Tonneau covers are panels that fit over the open cabin of a pickup truck and come in different kinds.  And if you’re getting your car washed, chances are that your tonneau cover needs some washing as well. Here’s what you need to know! Hard-top tonneau covers are probably the safest when you go into car washes since the brushes won't damage them. However, the brushes might scratch any paintwork you might have done on the hard-top tonneau. Soft tonneau covers are also advertised to be safe to bring into a car wash. Different tonneau manufacturers assure that you can safely go through a car wash without removing your soft tonneau cover. However, it is advised that you remove the soft tonneau cover.  Since these are usually attached by velcro or straps, removing them isn't that hard.
