How to Get Rid of Hard Water Stains

[Dylan Barnard]

Hey BP,

We bought our first investment property this week and there are some really difficult hard water stains on an all glass shower. I have used some industrial glass cleaner and tried vinegar for it's acidity, to no avail.

We are in Texas, so our water here sucks cuz of all the fracking. I'm thinking we need to replace the glass to have it looking new, but I wanted to ask you all before spending more money. Any tips or tricks to help?
