Eco-Friendly Cleaners

As I've mentioed before, living in the country gets you to thinking a little bit more about where your water comes from - and where the waste water is going - and what it contains when it leaves.
For as long as I can remember, we've always used bleach to clean our toilets and wash our whites. I've been doing that since moving here, but it's time to change. Not only is bleach bad for the environment, no matter where you're at, it kills the good bacteria in the septic tank as well.
I haven't finished my research yet, but here's a website with some environmentally friendly cleaning products.

Do you use something besides bleach to clean and whiten your clothes? Tell me about it.
