Review on 2-Pack BAR KEEPERS FRIEND Powdered Cleanser - 42 Oz Total for Effortless Cleaning by Daniel Bates

The agent suggested this to me when we bought a house with the glass roof burned from debris. The bartender's friend immediately cleaned everything. We also had a fiberglass tub with a discolored bottom where we tried on a few things. I wet the tub, sprinkled Bartender's Friend on the floor and let it sit for about an hour. I rinsed the bottle and wiped it with a rag and the discoloration was gone. I also used it to clean a scratched fiberglass sink that was looking so bad I was thinking of replacing it. Needless to say, there's a can of Bartender's Friend under every sink in the house.
