Therefore, he named the formula as WD-40.

WD-40’s formula is a trade secret. But we can be sure that WD-40 does not contain silicon, kerosene, water, wax, graphite, chlorofluorocarbons (CFC) or any known carcinogens. However, some professionals recommend wearing gloves or even goggles when using WD-40.


(2) Is WD-40 almighty?

We know that WD-40 is versatile. There are countless folklore and videos online of its usage. However, being versatility does not mean it is applicable on everything. The almighty phenomena are created by different topics. In fact, there are times that WD-40 isn’t applicable.

(4) When shouldn’t we use WD-40?

The general impression that WD-40 gives to the public is that it can be applied on any metal surface, especially the metal parts that are often subject to friction, such as door hinges. Is that true?

Answer: WD-40 is not a lubricant. As mentioned above, it is a water displacing tool. Its main function is to remove rust and decontamination by removing water and moisture.


Why WD-40 has a function that is similar to a lubricant?

Answer: The lubricating effect doesn’t come from the formula of WD-40, but the condition that appears after WD-40 dissolves the substance. The most direct explanation is that after using WD-40 to remove rust and decontamination (such as door hinges), as the door hinges are clean, it looks like it has lubrication effect, but this effect will not last. (The material that makes the door hinge no longer smooth is removed by WD-40, so it seems to be lubricated). 

Therefore, if you want to lubricate the door hinge, you can’t do it with WD-40 alone! After applying WD-40 to clean the door hinge, you should apply professional lubricant to complete the entire lubrication process.


(5) Can WD-40 be applied to any metal surface?

There was a situation that a solider used WD-40 to maintain the firearms as he didn’t have any other professional tools to use. In the absence of professional tools, the versatile WD-40 can substitute the professional product. Although this is not a perfect method, it can help achieve the purpose. However, further repair work should be carried out afterwards. Experienced people do not recommend using WD-40 solely to maintain or lubricate firearms, because the moisture absorption of WD-40 will attract dust and dirt. If only WD-40 is used without proper professional lubricating oil, it may accelerate the rust of the firearm.


(6) Never spray WD-40 on bicycle chain!

WD-40 can remove the dirt from the bicycle chain, but it will also damage the bicycle chain, so “Never spray on the bicycle chain! “.
