Baking soda... out of the cake and into the what???

Baking soda cleans, deodorizes, scours, polishes, removes stains, and softens fabrics. Use it on plastic, vinyl, carpeting, and upholstery, on silver and stainless steel, inside refrigerators or down drains.

Drain cleaner: Pour one cup down the drain followed by three cups of boiling water.
Chemical smells out of clothes: Soak clothes for two to three hours or overnight, in one cup of baking soda. Agitate the machine occasionally. Repeat if necessary. Wash as usual. (This method is great for removing the new smell out of clothes.)
Cat urine: Alternate sprinkling baking soda, which will neutralize acid odours, with white distilled vinegar.
Silver polish: Make a paste of baking soda and water, scoop some onto a clean, soft rag, and polish the silver. Rinse and polish dry.
Soft scrubber: Pour about 1/2 cup of baking soda into a bowl and add enough liquid soap or detergent to make a texture like frosting. Scoop onto a sponge and clean the bathtub or tiles. Rinse.
Scouring powder: Simply sprinkle baking soda into a sink and scrub.
Oven cleaner: Sprinkle baking soda onto the bottom of the oven. Squirt with enough water that the baking soda is damp. Let set overnight, making sure the baking soda is damp before you go to bed. In the morning, simply scoop the baking soda and grime out with a sponge. Rinse.
Refrigerator deodorizer: Place an open box in the back of the fridge. It will “adsorb” odours, which means that it will draw odours to the baking soda molecules.
Cutting board deodorizer: Sprinkle the cutting board with baking soda, scrub, rinse.
