Hand wash only, air dry...

Every time I take the truck to the car wash (usually once a week) they always remove the antenna. The kid has a small adjustable wrench in his pocket to remove it. The kid at the other end just reinstall's it by hand. I finish the job when I get home, the car wash must not be able to afford two adjustable wrenches lol.

They do have a sign stating they are not responsible for damage caused by not removing antenna or damage to non factory installed parts.
