We have recommended it to several relatives and friends

Wow! What an amazing product. I was a little skeptical at first, but after trying it on my rental car I was blown away. It actually removed a huge coffee stain that I thought would be impossible to removed. My wife also uses it constantly to clean out the tub and the tile floors. She loves the Z Stuff, as she calls it. We have recommended it to several relatives and friends. We can't live without it now. Thank you so much.
