How about the Sierra Club won't divulge how much money its getting from Clorox? And even worse, the Sierra Club can't endorse any other cleaning product, no matter how much better it may be for the environment.
Oh, any my favorite detail about the Clorox cleaning products: the products are petrochemical free...except for the petrochemicals used to create the "fresh" scent and the green coloring.
You can read more about the deal at Fast Company (landing page will probably be an ad).
