Promising review: “I have well water. Something in my well water reacts with the copper pipes and turns my shower tiles blue. Since the color of my bathroom is not in the blue spectrum, this is problematic. The well water also causes a film to quickly form on the shower glass. I’ve tried dozens of cleaners and scrubbed until my arms hurt trying to stop the blue and the dirt.. My goal in life is NOT to be a full-time bathroom scrubber! I saw this stuff on a professional cleaner’s TikTok (sorry, I don’t remember which one) and thought: Whatever, I can give it a try. Oh my god, the first day after my shower I sprayed the stuff everywhere and walked away. The next morning the blue was much less visible and the glass looked clearer too. The second day I sprayed again and walked away. The next morning the blue was gone except for a few spots on the floor tiles and the glass looked fantastic. The third day I sprayed the remaining spots and the next morning the shower looked practically new. NO SCRUBBING AT ALL!!! This is my new favorite shower cleaner. The ONLY downside is that I have to sneeze when I spray in the shower, but I can live with that.” —LJ Petillo
