The Works is the best toilet bowl cleaner I have ever used! You may have seen this brand in the stores and passed it up because it wasn't a name brand that you recognized. I am glad I picked it up years ago. I usually buy what is the cheapest or on sale, and that is how I happened to buy this at first. The cost is very low compared to other brands. I have even found The Works at the dollar stores.
We have well water and we get calcium and rust stains that are hard to remove in the toilet bowl. I have never had much luck with all the other name brands easily removing these stains. The Works is different, it immediately takes away the stains within seconds and I don't even have to scrub hard. It comes in a curved neck bottle that makes it easy to get under the rim. It does have a strong smell, so you want to be careful while using it. I won't use any other toilet bowl cleaner, because this really does work!!
