    Default Cleaning a Soft Tonneau Cover

    We had the Chevy Bow-Tie Tonneau Cover put on our 2009 they day we purchased it new.

    It has gone through mostly automatic car washes.

    Since we have been having good weather, I decided to clean up clean up the truck and noticed the tonneau cover has what looks like mold.

    I used car wash soap and a scrub brush, but it only got some of it off.

    Simple Green. I use it on my Bimini cover on our boat. It gets any mold off with no issue and you can safely wash it down the driveway.
