OK, this works! My shower has never been this squeaky clean. 1 cup White vinegar heated up (microwave 1-2 min) with equal amount blue Dawn, gently shake and spray on and wait and then wipe away the soap scum. Thank you Pinterest!
Use Easy Off Oven cleaner to clean fiberglass shower floor. Easy Off in the blue can cold method oven cleaner!!! Works perfectly! EZ Off fume free shower cleaner. Spray on floor, let sit 30 min to 1 hour scrub with stiff pad or brush (use gloves) and rinse well with hot water.
