It's only fair at this point to pause and talk a little bit about Thieves. Since it is far too new of a product to be on the Environmental Working Group's radar and grading system, I am going to take the liberty of grading it myself. Keep in mind, I am not a scientist and have zero credentials to give this grade. I am doing nothing more here than looking at the facts, stacking them up against other products listed in EWG's database and finding out where it fits. You won't be surprised when I tell you after much research, I can conclusively tell you, without a doubt in my mind, Thieves Cleaner gets a solid A grade. Why? Well, just look at the graphic for the details. This product speaks for itself. Between the list of solid, earth and body friendly ingredients, and its amazing cleaning powers, there just isn't another cleaner I will have in my home.
