### Is WD40 Safe for Electrical Contacts? Understanding the Risks and Benefits
WD40 is often touted as a cure-all for various household and automotive issues. However, when it comes to electrical contacts, its suitability is a complex question. To fully understand the implications of using *wd40 on electrical contacts*, we need to examine its composition, intended use, and potential effects on electrical components.
#### What is WD40 and What is it Intended For?
WD40 is a multi-purpose product designed primarily as a water displacement and rust preventative. Its name stands for “Water Displacement, 40th formula.” Originally developed in 1953 by the Rocket Chemical Company, WD40 was intended to protect missile parts from corrosion by displacing water. Over time, it found widespread use as a lubricant, cleaner, and protectant for various applications.
#### The Composition of WD40: A Closer Look
WD40’s exact formulation is a trade secret, but its Material Safety Data Sheet (MSDS) reveals its key components: aliphatic hydrocarbons (mineral spirits), petroleum base oil, and carbon dioxide propellant. These ingredients contribute to its lubricating, penetrating, and water-displacing properties. However, it’s important to note that WD40 is *not* a dedicated electrical contact cleaner.
#### Potential Benefits of Using WD40 on Electrical Contacts
* **Water Displacement:** WD40 excels at displacing moisture, which can prevent corrosion and improve conductivity in wet environments.
* **Cleaning:** It can help dissolve light dirt, dust, and grime, potentially improving contact between electrical surfaces.
* **Lubrication:** WD40 can reduce friction in moving electrical components, such as switches and relays.
#### Significant Risks and Drawbacks of Using WD40 on Electrical Contacts
* **Residue Buildup:** WD40 leaves behind a residue that can attract dust and dirt, potentially leading to future conductivity problems.
* **Flammability:** WD40 is flammable, posing a fire hazard if used near sparks or high temperatures.
* **Material Compatibility:** It can degrade certain plastics and rubbers commonly used in electrical components, leading to premature failure.
* **Not a True Cleaner:** While it can dissolve some grime, it’s not specifically formulated to remove oxidation or other contaminants that cause electrical issues.
* **Short-Term Fix:** The lubrication provided is temporary and can lead to more problems down the road as the lubricant dries and collects debris.
