How can I get rid of a bad smell coming from my kitchen sink?

The first step to take is to identify the source of the odor. Once you have identified it, you can begin eliminating potential causes such as food scraps and grease buildup in your pipes or drains. You may also want to try using baking soda and vinegar to scrub out the drain and rinse with boiling water. If the smell persists, you may need to replace your plumbing fixtures or contact a plumber for further assistance.
