Hello, recently moved to NZ and live in Rotorua, where we have the hardest most minerally water I've ever seen. My glass shower enclosure is rapidly becoming opaque.

We use a squeegie daily, have tried cleaners from the glass places, as well as commercial stuff available here. This is a rental house and I don't want to be penalized for a filmy shower. Any recommendations for cleaning mineral deposits off the glass?

I already tried the dryer sheet trick (using my few precious US bounce sheets) it didn't put a dent on it.

Any ideas will be tried and appreciated!
