Hard water sucks.  It just does.  If you've ever stared at hundreds of water spots on your glass shower door, you know what I'm talking about.

You know what sucks more than spotty-mineral-water eyesores?  Cleaning them.  Before I knew better I once spent 45 minutes with a bottle of windex and a couple rags trying to clean my glass shower door.  No bueno.

Then I discovered Vinegar-based cleaners (you can even use a diluted mixture of water and household vinegar) and our favorite - Lime-away.  Spray it on, wait a few minutes and wipe it down.  Voila! Now you have clean glass and 40 minutes back in your day.  Win win.
