It is superconcentrated. I have had the same 16 oz bottle for over a year and have only used half of it. I use it for every cleaning purpose around my house. It is safe for use around kids, pets, people with allergies ,etc.
Just mix it according the the directions for the right job. It cleans windows, flat-top stove, mopping, all-purpose, kitchens, baths, grills, out-door patio furniture. you name it, it can clean it well!
I hope this helps.
