Start by gathering essential materials: dish soap, baking soda, vinegar, and a garbage disposal. For natural deodorization, pour baking soda down the drain, followed by vinegar. Let it fizz and clear before rinsing. Run ice cubes through the disposal to sharpen its blades. Slice lemons and toss them into the disposal to freshen the scent. Commercial deodorizing products offer a quick solution. Follow the manufacturer’s instructions and pour the product into the disposal. Run water to flush and activate the deodorizing agents.
