WD40, or Water Displacement 40th formula, is a popular lubricating and penetrating oil spray. It’s used to protect metal surfaces from rust, to lubricate moving parts, and to clean away dirt, dust, and grime. WD40 is known for its ability to get into hard-to-reach places and to penetrate deeply into surfaces to provide long-lasting lubrication and protection. But, one of the most common questions about WD40 is “how long does it take for WD40 to dry?”
The answer to this question depends on several factors, including the type of WD40 used, the surface it is being applied to, and the temperature and humidity of the area. In general, WD40 will dry in just a few minutes, but it can take up to an hour for it to completely evaporate.
There are two main types of WD40 – aerosol and liquid. Aerosol WD40 is pressurized and dispenses as a fine mist. It is designed to quickly penetrate and lubricate surfaces. Aerosol WD40 usually dries within minutes, though it can take up to an hour for it to completely evaporate.
Liquid WD40 is not pressurized and dispenses as a thick liquid. It is designed to deeply penetrate surfaces and provide long-lasting lubrication and protection. Liquid WD40 usually takes longer to dry, typically between 30-60 minutes, though it can take up to an hour for it to completely evaporate.
The surface WD40 is applied to can also affect how quickly it dries. On metal surfaces, WD40 will usually dry within a few minutes. On plastic or rubber surfaces, however, it can take longer for WD40 to dry completely. Additionally, WD40 will evaporate more quickly in warm, dry environments, and more slowly in cold, humid environments.
How to Speed Up the Drying Process
If you need to speed up the drying process, there are a few things you can do. First, make sure you shake the can or bottle of WD40 before each use. This will help to ensure that the liquid is evenly dispersed when it is applied.
After applying WD40, you can use a cloth or brush to spread it out and allow it to penetrate more quickly. You can also use a fan or hairdryer set to low heat to help evaporate the WD40 more quickly.
What to Do if WD40 Doesn’t Dry
If WD40 does not seem to be drying, the surface may be too cold or too damp. Try applying WD40 in a warmer, drier environment and allow it to sit for a few minutes before wiping away any excess. If the surface is still too cold or too damp, try using a fan or hairdryer set to low heat.
Tips for Applying WD40
WD40 is a useful tool for lubricating and protecting metal surfaces, but it can also be used to clean dirt and grime. To get the most out of WD40, here are a few tips:
- Shake the can or bottle of WD40 before each use to ensure that the liquid is evenly dispersed.
- Apply WD40 in a warm, dry environment for maximum effectiveness.
- Use a cloth or brush to spread WD40 and allow it to penetrate more quickly.
- Use a fan or hairdryer set to low heat to help evaporate WD40 more quickly.
- For stubborn dirt and grime, let WD40 sit for a few minutes before wiping away the excess.

Yes, WD40 can be used on plastic or rubber surfaces, but it may take longer for it to dry completely. Additionally, WD40 will evaporate more quickly in warm, dry environments, and more slowly in cold, humid environments.
Is WD40 flammable?
Yes, WD40 is flammable and should not be used near open flames or in areas with poor ventilation.
Can WD40 damage metal surfaces?
No, WD40 is designed to protect metal surfaces from rust and corrosion and has no damaging effects. However, it is important to take precautions when applying WD40 to metal surfaces, as it can be slippery when wet.
Does WD40 have a smell?
Yes, WD40 has a distinctive smell that some people find unpleasant. It is important to use WD40 in a well-ventilated area to avoid breathing in the fumes.
Can WD40 be used on painted surfaces?
Yes, WD40 can be used on painted surfaces, but it is important to take precautions to avoid damaging the paint. Before using WD40, make sure to test it on an inconspicuous area of the surface to make sure it does not cause any damage.
Does WD40 leave a residue?
No, WD40 does not leave a residue when used properly. However, if WD40 is not completely evaporated, it can leave a greasy residue on the surface.
Can WD40 be used on electrical components?
Yes, WD40 can be used on electrical components, but it is important to take precautions to avoid short-circuiting the components. Make sure to unplug the device before applying WD40, and allow the WD40 to completely evaporate before plugging the device back in.
