Promising review: (I know it's super long, but it has great cleaning ideas!) "Brilliant product! So far, I've used it in four areas that were giving me trouble and driving me nuts. First, I applied the liquid to my smooth-top range, quickly removed all spill remnants, and when I rinsed the surface, it gleamed — much better than any cleaner I've tried so far. Next, I used the cleanser on my bathroom faucets, which looked terrible. They had water spots that wouldn't fade with anything I tried. I was seriously considering replacing them as they looked dated and old, but I made a paste with the cleanser and used the non-scratch dish cloth, and with virtually no scrubbing at all, every water spot completely vanished! Then, I applied the cleanser to my glass shower door, which was heavily coated in soap scum and water spots, streaks, and film. It took a bit of scrubbing with the non-scratch cloth, but the door was dramatically improved by about 75%. Finally, I used the cleanser in my toilet bowls, which had hard water discoloration, sort of a dark yellowish-orange color where the water comes into the toilet bowl. I just sprinkled it onto the stains and left to do something else, intending to come back and use the toilet bowl brush to scrub the stains; however, when I returned, they were all GONE. The stains had completely vanished! I was truly gobsmacked! I didn't even scrub the areas. The stains had not budged with foaming bleach sprays, cleansers with bleach, etc., so I am more than pleased with Bar Keeper's Friend. I'm planning to keep some on hand from now on, and I have recommended this product to my family." —History Chaser
