How to Get Rid of Bathroom Sink Smell

A foul smell emanating from your bathroom sink can be a major annoyance. Not only does it make the space unpleasant, but it can also indicate underlying issues with your plumbing system. However, getting rid of bathroom sink smell is not a difficult task. With a few simple steps, you can eliminate the odor and enjoy a fresh-smelling bathroom once again.

1. Clean the sink drain: Start by removing any visible debris or hair clogs from the sink drain. Use a pair of gloves and a paper towel to pull out any gunk that may be causing the smell. Be sure to dispose of the debris properly.

2. Pour boiling water: Boiling water can help break down any organic matter that may be causing the smell. Carefully pour a pot of boiling water down the sink drain, ensuring it goes directly into the drain and not onto any surrounding surfaces.

3. Use baking soda and vinegar: Baking soda and vinegar are natural deodorizers and can help eliminate the odor. Start by pouring half a cup of baking soda down the drain. Follow it up with half a cup of vinegar. Let the mixture sit for a few minutes to allow it to fizz and break down any stubborn residue. Finally, rinse it down with hot water.

4. Clean the sink overflow: The overflow hole in the sink can also harbor bacteria and contribute to the smell. Use a small brush or toothbrush dipped in a mixture of baking soda and water to clean the overflow hole thoroughly. Rinse it with hot water afterward.

5. Flush with bleach: If the smell persists, you can use bleach as a last resort. Mix one part bleach with ten parts water and pour it down the drain. Let it sit for a few minutes before rinsing it away with hot water. Be cautious when using bleach, as it can be harmful to your skin and eyes.

6. Maintain good habits: Preventing future smells is as important as getting rid of the current one. Make sure you don’t let food scraps or hair go down the sink drain. Use a drain strainer or stopper to catch any debris. Regularly flush the drain with hot water to keep it clean and prevent buildup.
