Bests & Worsts Reviews from Amazon

I have used this product for about 6 months on our stubborn shower door. We have very hard water and I have spent hours scrubbing and cleaning with this stuff. I recently purchased "Bar Keepers Friend Liquid Cleanser" just to try something different and it is AMAZING!! I have wasted so much effort and time using this Rain X product. I did about a 1/4 of the effort with the Bar Keepers Friend and our shower door looks brand new!
