1. A shower door cleaner to remove the stubborn hard-water spots that make your glass look gross and foggy. Once you use it your glass panels will be so clear that you might accidentally walk right into them.
Promising review: "This product works beautifully. I tried a lot of products to remove the hard water from my glass shower. I have to admit the first time I used it with a cloth it was not very effective. The second time I used a nonabrasive sponge for glass, it turned out beautiful just like the first day the glass was installed." —EJP
