How to Get Rid of Sink Smell

A foul odor emanating from your sink can be a frustrating and unpleasant problem to deal with. Not only does it make your kitchen or bathroom smell unpleasant, but it can also be a sign of underlying issues with your plumbing. Fortunately, there are several simple steps you can take to eliminate sink smell and keep your sink smelling fresh and clean.

1. Clean the drain: The first step in getting rid of sink smell is to clean the drain thoroughly. Remove any visible debris or hair from the drain using a pair of gloves and a drain snake or tweezers. Once the visible debris is cleared, pour a mixture of baking soda and vinegar down the drain. Let it sit for about 30 minutes, then flush it with hot water.

2. Use a natural cleaner: If the odor persists, you can create a natural cleaner using ingredients you likely already have at home. Mix equal parts of baking soda and lemon juice to form a paste. Apply the paste to the inside of the sink and let it sit for a few minutes before rinsing it off with water. Lemon juice acts as a natural deodorizer, leaving your sink smelling fresh.

3. Flush with boiling water: Boiling water is a simple yet effective way to eliminate sink odor caused by accumulated grease or food particles. Carefully pour boiling water down the drain, making sure not to splash yourself. The hot water will help dissolve and flush away any leftover residue that may be causing the unpleasant smell.

4. Check the P-trap: The P-trap is a curved pipe located under the sink that traps water to prevent sewer gas from entering your home. If the odor persists even after cleaning the drain, the P-trap might be the culprit. Place a bucket or basin underneath the P-trap, then unscrew the pipe and remove any debris or buildup. Clean the P-trap thoroughly and reinstall it.

5. Use a commercial drain cleaner: In some cases, a stubborn sink smell may require the use of a commercial drain cleaner. Choose a product that is specifically designed to eliminate odors and follow the instructions carefully. Be cautious when using chemical cleaners, as they can be harmful if not handled properly. Remember to always wear gloves and avoid inhaling the fumes.

7. Seek professional help: If you have tried all the above methods and the sink smell persists, it may be time to seek professional help.
