This is my MOST favorite thing this week! It has saved my toilets from that blasted ring around the toilet!!! I found this at Bed Bath and Beyond. It only cost me a few dollars, like $4.99 or so, can't really remember. However, it is the ONLY thing that has taken off that line!!!! It's amazing!!!! So if you clean your own toilets go get one, today!!!! You can thank me tomorrow!!!
