Does WD40 Conduct Electricity? [What You Need to Know]

Have you ever encountered electrical issues that you thought could be solved with WD40? Have you ever wondered if WD40 could be a good conductor of electricity?

Does WD40 conduct electricity? The answer is no. WD-40 is not a conductor of electricity but an insulator with a low dielectric strength of 35KV. It is designed to be a good insulator, leaving a thin film on electrical components that do not interfere with the electrical connection. For delicate electrical components, use the non-conductive “WD-40 Specialist Contact Cleaner,” which is designed specifically for this purpose.

Let’s dig into more detail.

No, WD-40 does not conduct electricity. It is an insulator with a low dielectric strength of 35KV. 

When it dries out, it leaves a fragile film on your electrical components that does not interfere with the electrical connection. It can drive moisture from electric elements, save flooded equipment, and restore electrical connections.

For more delicate electrical components, you should use the non-conductive “WD-40 Specialist Contact Cleaner,” which is designed specifically for this purpose. 

Unlike some contact cleaners on the market, it leaves no residue or deposits, which could accumulate and potentially lead to issues like a short circuit. 

The fast-acting, non-conductive, and non-corrosive WD-40 Specialist Contact Cleaner is suited for use on all delicate surfaces and electrical components. 

It offers excellent cleaning results with little effort and effortlessly eliminates dirt, dust, moisture, and flux residue without endangering delicate electrical or electronic components.

Whenever you use WD-40, always remember to turn off your electrical device before using it and let it dry entirely before powering it up. 

Don’t rely on WD-40 for conducting electricity, but do use it for cleaning electrical components and restoring electrical connections. WD-40 is a great product to have in your toolbox, but make sure you are using the right product for the right job.

Can You Spray WD40 on Electrical Connections?

Yes, you can spray WD-40 on electrical connections. It is an excellent choice for cleaning and lubricating the contacts in order to ensure that they are working properly without any hindrance or shorting out of the power supply.

WD-40 acts as a solvent that helps break down dirt build up, rust particles, and other contaminants from the surface while also providing superior protection against corrosion caused due to humidity & moisture present in the air. 

The unique nonconductive formula ensures safety during use near sensitive electronic parts making it ideal for application even with delicate equipment like computers where static electricity could be generated by improper handling, causing possible damage to them over time.

Moreover, since no residue remains after usage, unlike many other aerosol sprays available today, this makes using WD40 a much more convenient option when dealing with electronics maintenance-related tasks.

Does WD-40 Damage Electronics?


In short, the answer to this question is both yes and no. WD-40 can be used on some electronics safely as it does not conduct electricity and will not damage them. However, there are a few risks that you should consider before using it. 

It’s flammable which could potentially cause sparks or fires if applied in an area with high voltage levels or if left inside of devices generating excessive heat, such as phones or computers.

When dealing with sensitive electronics like circuit boards, one must exercise caution when applying any lubricant due to potential corrosion problems caused by spraying. 

To minimize these effects, make sure your device isn’t plugged in while cleaning areas where metal contacts meet, also use lint-free cloths dampened lightly with rubbing alcohol instead of sprays containing solvents.

Finally safety-wise, always wear protective gear such as gloves made out of rubber material since oils found in products similar may contain hazardous chemicals causing skin irritation and burns.

Does WD40 Cause Short Circuits in Electronics?

Yes, WD-40 can cause a short circuit. This is because it contains an aerosol, which makes the oil highly flammable and combustible when dry. 

When applied to electronics or gadgets that create sparks due to the electrical current running through them, this could potentially lead to a short circuit if not handled with caution. 

As an example: If you were using WD-40 on wires connected directly to your wall outlet, then there’s always potential for arcing from one wire leading back towards another, creating a spark. This causes ignition of WD-40 resulting in smoke and heat buildup–which might result in melting insulation around cables leading ultimately up towards a short circuit.

As such, it’s best practice NOT TO use any form of petroleum-based products near anything related to electrically powered equipment unless instructed by the manufacturer/professional.

Even “accidental contact” between two metal surfaces while applying said product has been known before triggering off unintended events, so be extra careful whenever working close by these sorts of appliances! 

Lastly, make sure everything gets wiped down afterward, just in case residual moisture left behind inadvertently causes corrosion over time.

Final Words

So, does WD40 conduct electricity? No, it doesn’t conduct electricity and can be sprayed on electrical connections with caution. It’s possible for WD40 to damage electronics and cause short circuits since it is flammable, so you must practice caution.
