A lot of companies are pumping out "green" products these days, but from what I can glean there is a spectrum of environmental safety to be aware of. I have in particular been attempting to use more environmentally safe household products (soaps, detergents, etc), although it seems like with cleaning it's hard to avoid using toxic materials.
Cars are a good example. I received a tip from a website a while back that claimed you should always get your car washed by a professional rather than doing it yourself, due to the lack of "green" products for cars on the market (which is true, I've never actually seen any, although I'm sure they're out there). But, that also means you'd need to find a "green" car wash of some kind, right?
