Awesome works great on tile or one piece fiberglass showers... but honestly, my hubby trained me on how to make shower cleaning easy... WE have a small squegee that we use on the walls and that keeps all the hard water fillm, scum , etc from forming.. I merely spray it with Awesome or another " green" cleaner once in a while other wise u can't tell our shower gets used.. * and YES for any of u smarty pants out there... we DO shower daily!!!!*. Even when we had a glass shower... never a water mark or film.... I'm all for anything that makes cleaning easier and faster!!
