Great for travertine tile
We had our travertine floors cleaned by a professional cleaning service and they recommended this product.  It really gets the floors clean and returns them to their original state.  We have large grout lines that it also cleans well.  A little goes a long way so the bottle will last a while and it's ph neutral - so safe for travertine.  We also use it on our granite counter top and it is streak free.
