We like to try new car washes. California Suds City Car wash is a keeper. It's not overly expensive. It's a do it yourself car wash. They have special hoses so as to reach even the tallest of vehicles or trucks. It's easy to find located on Thomas Johnson blvd. which is one of the main streets in Frederick county. It's never super busy so you never really have to wait in line to wash your car. We always bring our own towels to dry , they do not supply those.
