Bests & Worsts Reviews from Amazon

This product is a complete waste of money. It tells you to scrub the toilet first for best results, which I did. It says it gets rid of every kind of water or other stain and to leave it in as long as possible. I scrubbed the toilet but didn’t get out every mark.... left it in for 7 hours and it didn’t remove one stain or Mark more than what I scrubbed. It did bubble up whe tossed in the water....
