If the odor under your kitchen sink smells like garbage, the first thing you should do is clean the sink thoroughly. Use a mild detergent and warm water to scrub the sink basin and faucet. Be sure to also clean the area around the sink, including the drain and garbage disposal. This will help to remove any built-up food particles or residue that may be causing the unpleasant smell. After cleaning, rinse the sink with hot water and dry with a clean towel.1. Clean the Sink

To clean the disposal, run cold water and then turn it on while pouring a mixture of equal parts white vinegar and baking soda down the drain. Let the mixture sit for a few minutes before turning off the disposal and rinsing with hot water.2. Check the Garbage Disposal
The drain under your kitchen sink may also be the culprit of the unpleasant smell. Use a flashlight to inspect the drain for any clogs or debris. If you notice anything blocking the drain, use a pair of gloves to remove it. You can also try pouring boiling hot water down the drain to help break up any built-up grease or food particles.3.
