Day three I sprayed the remaining spots and the next morning the shower practically looked new. The next morning the blue was gone except for a few spots on the floor tile and the glass looked amazing. The next morning there was a NOTICEABLE reduction in the blue and the glass looked clearer too. My ambition in life is NOT to be a full time bathroom scrubber! I saw this stuff on a professional house cleaner's TikTok (sorry, don't remember which one) and thought 'what the heck, might as well give it a try.' Oh my goodness, the first day after my shower I sprayed this stuff all over and walked away.
I've tried dozens and dozens of cleaners and scrubbed till my arms ached trying to get ahead of the blue and scumminess. The well water also causes the shower glass to film up quickly. Since my bathroom color scheme isn't on the blue spectrum, this is problematic. Something in my well water reacts with copper plumbing and turns my shower tiles blue.
