It worked great on hard water stains on my bath fixtures and fair enough on floor grout but there were clumps of powder everywhere which I didn't like. If I try it again I will attempt to make a paste or buy the liquid formulation.

Works as Advertised and I mean that as an extreme compliment! I cannot remember when a product actually produced the 'wonderous' results that are talked about, but this one did.

This completely allowed me to clean the dirtiest of pots and pans. Burned in crud disappeared!

We have one of the newer bathtubs with the "built-in" non-slip strips on the bottom. After three kids with filthy feet get in the tub, just try and remove the stains from these strips. I tried regular cleanser (Ajax, Comet), Clorox Clean-up, pure ammonia, pure undiluted bleach -- Nothing worked. In desperation, I tried Barkeeper's Friend. It worked. It didn't get out all of the stains, but at least the tub looks good enough so that I don't have to worry if a guest peeks behind the shower curtain to check out that aspect of my housekeeping. I noticed it's also great for cleaning the chrome faucets in the tub -- removes the dulling water residue and keeps them looking shiny for days on end. It's also great for getting stains and odors out of cookware and plastic food storage containers. Great product!

When it comes to keeping my stainless steel pots and pans looking like new, bar keepers friend is always by the sink. Doesn't take alot of powder to be effective, leaving my stainless steel looking new, removes grease and oil stains. Make sure to rinse thoroughly so as to not leave powder residue.
