Is WD-40 Flammable After It Dries?

WD-40 is a popular household lubricant and cleaner known for its versatility in fixing squeaky hinges, loosening rusty bolts, and removing tough stains. However, there is often confusion regarding its flammability, especially after it has dried. In this article, we will explore whether WD-40 is flammable once it dries and the precautions one should take when using this product.

The Composition of WD-40

Before determining whether WD-40 is flammable after it dries, it’s essential to understand its composition. WD-40 primarily consists of mineral spirits, which are hydrocarbons made from petroleum distillation, along with a small percentage of other ingredients such as lubricating oils and various additives.

Flammability of WD-40

The flammability of WD-40 is primarily dependent on its composition, particularly the mineral spirits it contains. Mineral spirits are volatile and highly flammable substances that vaporize quickly when exposed to air. Therefore, WD-40 itself is considered flammable, both in its liquid and aerosol forms.

However, the key concern is whether WD-40 remains flammable once it has dried on a surface. When WD-40 dries, it leaves behind a thin protective film that acts as a barrier, reducing the potential for the vapors to ignite. Although this film is flammable, it forms a much thinner layer compared to the initial liquid application.

Precautions to Take

While WD-40 is generally safe to use, it is important to take certain precautions to prevent any potential accidents:

  • Avoid applying WD-40 near open flames or other potential ignition sources.
  • Ensure proper ventilation when using WD-40 in enclosed spaces to avoid the build-up of flammable vapors.
  • Store WD-40 in a cool, dry place and away from direct sunlight or heat sources.
  • Keep WD-40 out of reach of children and pets.
  • Follow the instructions and warnings provided on the product’s label.

  5. Removing gum from hair: WD-40 can assist in removing chewing gum from hair by making it easier to slide the gum off.

In Conclusion

WD-40 is flammable both in its liquid and aerosol forms, primarily due to the mineral spirits it contains. Although it is less flammable once dried, it still poses a fire hazard. When using WD-40, it is crucial to follow the instructions provided, take necessary precautions, and ensure proper ventilation to minimize any potential risks. Remember to store it safely and keep it away from children and pets. Despite its flammability, WD-40 remains a valuable tool for thousands of everyday tasks, making it an essential product to have in your household.
