It really DOES work! It doesn't smell or scratch surfaces. Not sure what is in it but it only took a part of a packet to clean the hard water stains from the toilet.
This stuff is great! I had used it several times in the past and was thrilled to find it on AMAZON finally. It works great! If you follow the simple directions: wet surface, rub small amount into stain - it works with very little effort. I've used it on my auto windshields and also on exterior windows of an older house.
Finally found something that works on our water stained toilet bowls!
Great product! I ordered it out of desperation after recently trying a much recommended cleaner which did nothing! I have been fighting water stains in our toilets for more than 29 years with every product I could find on the shelves in many stores and nothing worked other than pumice stones which cleaned but scratched the bowls. We have a well, a water softening system and still the stains persisted. The water line in the bowl was the biggest problem but 2 packets of Brite & Clean per toilet and just a little scrubbing made our 5 year old toilets look like new. I don't think I have ever been so pleased with a cleaning product!
