I have the same concerns about having a non-toxic household. I make my own laundry soap, use ecover in my dishwasher, clean with vinegar, baking soda, salt, lemon -- you get the idea. I feel pretty comfortable with this stuff. I wouldn't DRINK it, but I've done some pretty intense cleaning with high concentrations and no gloves, and my hands don't have that chemical feeling that they used to when I cleaned with mainstream products.
(I also have tile & grout countertops so I completely understand the challenge of getting it clean without bleach.)
So that's my .02!
