As a house cleaner, i found this shower cleaner is the best on the market by far. I have a stand up shower with glass doors, and I just spray, wait, and rinse. Works every time, no matter how much soap scum there is. I have suggested this product to everyone I know. It is great for my mother so she doesnt have to climb in her shower and scrub. Please dont ever stop making this mega sprayer! I dont want to go back to the way I used to clean!
