What You'll Learn
WD-40 is not a lubricant
WD-40 is a popular multi-use product that has been used for various applications, including as a lubricant. However, it is important to clarify that WD-40 is not a traditional lubricant in the sense of providing prolonged lubrication between mating parts. Instead, it serves as a solvent and a temporary lubricant.
The confusion surrounding WD-40 being a lubricant may arise from its ability to penetrate and clean mating parts that are stuck. While it can help loosen and clean these parts, it does not provide long-lasting lubrication. For constant motion and varying temperatures, a grease-based lubricant is more suitable.
Additionally, WD-40 dries out and does not maintain lubrication indefinitely. It may even leave a residue that can collect dust over time. This characteristic makes it unsuitable for certain applications, such as cleaning electrical connections or sensitive car sensors.
Furthermore, the "W-D" in WD-40 stands for Water Displacement, indicating its ability to repel water. This property, along with its solvent nature, makes it effective for removing rust, corrosion, and sticky substances. It can also protect fishing equipment from corrosion and rust, although it is not intended to attract fish.
In summary, while WD-40 may provide temporary relief in certain situations where lubrication is needed, it should not be solely relied upon as a lubricant. It is essential to understand its limitations and use it in conjunction with a proper lubricant for specific applications requiring long-term lubrication.

It can be used to clean plastic
WD-40 is a versatile, multi-purpose product that can be used to clean and protect various surfaces. It is a water-displacing spray that contains lubricating oils, petroleum distillates, and other proprietary ingredients that work together to penetrate, lubricate, and protect surfaces. While it is a popular household staple, there are some considerations when using WD-40 on plastic surfaces.
WD-40 can be used to clean plastic surfaces and restore them to their former glory. It can be applied to a rag and then used to wipe down plastic surfaces, giving them a shine. This is especially useful for plastic parts on cars or garden furniture that may have become discoloured or dull over time.
However, it is important to note that WD-40 is not specifically designed for use on plastic. Over time, it can attract dust and become sticky, potentially worsening any existing problems. Additionally, its solvents may damage certain types of plastic, so it is important to use it with caution. Soft, rubbery plastics, for example, are generally more sensitive and should be avoided.
To avoid potential damage, it is recommended to use products specifically formulated for plastic. There are plastic-safe alternatives available, such as silicone-based lubricants or gels, that can be used on polystyrenes and polycarbonates without causing harm. These alternatives can provide lasting results and are better suited for maintaining plastic surfaces.
While WD-40 can be used to clean and polish plastic, it is important to weigh the benefits against the potential drawbacks. For occasional use, WD-40 may be a convenient option to enhance the appearance of plastic surfaces. However, for long-term maintenance and protection, specialised plastic-safe products are a more suitable choice.

It can be used to polish plastic
WD-40 is a versatile, multi-purpose product that can be used to tackle a wide range of tasks, including cleaning stains and protecting metal fixtures. It is a water-displacing spray that was originally developed in 1953 to prevent corrosion on nuclear missiles. The name "WD-40" stands for "Water Displacement, 40th formula", signifying that it took 40 attempts to develop the product.
WD-40 can also be used to polish plastic. While it may not be the best product for this specific application, it can be applied to plastic parts to give them a shine and restore them to their former glory. For example, it can be used to spritz up garden furniture or car parts made of plastic.
However, it is important to note that WD-40 is a solvent, not a lubricant, and it should not be used as a permanent protectant for metal surfaces or a primary lubricant for door locks. Additionally, when dealing with plastic components, it is recommended to use products specifically formulated for plastic to avoid potential damage. This is because WD-40 contains aliphatic hydrocarbons, including naphtha, which can cause certain plastics to become sensitive and potentially damaged over time, especially if exposed to high temperatures.
If you do choose to use WD-40 to polish plastic, it is suggested to wipe the surface down with a damp cloth afterward and avoid using it on softer, rubbery plastics that may be more sensitive.

It may damage certain plastics
While WD-40 is a versatile multi-purpose lubricant, protectant, and cleaner, it may not be suitable for certain applications, including some plastics.
WD-40 is a water-displacing spray that contains lubricating oils, petroleum distillates, and other proprietary ingredients. It is important to note that WD-40 is a solvent, not a lubricant. While it can be used to polish plastic, its solvents may damage certain types of plastics over time. This is because many plastics are derived from petroleum products and exhibit sensitivity to petroleum-based solvents like WD-40.
The sensitivity of plastics to WD-40 depends on the specific type of plastic. For example, plastics such as ABS and polypropylene (commonly used in old video game controllers) are mostly stable when exposed to naphtha, a component of WD-40. However, prolonged exposure at high temperatures may eventually lead to significant changes in the plastic.
Softer, rubbery plastics, such as those covering joysticks, are generally more sensitive to solvents like WD-40. To avoid potential damage, it is recommended to use products specifically formulated for plastic. There are plastic-safe silicone lubricants or gels available for components made of polystyrene and polycarbonate, which will prevent damage while providing lubrication and protection.
Additionally, while WD-40 can be used for hinge maintenance, it is not designed as a primary lubricant for hinges. For long-term lubrication of hinges, a PTFE-enhanced silicone lubricant is recommended. This provides superior and long-lasting lubrication, whereas WD-40 may attract dust and become sticky over time, potentially worsening the problem.

It can be used on plastic car parts
WD-40 can be used on plastic car parts, but it is generally advised against. This is because WD-40 is a Water Displacement formula designed to remove oil, grease, and other watery substances from solid surfaces. Hydrocarbons in its chemical formula can break down the chemical bonds of certain plastic polymers, causing the object to soften and become brittle over time.
However, not all plastics will be damaged by WD-40. Amorphous polymers like polycarbonate, polystyrenes, and PVC are vulnerable to WD-40-based erosion, while crystalline plastics like polypropylene, polyethylene, polyester, and nylon are more resistant. As it is difficult to differentiate plastic polymers at a glance, it is generally safer to avoid using WD-40 on any plastic surfaces.
Despite this, some people have reported successfully using WD-40 on plastic car parts to clean, degrease, and lubricate them. WD-40 can be effective at removing oil and grime from plastic surfaces, and some users have found that it rejuvenates plastic, making it look brand new and improving its flexibility. However, one of the downsides of using WD-40 on plastic is that it tends to attract dust, leaving a greasy film on the surface.
For these reasons, alternative products like furniture polish or SuperSlickStuff are often recommended for cleaning and polishing plastic car parts. These products can provide the same rejuvenation effects as WD-40 without the same degree of dust attraction. Overall, while WD-40 can be used on plastic car parts, it is generally advisable to use alternative products to avoid the potential risks of erosion and dust attraction.
