A recent AOL Autos column featuring Lauren Fix, who's also knows as The Car Coach, addresses the topic of carwashing.

The July 10 column featured a question from one reader who asked: Whenever I cue up at the carwash, there are choices for waxing, undercarriage washing, etc. It's hard to believe that any of this quickie stuff is worth it. Am I right?

Fix answered, "A quick carwash is just that, so keep in mind that all carwashes are not created equal. Washing your car once a week is critical to keeping it shiny and protected. It also can protect your investment ― your resale value. When you add up the costs of regular cleanings, you'll still might be ahead when it's time for a new car."

Fix also talked about the benefit of hand carwashes and what to do if you want to wash your car at  home. To see those answers, click here.
