Scrub out the toughest dirty dishes
Baking soda makes those dreaded dishes covered in dried crud so much easier to tackle. Dunk the dishes into soapy water, then sprinkle the trouble spots with baking soda. Let them sit a little while to soften. You can also add a dash of baking soda to the dishwasher for a boost in cleaning power and a reduction in funky smells. DO NOT DO THIS WITH GUEST DISHES, BUT RATHER USE FOR CREW AND GALLEY DISHES.
Pour a few tablespoons into a paper coffee filter or scrap of tissue paper, tie it up with a rubber band and stick it into a less-than-fresh-smelling shoe and it will absorb the odor without making a mess or damaging delicate materials like suede.
Eliminate musty smell in books
Mold growth makes old books, photographs and other stored items smell musty. Get rid of both the odor and the cause, excess moisture, by sealing the items in an airtight container with a large, open tub of baking soda. You can also sprinkle the baking soda directly onto the items and brush it off.
Brighten your smile
Baking soda is a common ingredient in toothpaste, but you can give your teeth a little boost by scrubbing them with a paste of baking soda and water between brushings. Baking soda is just abrasive enough to scrape off coffee, wine and other yellowing substances before they penetrate your teeth.
Remove oil, grease and wine stains
Sometimes, scrubbing a stain just makes it worse. Let baking soda do most of the work. Sprinkle it on, let it sit and it will lift much of the offending substance from the surface. Brush it off and then rub the area with a paste of baking soda and water if necessary. This baking soda cleaning trick will remove oil stains from certain fabrics, and can save carpets and couches from permanent splotches of spilled red wine.
Polish silver, chrome and stainless steel
You don’t need a special polish for every surface in your home. A damp cloth dipped in baking soda makes chrome and stainless steel shine; add a little lemon juice to brighten brass. Real Simple notes that baking soda will even take the tarnish off silver: place the items on a piece of aluminum foil in the bottom of a pot and add a solution of 1/4 cup baking soda, 3 teaspoons of salt and a quart of boiling water. Cover the pot for a few seconds, and the ensuing chemical reaction will do all the work.
