Baking Powder Uses
Everybody knows how useful Baking SODA is. Did you know that Baking POWDER can be just as useful in keeping your home clean?
Baking soda is actually the primary component IN baking powder, so it's no surprise that pretty much anything you can do with baking soda, you can do with baking powder. If you get confused between the two, baking powder usually comes in a can. Baking soda usually comes in a box.
Since most people use far more baking soda when cooking, they often end up with leftover baking powder that has expired. Here are some great uses for your old baking powder.
One of my favorite uses, it really does well with odors. Mix in a drop or two of your favorite fragrance, and sprinkle on the carpet. Let sit for 10 minutes before vaccuuming up.
Sprinkle the baking powder onto your counter, sink or tub. Use a wet sponge to scrub out the stains, and then rinse clean.
Dishwasher / Washing Machine
Sprinkle some baking powder into your washing machine or dishwasher to add an extra boost of cleaning power.http://bellevuewashingtonblog.blogspot.com/2007/02/baking-powder-uses.html
