Query: safe as rain water

I believe it is safe as rain water. The only problem is that is all the more cleaning power it had. I used it as a prespray for a stem cleaning application and was totally disappointed. The spots I had before were still there, it may have removed about 10% of the the spot and I believe that is being generous. I cleaned other carpets with a product called "Awesome" that is for steam cleaning carpets that costs $6.30 a gallon with a lot greater success.
