When we purchased our almost 100 year old house, we found a lot of rust and build up on the faucets and showers. So we purchased this to help remove what was built up. It worked wonderfully at removing it all!
I was not impressed with the Great Value Devil's Food Cakes. The package I purchased tasted old and crumbled in my hand. I checked the expiration and it showed it was still good. I guess I just got a bad batch.
