WD-40 is a widely used multi-purpose spray that has various applications in both households and industries. It is well-known for its lubricating, cleaning, and rust-preventing properties. However, there has been considerable confusion and debate regarding whether WD-40 is flammable when it dries. In this article, we will dive into the topic and provide a clear answer to this commonly asked question.
The Composition of WD-40:
WD-40 is a unique formula composed of various ingredients, including petroleum-based mineral oil, aliphatic hydrocarbons, and additives. The combination of these components gives WD-40 its versatile properties. However, the flammability of WD-40 primarily depends on the volatile nature of some of its components.
Flammability of WD-40:
WD-40 does contain flammable materials, making it potentially hazardous in certain situations. The vapors from WD-40 can ignite and lead to a fire if exposed to an open flame, spark, or heat source above its flashpoint. The flashpoint for WD-40 is approximately 143 degrees Celsius (289 degrees Fahrenheit). This means that if the temperature exceeds this point, the substance can release enough vapor to ignite when exposed to an ignition source.
However, it is crucial to note that once WD-40 has dried on a surface, the risk of it catching fire decreases significantly. When the volatile solvents in WD-40 evaporate, the remaining residue acts as a protective layer, reducing the chance of the dried substance igniting. It is important, though, to exercise caution and avoid testing the flammability of WD-40 intentionally.

Precautions and Best Practices:
To ensure safety while using WD-40, it is essential to follow some precautions and best practices:
- Keep WD-40 away from open flames, sparks, or any heat sources.
- Store WD-40 in a cool, well-ventilated area away from direct sunlight.
- Avoid using WD-40 near flammable materials or in confined spaces.
- Read and follow the instructions provided on the product label.
- Keep WD-40 out of reach of children and pets.
- In case of accidental ignition or fire, use an appropriate fire extinguisher to put it out.

Final Thoughts:
In conclusion, WD-40 is flammable when in its liquid form due to its volatile components. However, once it has dried on a surface, the risk of flammability decreases significantly. It is essential to handle WD-40 with care, keeping it away from open flames, sparks, and heat sources. By following precautions and best practices, you can safely utilize WD-40 for its multiple purposes. Remember to always read and follow the instructions provided by the manufacturer for a safe experience.
