Amazing Product!!!
We were considering buying a new toilet because we couldn't figure out what to use to remove the yellow strains on the inner rim of our toilet. So we decided to give this product a try and with a little elbow grease, we now have a new toilet! We are so very happy we gave it a try. It removed the years of calcium buildup with using less than two inches of the stick.  I highly recommend this product, you will not be disappointed.
