Automatic car washes seem like the convenient cleaning option — they are cheap, quick and situated almost everywhere. Initially, resorting to these services makes sense. You just drive your car in and after a few minutes, you drive out with a clean car.
On the contrary, the processes might cause damages to your vehicle.
The Deal with Brushes and Chemicals
Most automatic car washes use chemicals to loosen the dirt’s bond on your car paint. While it can clean effectively, it also contains strong acid, which strips your car of any protective coating such as wax, paint or sealant. If the chemicals fail, a rotating brush agitates the surface to create a more polished look.
According to Breen Panelbeaters, a South Auckland panelbeater, rotating brushes can thoroughly clean the car but scratch the pain in the process.
Too Much Pressure, Too Much Water
Automatic car washes use high-pressure water to remove the cleaners and excess dirt from your car. A blast of water ensures that the vehicle exits the shop perfectly clean.
While water blasting is effective, the high pressure sprays excess water into the cracks and crevices of your car. Forcing water where it does not belong can cause serious damage to the car’s electrical components.
At the end of the wash, drying is necessary to remove excess water from the surface. Unfortunately, this is not enough to dry out the water from the cracks and crevices. When you drive off, the water leaks from these cracks, which leaves mineral deposits on the car’s surface. Over time, this will manifest on the paint and cause permanent damage. Some services offer a hand-dry option, which is the better alternative but only if they are using clean towels.
Automatic car washes can be good for your car, but only in moderation. It’s best to wash your car on your own. With a hand car wash, you keep your car safe, clean and sleek all at the same time.
