Cleaning the shower is a job I absolutely hate. My arms and back hate it too. So I was excited when I found a spray cleaner that eliminates the need to scrub. Arm & Hammer has been making quality products for years and this is another success. It comes in an easy to hold spray bottle. You start with a clean shower, then after each shower from then on, you spray this on tile, shower curtains and doors, tubs, etc... That's it! No rubbing, scrubbing or rinsing needed. It prevents the buildup of soap scum and mildew if used regularly. It has a fresh scent that isn't bothersome. It's fast and easy and best of all, it works! There is no bleach and it is safe for use on most shower/tub surfaces. However, it is not recommended for refinished tubs, natural stone or marble. You can use it without cleaning your tub/shower first, but it is strongly recommended that you clean before the first use. Now, if they'll just come out with a product that will totally clean toilets!
