WD-40 is one of the most versatile and widely used products in the world, with a multitude of applications that range from lubricating squeaky door hinges to protecting tools from rust. However, despite its many uses, there are certain situations where using WD-40 can do more harm than good. In this article, we’ll explore the surprising times when you shouldn’t use WD-40, and what alternatives you can use instead.
What is WD-40?
Before we dive into the situations where you shouldn’t use WD-40, let’s take a brief look at what it 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 was first developed in the 1950s by the Norm Larsen Company, and its name comes from the phrase “water displacement, 40th attempt,” which refers to the fact that it took the company 40 attempts to develop a formula that could successfully displace water from metal surfaces.
How Does WD-40 Work?
WD-40 works by using a combination of solvents and oils to loosen stuck parts and protect metal from rust and corrosion. When you spray WD-40 onto a surface, the solvents in the formula quickly evaporate, leaving behind a thin layer of oil that helps to lubricate and protect the metal. This makes it an ideal solution for a wide range of applications, from lubricating squeaky door hinges to protecting tools from rust.
Situations Where You Shouldn’t Use WD-40
While WD-40 is an incredibly versatile product, there are certain situations where using it can do more harm than good. Here are some of the most surprising times when you shouldn’t use WD-40:
Painted Surfaces
One of the most important things to remember when using WD-40 is to avoid spraying it onto painted surfaces. The solvents in WD-40 can damage the paint and cause it to peel or flake off, which can be difficult and expensive to repair. If you need to lubricate a hinge or other moving part on a painted surface, it’s better to use a silicone-based lubricant instead.
Why Silicone-Based Lubricants are a Better Choice
Silicone-based lubricants are a better choice for painted surfaces because they are non-abrasive and won’t damage the paint. They are also waterproof, which makes them ideal for use in outdoor applications. Some popular silicone-based lubricants include Sil-Glyde and Dow Corning 111.
Electrical Components
Another situation where you shouldn’t use WD-40 is on electrical components. The oil in WD-40 can conduct electricity, which can cause short circuits and damage to electrical components. If you need to lubricate an electrical component, it’s better to use a lubricant that is specifically designed for use on electrical components, such as a silicone-based lubricant or a lubricant that is labeled as “electrically safe.”
Why Electrical Safety is Important
Electrical safety is important because it can help to prevent injuries and fatalities. According to the National Fire Protection Association (NFPA), electrical fires account for an estimated 51,000 home fires each year in the United States, resulting in 500 deaths and 1,400 injuries. By using a lubricant that is specifically designed for use on electrical components, you can help to reduce the risk of electrical fires and keep yourself and others safe.
Plastic and Rubber Components
WD-40 can also damage plastic and rubber components, which can cause them to become brittle and crack. If you need to lubricate a plastic or rubber component, it’s better to use a lubricant that is specifically designed for use on these types of materials, such as a silicone-based lubricant or a lubricant that is labeled as “safe for use on plastics and rubbers.”
Why Plastic and Rubber Components are Sensitive
Plastic and rubber components are sensitive because they can be damaged by the solvents in WD-40. The solvents in WD-40 can cause the plastic or rubber to become brittle and crack, which can lead to premature wear and tear. By using a lubricant that is specifically designed for use on these types of materials, you can help to extend the life of the component and prevent damage.
Food Preparation Surfaces
WD-40 should never be used on food preparation surfaces, as it can contaminate food and cause health problems. If you need to lubricate a hinge or other moving part on a food preparation surface, it’s better to use a lubricant that is specifically designed for use on food preparation surfaces, such as a food-grade lubricant.
Why Food Safety is Important
Food safety is important because it can help to prevent foodborne illnesses. According to the Centers for Disease Control and Prevention (CDC), foodborne illnesses affect an estimated 48 million people in the United States each year, resulting in 128,000 hospitalizations and 3,000 deaths. By using a lubricant that is specifically designed for use on food preparation surfaces, you can help to reduce the risk of foodborne illnesses and keep yourself and others safe.
Alternatives to WD-40
If you’re looking for alternatives to WD-40, there are several options available. Here are a few:
- Silicone-based lubricants: These lubricants are non-abrasive and won’t damage painted surfaces or electrical components. They are also waterproof, which makes them ideal for use in outdoor applications.
- White lithium grease: This lubricant is thick and gooey, which makes it ideal for use on hinges and other moving parts. It’s also waterproof, which makes it ideal for use in outdoor applications.
How to Choose the Right Alternative
Choosing the right alternative to WD-40 depends on the specific application. If you’re looking for a lubricant that is safe for use on painted surfaces, a silicone-based lubricant may be the best choice. If you’re looking for a lubricant that is thick and gooey, white lithium grease may be the best choice.
What to Consider When Choosing an Alternative
When choosing an alternative to WD-40, there are several things to consider. Here are a few:
| Consideration | Description |
|---|---|
| Surface type | What type of surface will the lubricant be used on? If it’s a painted surface, a silicone-based lubricant may be the best choice. |
| Application | What is the lubricant being used for? If it’s for a hinge or other moving part, a thick and gooey lubricant like white lithium grease may be the best choice. |
| Environmental conditions | Will the lubricant be exposed to water or extreme temperatures? If so, a waterproof lubricant like silicone-based lubricant or white lithium grease may be the best choice. |
