Love this stuff, but with caveats. First of all this is a maintainer, not a heavy duty cleaner. If your tub/shower has a 3 month buildup of soap scum, you'll need a heavy duty cleaner to get rid of it or, better yet, just move. I hate the packaging. Because it makes everything so slippery, it makes holding the 1/2 gallon container in one hand and the sprayer in the other, very dangerous. Just transfer some into a smaller spray bottle & use the other hand to cover your nose & mouth with a washcloth to avoid breathing the mist. It's supposed to be non-toxic, but not fun to breathe. This is my 3rd bottle!!
