WD-40 car tips every driver should know

Scotty Kilmer revealed all on his YouTube channel, along with some common uses that should actually be avoided.
Firstly, he revealed that you shouldn’t use the product to rectify drive belts as it can cause damage, and no one wants that.
Next, he revealed that even though it temporarily makes your car’s exterior shine, it can fade quickly and can actually damage the paint over time.
Using it to make your tires sparkle is also a bad idea, as it can reduce their grip and traction, making them dangerous.
But don’t worry, as it has some good uses too, and it can help loosen some elements that may be causing issues.

For example, under the vehicle itself, bare metal can be protected along with other rusted parts.
Plus, get ready to have your locks working like never before, as the mechanic shared that he had been using it for years without any problems, and highly recommends it.
Hinges can also work smoothly with WD-40, but remember to wipe the excess off after you’ve finished and use a silicone lubricant.
So, maybe the cheap product really can save you thousands, after all, there’s only one way to find out.
