One of the few major problems with using an express car wash to clean your car is that it may damage your antenna. Antennas are sometimes damaged when you use a car wash service because they can be bent by the rotating brushes. If you have a car with a long radio antenna, and you want to take it to the car wash instead of washing it by hand, there may be something you can do to protect your antenna from the car washing process. This is only the case for certain types of cars though, and if your vehicle is the wrong kind then unfortunately you will have to wash by hand or risk your antenna.
Ways to Protect Your Antenna
In some of the more modern cars, the radio antenna automatically goes down into the car when the radio is turned off, and in some older models it is possible to push it down manually. If you don't drive a car with a collapsible antenna, then chances are that you can unscrew it and remove it from the exterior of the car before you go through the car wash. In some cases, you have to use a small wrench or pliers to loosen and remove the antenna. These methods help to protect it from the rotating brushes. If your car doesn't have a collapsible or removable antenna, you can always go to a car wash that doesn't use the brushes. Some car wash services use only water pressure to clean, and at those places you do not have to worry about your antenna.
