My husband I and I recently moved into a home with a glass shower door. I was looking for something that I could merely spray on my shower door (without scrubbing or using a squeegee) after my daily shower to prevent hard water stains from forming. The label on this Tilex product claims that it will prevent soap scum and hard water buildup without rinsing, wiping or scrubbing, so I thought I would give it a try. I thoroughly cleaned my shower door and then used this product for a month. Even after that amount of time it did not maintain the cleanliness of the shower door. This product seems to work fine when doing my routine, bathroom cleaning, but it does not prevent hard water stains in my shower. The one benefit of this cleaning product is that the scent of the product is not overwhelming. It just makes the bathroom smell freshly-cleaned, not like other products where you can't be in the same room after they are used.
