Should have taken before and after photos
This cleaner is so fantastic at cleaning stubborn mildew stains on grout, tiles, floors, toilets and more.  I had a dark ring around the bottom of the toilet that nothing worked on, not even bleach. One spray, I left it on stain for 5 minutes and wiped clean. Stain was completely gone.  I wish I had taken a before photo.  I also had some mildew on my bathroom vanity and was contemplating having to re caulk.  Again one spray and boom stains gone and grout was white again. Needed to contact seller for some questions and an extra sprayer and customer service responses were excellent. Follow directions and use in well ventilated area.
