Garbage Pails and Disposals
Keep your kitchen garbage pail smelling fresher by sprinkling a bit of baking soda in the bottom each time you empty it. Every now and then, wash and deodorize the can with a solution of baking soda in warm water.
It's also a good idea to give your garbage disposal the royal treatment every month or so. Pour 1/4 cup each salt, baking soda, and dishwasher detergent into the disposal, turn on the hot water, and run the disposal. Doing this should clean out the gunk and get rid of lingering odors. You can also drop the rind from a citrus fruit such as a lemon, lime, or grapefruit down the disposal. Grind away -- the rind helps to clean the disposal's "teeth" and gives a fresh scent to your kitchen.
