When it comes to cleaning electrical connections, people often reach for the trusty can of WD40. It’s a common household item, and it’s known for its ability to penetrate and displace moisture, making it seem like a great solution for cleaning electrical connections. But can you really use WD40 to clean electrical connections? In this article, we’ll dive into the truth behind this common practice and explore the potential risks and benefits of using WD40 on electrical connections.
The Origins of WD40
Before we dive into whether or not you can use WD40 to clean electrical connections, let’s take a step back and look at the origins of this popular product. WD40 was first developed in the 1950s by the Rocket Chemical Company in San Diego, California. The company was working on a waterproofing solution for the Atlas missile, and they created a concoction of chemicals that would later become WD40.
The original formula for WD40 was designed to be a waterproofing agent, not a cleaning solution. It was meant to protect metal surfaces from rust and corrosion, not to clean electrical connections. Despite this, WD40 quickly became a popular household item, and people began using it for a variety of tasks, including cleaning electrical connections.
The Composition of WD40
So, what’s in WD40 that makes it seemingly effective at cleaning electrical connections? WD40 is a proprietary formula, but the main ingredients are:
- Mineral oil: This is the primary component of WD40, making up around 50% of the formula. Mineral oil is a refined petroleum-based oil that’s used as a lubricant and a rust inhibitor.
- Aliphatic hydrocarbons: These are a type of hydrocarbon that’s used as a solvent and a cleaning agent. They’re responsible for the penetrating power of WD40, allowing it to seep into tight spaces and lift away dirt and grime.
- Carbon dioxide: This is added to the formula as a propellant, allowing WD40 to spray out of the can in a fine mist.
- Other additives: WD40 also contains a range of other additives, including detergents, corrosion inhibitors, and fragrances.
Potential Risks of Using WD40 on Electrical Connections
While WD40 may seem like a quick fix for cleaning electrical connections, there are some potential risks to consider:
Moisture Attraction
One of the biggest risks of using WD40 on electrical connections is that it can attract moisture. The mineral oil in WD40 can leave behind a residue that’s hygroscopic, meaning it attracts and retains water molecules. This can lead to corrosion and electrical failures over time.
Insulation Breakdown
WD40 is a solvent-based cleaner, which means it can break down the insulation on electrical wires. This can lead to electrical shorts and failures, which can be dangerous and even catastrophic.
Incompatibility with Plastics
WD40 can damage certain types of plastics, including those used in electrical connectors and insulators. This can lead to cracking, brittleness, and ultimately, electrical failures.
Alternatives to WD40 for Cleaning Electrical Connections
So, what’s a better option for cleaning electrical connections? Here are a few alternatives to WD40:
Deionized Water and a Soft Brush
A gentle approach is often the best way to clean electrical connections. Use deionized water and a soft-bristled brush to remove dirt and debris from the connection points. This method is safe, effective, and won’t damage the electrical components.
Compressed Air
Compressed air is a great way to blow away dirt and debris from electrical connections. Just be sure to use a gentle touch and avoid spraying the air directly onto the components.
Specially Designed Cleaning Solutions
There are a range of cleaning solutions on the market that are specifically designed for cleaning electrical connections. These solutions are usually formulated to be safe on electrical components and won’t leave behind any residues or attract moisture.
When to Use WD40 on Electrical Connections
While WD40 isn’t the best choice for cleaning electrical connections, there are some scenarios where it might be useful:
Rusted or Corroded Connections
If you’re dealing with severely rusted or corroded electrical connections, WD40 might be useful for penetrating the corrosion and loosening the rust. However, be sure to wipe away any excess WD40 and dry the area thoroughly to prevent moisture attraction.
Old or Neglected Connections
If you’re working with old or neglected electrical connections, WD40 might be useful for cleaning away dirt and grime. Just be sure to use a gentle touch and avoid spraying WD40 directly onto the components.
Conclusion
In conclusion, while WD40 might seem like a convenient solution for cleaning electrical connections, it’s not the best choice. The risks associated with using WD40 on electrical connections, including moisture attraction, insulation breakdown, and incompatibility with plastics, outweigh any potential benefits.
Instead, opt for gentle cleaning methods, such as using deionized water and a soft-bristled brush, compressed air, or specially designed cleaning solutions. These methods are safer, more effective, and won’t put your electrical components at risk.
Remember, when it comes to electrical connections, it’s always better to err on the side of caution. Take the time to choose the right cleaning method, and you’ll be rewarded with safe, reliable, and efficient electrical connections.
