I hate cleaning the bathroom. I have glass shower doors. I live in Arizona, which has the hardest water I've ever seen. I have tried multiple products to try to remove the built up soap scum/hard water deposits from the shower doors, but none have worked. Until now. From the first application, I could see an improvement, which encouraged me to use the product again. Everything else I've tried was like using plain water, so I gave up until something else came along. After three applications of the Mega Shower Foamer, one or two days apart, I think I will actually have clear, shiny shower doors again. I look forward to wiping down the shower doors each time so I can see how much better they look. Which is hysterically funny to me.
