How can you trust the new “green” cleaning supplies for your home?

Where is the proof that they clean as well as Pinesol or Clorox. I am not really concerned except for the bathrooms. But I just don’t know how to believe them. I am so sensitive to the smells of the stronger cleaners that my throat hurts and I get headaches from the fumes. I would love to change but I need to know they really clean.
