I wanted to apply Rain-X to the inside of glass walls in the shower to minimize upkeep and prevent further water stains. But if possible, I would like to get the glass really clean first. The previous owner did very little upkeep and the glass is covered with water drop stains.
I already tried Windex and lemon juice with little results.
I'll post a picture if necessary to show the type of stains.

CLR is best for removing buildup from calcium, lime, and rust. Just use it with care (well ventilated, and probably don't want it on your skin).
