Wow, this stuff is crazy.. I first started using it about 10 years ago when I worked as a Commercial Janitor. We used it for the bathrooms. This Kaboom works instantly, and helps remove rust stains immaculately.

However, not too good for my health, and I feel bad it going down the drain. It is so toxic.. I wear gloves no matter what cleaner I use, but this will make you get dizzy and pass out. I started using a face mask at work. I also bleaches your clothing and my skin too!! I got red and itchy little bumps on my forearms and just above my wrist. Also, when some of the water and Kaboom got into my gloves, the top of my hands got a bad rash I need a steroid cream for from the Doctor by prescription.

There are many other "Environmentally Safe" products that work just as well without all the con's. Like CLR for example I wouldn't buy this again.
