Bests & Worsts Reviews from Amazon

This stuff is a miracle. My husband & I just bought a house & there is very hard water. It looked like the previous owners never tried to get the hard water off the shower doors & walls. I tried vinegar & dawn first & it didn't even scratch the surface. I tried Scrubbing Bubbles next & it was the same as the vinergar/dawn solution. I was feeling so defeated. I did some research & bought Bar Keepers Friend. This did work when scrubbed with a grade 0000 steel wool piece. Unfortunately, it took me about 2 hours to clean a quarter of the window in my shower. My arm also felt like it was going to fall off. I was determined so I researched more. I found this stuff. I was so anxious that I cracked it open minutes after receiving it in the mail. I applied it to my grade 0000 steel wool & started scrubbing away. BINGO! It took me about 15 minutes to clean the same size section as I did with the Bar Keepers Friend. I'm not gonna lie, this stuff needs some elbow grease but it definitely works. It took off what seems like years of hard water stains. Maybe the people who are saying this doesn't work just aren't putting enough elbow grease into it. I've read people are bothered by the smell but it really didn't bother me. It does have a smell to it but it's not super harsh & totally able to withstand. This is going on my "always available in my house" list! I love this stuff!
