One of my very favorite natural, non-toxic cleaners that you can find right in your own pantry is baking soda. Of course, there are many uses for cleaning with baking soda (many of my favorites are listed at: Baking Soda Uses on HappySlob.com) but one very easy use you can try right away is to replace your harsh, chemical powdered cleansers with good old baking soda.
It's especially great for cleaning out pots and pans, scrubbing the bathtub, or cleaning out sinks. Just sprinkle the baking soda on, scrub it with a scrubby sponge, and rinse away the gunk and goo. :) It'll look great!
