What a waste of money. I bought three of the Kaboom Foaming Toilet Cleaner (as a set) for $19.95. It does not work as advertised. It takes about twice as much powder to make it foam up to the rim of the bowl, and it does not remove stains. You still need to scrub it. Worse, after about a month, the powder in all three containers became rock hard, even though they were tightly capped. I couldn't get it out, it wouldn't break up. After scraping it out with a garden tool, it would not foam AT ALL. E-mails to the company's customer service department have gone unanswered. Don't spend your time or money on this stuff.
