Easy and Affordable Ways to Clean Your Garbage Disposal
The job of a garbage disposal is to shred food into small particles that can easily pass through your home’s plumbing lines. With so many different types of food particles going down the drain, the sink may occasionally develop a foul odor.

Before running to your local home improvement store to purchase a harsh cleaner to pour down the drain, try the following easy and cheap deodorizing techniques:
  1. Use citrus peels. Use the peel of an orange, lemon, or lime in your garbage disposal to give it a clean, fresh smell. Cut the peel into small bits, place it into the disposal and turn the disposal on. Within a few seconds, you should notice a much better smell. Rinse the peel particles away with hot water.
  2. Use a combination of ice and rock salt. Make a mixture of two cups of ice and one cup of rock salt. Pour the mixture down the drain then run cold water in the sink for ten to fifteen seconds. This should help to clear away some of the food particles which are creating the bad odors.
  3. Use white vinegar ice cubes. Take an old ice cube tray and fill it with white vinegar. Place the tray in the freezer for an hour or two. Once the cubes are solid, place a few down the disposal and turn it on. This will clean and deodorize the disposal. You can also try this method along with cut citrus peels.
  4. Use mouthwash. Fill a cup with mouthwash and slowly pour it down the sink drain. You will quickly notice a much better smell in your kitchen within seconds.
  5. Use baking soda with warm water. Take a tablespoon of baking soda and pour it down the drain. Follow it with half a cup of warm water. After a few minutes, pour half a cup of white vinegar down the drain. Let the mixture sit in the drain for a few minutes before running the faucet.
  6. Use borax and hot water. Pour three tablespoons of borax powder down the disposal and let it sit for twenty minutes. Afterward, let hot water run down the disposal.

If you still notice a foul odor coming from the drain after you try the above-mentioned cleaning techniques, you may need to call in a plumber.
