## Why Does Underneath My Kitchen Sink Smell?
The kitchen sink is one of the most used areas in the home, and as a result, it can often accumulate a lot of dirt and grime. This can lead to a build-up of bacteria, which can cause a nasty smell. Here are some of the most common reasons why underneath your kitchen sink may smell:
### Garbage Disposal
One of the most common causes of a smelly kitchen sink is a garbage disposal that is not properly cleaned. Food particles can get stuck in the disposal, and over time, they can start to rot and smell. To clean your garbage disposal, simply run some cold water down the drain and then add a few tablespoons of baking soda. Let the baking soda sit for a few minutes, and then turn on the disposal and let it run for a minute or two. This should help to remove any food particles that are stuck in the disposal and eliminate the smell.
### Drain Trap
The drain trap is a U-shaped pipe that is located under the sink. It is designed to trap water and prevent sewer gases from escaping into the home. However, if the drain trap becomes clogged, it can allow sewer gases to escape, which can cause a nasty smell. To clean the drain trap, simply remove the clean-out plug and pour a cup of vinegar down the drain. Let the vinegar sit for a few minutes, and then flush the drain with hot water.
### Leaky Pipes
Leaking pipes can also be a cause of a smelly kitchen sink. If a pipe is leaking, it can allow water to seep into the cabinet under the sink, which can create a breeding ground for bacteria. To check for leaks, simply look for any wet spots under the sink. If you find any, you should contact a plumber to have the leak repaired.
### Mold and Mildew
Mold and mildew can also cause a nasty smell under the kitchen sink. Mold and mildew thrive in damp, dark environments, so they can often be found in areas that are not properly ventilated. To prevent mold and mildew from growing, make sure to keep the area under the sink dry and well-ventilated. You can also use a dehumidifier to help remove excess moisture from the air.
### Other Causes
In some cases, the smell under your kitchen sink may be caused by something other than the above. For example, the smell may be coming from a dead mouse or rat, or it may be caused by a chemical spill. If you are unable to identify the source of the smell, you should contact a professional for help.
