Promising review: “I thought my hard water stains would never come off my shower doors, but I bought this awesome brush set, and it’s amazing! I’ve tried all the hacks — drier sheets, clean erasers, lemon, vinegar — nothing works like this brush! I used Zep shower cleaner with it! In the picture, the side on the right is the part of the door I cleaned, and I still have to clean the left side.” —Traci D.
