Travertine turned geeen from water in shower

Question: We have a water softener and the salt has left green stains on the floor where the water hits the shower floor. What can I use to clean this off without damaging the travertine?

Answer: Try duPont StoneTech Professional Revitalizer Cleaner + Protector: http://amzn.to/1sjIP8c

We have tested this product on outdoor travertine with mildew and it removed it without any hassle.

Good luck!
