WD-40 is a water displacement spray that is commonly used to prevent rust and corrosion. While it is safe to use on electrical contacts and connections, opinions vary on whether it should be used. Some people recommend using contact cleaners or lacquer thinner or denatured alcohol to clean electrical contacts. Others suggest that WD-40 can be used to prevent carbon tracking and misfires in old-school distributor caps and to protect electrical contacts from moisture. It is important to note that WD-40 should not be used on moving parts as it is not a lubricant and can dry out and attract dust and dirt over time.

WD-40 is not a lubricant, but it can be used to protect electrical contacts from rust and corrosion
While WD-40 is not a lubricant, it can be used to protect electrical contacts from rust and corrosion.
WD-40 was first used to protect the outer skin of the Atlas Missile from rust and corrosion. It is a water displacement spray, meaning it keeps water outside of electrical connectors and prevents rusting. It can also be used to clean electrical contacts, removing dirt, oil, flux residue, and condensation from electrical equipment.
WD-40 is not recommended for use on electrical contacts and switches, as it can turn into a gummy substance that attracts dust and dirt. However, it can be used to protect electrical contacts from rust and corrosion, especially in enclosed connectors, as it won't collect dust.
It is important to note that WD-40 should not be used as a substitute for contact cleaners or lubricants designed specifically for electrical connections. While it can help prevent rust and corrosion, it is not a long-term solution and should be used with caution.
Additionally, when working with electrical components, always ensure that the power is turned off at the mains for safety.

It can be used to prevent carbon tracking and misfires in old-school distributor caps
While WD-40 is not recommended for use on electrical contacts and switches, it can be used to prevent carbon tracking and misfires in old-school distributor caps.
Distributor caps are a vital part of a vehicle's engine, protecting the terminals from moisture and debris while providing a connection point for each spark plug wire. A failing distributor cap can lead to engine misfires, poor fuel economy, difficulty starting the engine, and visible cracks or carbon tracking on the cap.
Carbon tracking occurs when there is a build-up of carbon on the contacts inside the distributor cap, causing misfires as the spark jumps to the path of least resistance. WD-40 can be used to clean the contacts and prevent carbon tracking, as it does not conduct electricity and will not cause issues with cross-connecting. It also provides lubrication, making it easier to disconnect the connector and helping to prevent corrosion.
However, it is important to note that WD-40 should not be used as a long-term solution, as it can turn into a gummy substance that attracts dust and dirt over time. Therefore, it is recommended to use contact cleaners or, in a pinch, lacquer thinner or denatured alcohol to clean electrical contacts.
To prevent distributor cap issues, regular maintenance is essential. It is important to keep an eye out for signs of wear and tear, such as cracking or damaged wires, and to replace the distributor cap if necessary. Additionally, condensation build-up inside the cap can be minimised by using a vented distributor cap or drilling small holes in the side of the cap to prevent moisture accumulation.

It should not be used on moving parts as it dries things out and attracts dust and dirt
While WD-40 is useful for a variety of tasks, it is not suitable for use on moving parts. This is because it dries things out and attracts dust and dirt, which can cause issues over time.
WD-40 was originally designed to protect the outer skin of the Atlas Missile from rust and corrosion. It is not a lubricant, although lubrication is one of its side benefits. However, it should not be used on moving parts as it is not a lubricant and can dry out these parts, making them prone to attracting dust and dirt.
Over time, WD-40 can turn into a gummy substance that attracts dust and dirt. This can cause issues, especially with electrical contacts and switches that move, such as in a switch. Therefore, it is recommended to use contact cleaners or, in a pinch, lacquer thinner or denatured alcohol to clean electrical contacts.
While WD-40 can be used to clean electrical contacts, it should not be the primary method. It is important to note that it should only be used on electrical contacts and switches that are not moving parts.
Additionally, it is crucial to exercise caution when using WD-40 on electrical connections. It is advised to turn off the power from the mains before checking electrical components.
