While the rain may seem like a free and convenient way to rinse and refresh your car, it can actually do more harm than good. Any mechanic or auto expert will tell you that the most important time to wash your car is right after rain, but not many people understand why. Let’s review why rain is bad for your car so you can take the appropriate steps.
Pollutants in the Air
While you can’t see them, pollutants and contaminants in the air mix with rain as it falls. As the rain pelts your car, these pollutants get left behind. Once the water evaporates, they create marks and stains that can compromise the exterior of your vehicle or ruin the paint.
Acid rain is the worst reason why rain is bad for your car. Acid rain forms after enough pollutants have entered the rain. This rain begins to wear down your car’s exterior. The best way to get rid of this layer of pollutants and avoid rust and corrosion is to polish and buff the paint. This way, you thoroughly ensure you eliminate the contaminants from the pores of the exterior. You can avoid any unsightly defects to the paint.
To protect your car from a literal force of nature, consider handwashing your car and applying coatings of wax. Regular washing will eliminate stains and contaminants before they have a chance to really stick around and start causing problems. But it’s important to follow up with wax. Wax not only keeps your car looking glossy and fresh, but it also creates a protective layer that will shield the paint from contaminants. If you’re willing to go the extra mile, having your car detailed with a ceramic coating can help. This type of coating is naturally hydrophobic.
