
WD-40 can damage or discolor certain types of paint, varnish, and wood finishes, so it’s essential to test it on a small, inconspicuous area first.
It can also damage or corrode certain types of plastic, rubber, and silicone, so it’s crucial to avoid using it on these materials.
In addition, WD-40 can leave a residue on surfaces that can attract dirt and dust, which can be problematic for surfaces that require a high level of cleanliness, such as kitchen counters and medical equipment.
Painted Surfaces
One of the most critical things to avoid using WD-40 on is painted surfaces. WD-40 can damage or discolor certain types of paint, including latex-based paints, acrylic paints, and epoxy paints. If you need to lubricate a squeaky door hinge or protect a metal surface that is painted, it’s best to use a different product that is specifically designed for use on painted surfaces.
Electrical Components
Another surface that you should avoid using WD-40 on is electrical components. WD-40 can conduct electricity, which can cause electrical shocks or even start a fire. In addition, the chemical composition of WD-40 can damage or corrode certain electrical components, such as circuit boards and wires. If you need to lubricate or protect electrical components, it’s best to use a product that is specifically designed for use on electrical systems.
Corrosion Protection
While WD-40 is excellent at protecting metal from rust and corrosion, it’s not suitable for all types of metal. WD-40 can react with certain types of metal, such as aluminum and brass, to form a corrosive compound that can damage the metal. If you need to protect metal from rust and corrosion, it’s essential to choose a product that is specifically designed for use on the type of metal you are working with.

Can I use WD-40 on rubber or plastic parts?
Using WD-40 on rubber or plastic parts can be damaging and cause them to deteriorate over time. WD-40 is a solvent-based product that can break down or dissolve certain types of rubber and plastic, including natural rubber, silicone, and thermoplastics. This can cause the material to become brittle, crack, or break, leading to premature wear and failure. Additionally, WD-40 can leave a residue on surfaces, which can attract dust and dirt, causing further damage and deterioration.
To protect your rubber or plastic parts, it is essential to use alternative products specifically designed for these materials. For example, silicone-based sprays or conditioners can help lubricate and protect rubber parts, while plastic-safe cleaners can be used to clean and maintain plastic surfaces. When using any product on rubber or plastic parts, make sure to read the label and follow the manufacturer’s instructions. It is also crucial to test the product on a small, inconspicuous area first to ensure it does not cause damage or discoloration. By choosing the right product and following proper use guidelines, you can help extend the life of your rubber and plastic parts.
Is it safe to use WD-40 on skin or hair?
Using WD-40 on skin or hair is not safe and can be hazardous to your health. WD-40 is a petroleum-based product that can cause skin irritation, including redness, itching, and rashes. Additionally, WD-40 can be toxic if ingested or absorbed through the skin, and can cause serious health problems, including respiratory issues and organ damage. If you need to remove a stubborn stain or adhesive from skin or hair, it is essential to use a gentle, non-toxic product specifically designed for this purpose.
To protect your skin and hair, it is crucial to avoid using WD-40 or any other non-medical product on your body. If you accidentally get WD-40 on your skin or hair, wash the area immediately with soap and water, and seek medical attention if you experience any adverse reactions. For skin and hair care, use only gentle, non-toxic products that are specifically designed for human use. Remember, WD-40 is a industrial product intended for use on mechanical components, and its use on skin or hair can have serious health consequences. Always prioritize your health and safety, and choose products that are safe and gentle for use on your body.
Can I use WD-40 on natural stone or concrete surfaces?
Using WD-40 on natural stone or concrete surfaces is not recommended, as it can damage the material and cause discoloration. WD-40 is a solvent-based product that can break down or dissolve certain types of stone or concrete sealers, causing the material to become dull and discolored. Additionally, WD-40 can leave a residue on surfaces, which can attract dust and dirt, causing further damage and deterioration. If you need to clean or protect natural stone or concrete surfaces, it is essential to use a product specifically designed for this purpose.
