Step 7 · Clean and Deodorize the Disposal

As a final step to ensure the disposal is clean and running well, you can clean and deodorize it. Turn off the disposal but keep the water running for a moment. Then, turn off the water and place a stopper in the sink. Pour about a half cup of baking soda into the disposal, followed by one cup of white vinegar. It will fizz and bubble. Let it sit for 10-15 minutes. Remove the stopper, turn on the cold water, and then turn on the disposal to flush it all out. For extra cleaning and sharpening, you can then grind a few trays of ice cubes. For a fresh scent, grind up a few citrus peels (lemon, lime, or orange).
