The Environmental Protection Agency (EPA) reports that air inside the typical home is 2-5 times more polluted than the air immediately outside, which is largely due to cleaners and other toxic household products.
For example, according to the Centers for Disease Control and Prevention, 1,4-dioxane is considered by the State of California to cause cancer and has been found to be potentially toxic to your brain and central nervous system, kidneys, liver and respiratory system. 
Two-thirds of laundry detergents tested by the Organic Consumer Association contain 1, 4 dioxane.  The highest levels were found in Tide (55 ppm), Ivory Snow (31 ppm) and Tide Free (29 ppm).
Following "natural" brands tested completely free: Clorox Green Works, ECOS laundry detergent (Earth Friendly Products), Life Tree laundry liquid, Method Squeaky Green laundry detergent and Seventh Generation Free & Clear laundry detergent. 
You can also make your own natural cleaners using baking soda, vinegar and lemons!
Vinegar diluted with water can clean almost anything in your home: windows, floors... it even can be used as a fabric softener. Baking Soda is great to scrub your bath and kitchen. Just sprinkle it on the surfaces and scrub. You may add a little lemon or organic essential oil such as lavender.
For a great non-toxic drain cleaner, sprinkle one cup of baking soda down the drain, add one cup of apple cider vinegar and let it bubble for 15 minutes, then rinse with hot water.
Clean Your Home Naturally ;-)
