One of the most important times to wash your car is immediately after a rainfall. Many people think that when the car sits under the rain, the rainwater will wash the dirt and salt off the car. Not true. Actually, rainwater can cause even more damage than it helps. Here’s the other answers to, “Why Wash Your Car After It Rains?”

As rain falls, it collects pollutants and contaminants from the air, and this is called Acid Rain. The only way to remove the etching is to polish and buff it out with a dual action polisher and professional-grade buffing pads. Even after a short rainfall, rainwater and pollutants collect on your vehicle. The rainwater eventually evaporates, leaving a thin layer of pollutants that can damage your car’s finish.

The longer you leave the pollutants and contamination on your vehicle’s finish, the more damage it will inflict on your car’s paint finish.

If you have a microfiber drying towel handy, go ahead and wipe off the car so that the water spots don’t sit on the surface of your car’s paint. Snow and sleet can also result in some damaging effects and are often compounded by chemicals in road salt. Road salts are very harmful to a car’s paint surface.

Many people are very busy, and time always plays a factor. In reality, washing your car, even once every two weeks, can be a great way to protect your car from the salt that can eat away at the exterior of your car and create rust. When you do get your car washed, make sure that you wash it with clean water. Avoid any car washes that use recycled water to wash your car. Hand washing at home is always the best. Many car washes use very aggressive “soaps” that will strip away any wax or sealant off your car’s paint finish.

Do not assume that the rain is going to wash all of the contaminants off of your car.

In fact, it is often a good idea to head straight to the car wash after it rains or the temperature is warmer than 35 degrees. This is because contaminants may actually eat away at the exterior of your car faster when it gets warmer out. It is recommended that you get a protective finish that will keep the contaminants (including road salt) from doing too much damage to your car.

Consider a Ceramic Coating Treatment

Ceramic coating paint protection is immune to road salts, dirt, and grime.

To sum up the point of this car detailing tip, hand wash your car as much as possible, especially after driving through dirt, road salt, near the ocean and also after it rains.
