WD40 is a popular aerosol for safeguarding metals against dust and corrosion. It acts as a solvent to dissolve sticky components. In this article, we will take you through certain details about WD40, whether it’s flammable and its effects on some items.
What’s More On WD40?
WD40 is a product of a chemical company that deals with the manufacturing of consumer goods. The WD40 company produces goods of sound quality at an affordable price.
This famous spray came into the limelight in the 1960s. And it became a standard industrial product in 1965. WD40 was originally produced to prevent the outer layer of the Atlas missile from corroding.
However, in 1958, WD40 was introduced as a consumer product because of its multipurpose quality. That said, the primary aim of WD40 sprayers is to act as a solvent medium. WD40 lubricates materials and eliminates dampness.
When sprayed on material, this multipurpose aerosol removes oil and filth. Specifically, WD40 aerosol is generated from pressurized gas.
Now, the big question comes in. Is WD40 flammable? Let’s discover.
Is WD40 Flammable? How Flammable is Wd40?
Yes, this WD40 is volatile and flammable. Typically, the components of WD40 are not flammable. However, the sprayer itself is flammable.
WD40 usually becomes more flammable when it is sprayed or propelled by butane. This is because its surface-to-volume ratio shifts when it’s in the gaseous form. Such that when you spray WD40 near a naked flame or sparks, it will attract fire instantly.
Because of the flame’s high heat, the aerosol container can explode and burst. So it is not advisable to spray WD40 in a poorly ventilated room and bare fire.
Is Dry WD40 Flammable?
Just like its moist form, dry WD40 is also flammable. This is primarily because all WD40 (either dry or solvent) are petrochemical products.
However, there’s a slight difference between the flammability nature of the two forms of WD40. While most WD40 can start a fire, its dry form will only ignite slowly and faintly.
Is WD40 Explosive?
Yes, WD40 is explosive when sprinkled close to a naked fire or any combustible material. The flash point temperature of liquid WD40 is 47°C. Its explosive limit ranges between 0.6% to 8.2% volume.
WD40 combines with air to form a volatile mixture. Thus, when the WD40 explosive limit is above 0.6% or less than 8.2% in air, the aerosol will ignite, triggering an explosion.
Is WD40 Toxic?
When WD40 burns, breathing in its smoke can be harmful. Especially when you are exposed to the smoke for a long time. This is because moisture and vapor usually irritate the lung and throat.
So WD40 can trigger irritations in the respiratory and olfactory systems. It can also cause vomiting, dizziness, and many more undesirable health conditions.
Over-exposure to WD40 can also cause cancerous growth. WD40 contains benzene—a dangerous toxin that induces cancer. Moreso, WD-40 can cause leukaemia.

Does WD40 Evaporate Spontaneously?
When you spray WD40 aerosol, about 20% of its contents will evaporate. However, they don’t evaporate in the proper sense. They only allow the sprayer to disperse.
Is WD40 Dangerous To Plants?
Absolutely yes! WD-40 is harmful to plants. Don’t spray it on your vegetation or even bring it near them.
Is WD40 Harmful To Fish?
You can spray WD-40 to prevent fishing equipment from rusting. However, this does not mean that it is okay for fish to come in contact with it. Fishes can show some side effects if exposed to WD-40 for a long time.
Effect Of WD-40 On The Skin
WD-40 is not that harmful to your skin. However, prolonged exposure to this volatile aerosol can cause skin irritations, such as skin burns, redness, itching, and dermatitis.
Effects Of WD40 On Plastic.
WD-40 is safe to use on any kind of material. Be it plastic, metal, rubber, or even wood, you’re ready with a WD-40 spray. But there’s one aspect to note when applying WD40 on plastics.
There are several kinds of plastics and you’re free to spray WD-40 on all but two. These two plastics are polystyrene and polycarbonate.
You can find polystyrene in the lids of soft drinks, styrofoam, etc. Polycarbonate plastics are used in greenhouses. Just like clear polystyrene, polycarbonate is transparent plastic.

Items You Should Not Spray With WD40
WD-40 aerosol is a partial lubricant. This spray performs an excellent job on most materials because it readily removes oil from a surface.
However, one peculiar fact about this spray is that it doesn’t work on all materials. There are exceptions to its application.
Below is a list of items you should never spray with WD-40. Let’s look at them.
Spraying WD40 on your day-to-day electronic equipment is not a good idea. Especially if there are some scraps of plastic in these appliances, e.g., Electric Iron. WD-40 will readily dissolve the plastics in electronic equipment, rendering it useless for you.
WD-40 traps specks of dust and other dirt on a door hinge.
If you spray WD40 frequently on your locks, it can trigger the locking system to reduce in value.
WD-40 accumulates filths in the chains of bicycles. This can clog up the chains and cause unforeseen accidents.
Why Is WD40 Not Accepted In California?
Volatile organic compounds (VOCs) are usually used as an ingredient in most aerosols. However, volatile organic compounds are toxic to human health.
Meanwhile, one of the major ingredients in WD-40 is VOCs. Because of this, the California government does not support the use of WD-40 multipurpose products in the country. Such that anyone who uses a WD40 sprayer in California is considered to be using an illegal product.
