Chris The cleaning instructions from the manufacturer are "rinse with warm water and dry with a microfiber cloth or chamois." They claim it is pretty non-stick. They also say its resistant to a lot of non-abrasive cleaners like windex, ispropyl acohol and vinegar. It is a little harder than the gel coat on fiberglass.
I suspect that if you had very hard or rusty water it would mark, but whether that would be worse than tile or fiberglass I have no clue.
