What are some common causes of a bad smell coming from the bathroom sink, and how can it be effectively eliminated?

Answer 1

Common causes of a bad smell from the bathroom sink include buildup of organic matter, mold, or bacteria in the drain. To eliminate the smell, you can try pouring a mixture of baking soda and vinegar down the drain, using a drain snake to remove any clogs, or using a commercial drain cleaner. Regularly cleaning the sink and drain can also help prevent odors from returning.
