All of us probably experience this problem to varying degrees – stubborn-stained toilet bowls. Unless you have a domestic helper, i highly doubt many of us are disciplined enough to clean the toilet bowl regularly. Over time, stains that build up at the bottom can no longer be removed by brushing. If it bothers you, then i have good news for you.
I just tried it, this product really does what it claims, clears up the stubborn stains. I’m really happy with the result, and i think you will be too.
