It will work. I've used Easy-off on fiberglass boats, to get rid of waterline stains, which are a lot dirtier than your shower ever should be.
I also use Easy-off (Fume-Free) in my shower. Followed by an application of Turtle Wax Ice in the spray bottle to make future cleanups easier (on all but the floor).
