Is Rain Bad for A Car? You should know this…

Although some areas see less rain throughout the year, rain is a universal weather condition, and every car in the world will see rain at some point. Most people see rain as harmless—it’s just water.  However, have you ever asked yourself, “Is rain bad for my car?”

In some cases, rain can damage a vehicle, but which form that damage takes depends on the type and severity of the rain. Standard rainfall can damage both the exterior and interior of a vehicle, freezing rain can cause significant body damage, and flooding can potentially destroy a car for good.

Let’s continue to look at some of the different ways that rain can potentially damage your vehicle and what you can do to prevent it.

Can Rain Damage the Paint on My Car?

If you are one of the many people who do not wash their car during the rainy season because you believe nature is doing it for you, you might want to continue reading to learn more about the ways that rain can damage your cars’ paint. 

First, rainwater is full of pollutants. Land water evaporates into vapor, which then condenses into small clusters of droplets. Once enough droplets have clustered, they form what we know as a raindrop. As that raindrop falls to earth, it becomes contaminated by the air. This type of rain is called acid rain, and when it dries on a vehicle, it produces watermarks. 

PHILKOTSE offers a great guide explaining what acid rain is, and how to remove spots from the exterior of your car.

Now we know how falling rain can cause damage, but what about bouncing rain? That’s right, rain can bounce, but not in the way you might think. Raindrops splatter when they hit the ground and splash up onto the bottom of your car. If you live in an area with high salt contents (either from the ocean or manually put onto the road) the rain could be splattering your car with salt. Salt is most recognizable by the white film it leaves behind once the rain dries and can have a corrosive effect on your automobile.   

Will Rain Remove Wax?

Car wax creates an environment where water collects into beads and runs off the vehicle. This helps to protect the clear coat of your car, which in turn will protect your vehicles’ paint. If the wax is applied properly, rain should not wash the wax off your vehicle, but it could reduce the lifespan of the wax.

Second, rain itself is not powerful enough to remove much of the dirt and grime that collects on the surface of a vehicle.

Finally, you must rinse a car off thoroughly when washing it to avoid shampoo drying onto and destroying the paint. Since most people cannot control the direction and flow of a rainstorm, there is a good chance you will not get all the soap off your vehicle when you wash it in the rain

Water that finds its way into the inside of your car can also cause issues with interior rust. Seat tracks, hinges, and other metal pieces can become rusted and may eventually become inoperable. You can prevent this by being vigilant and removing water from these areas as quickly as possible.

Damp, rainy conditions can cause problems with both the engine and electrical systems in a car. Many issues are caused by users driving through standing water, which splashes or sucks water into the engine. Even small amounts of standing water can become a big problem.
