Pour it down the drain, let it sit for a few minutes, and then run hot water to flush it out.How to Get Rid of a Sewer Smell in the Kitchen | Hunker
If your kitchen sink still smells like sewage after cleaning the drains, there may be a more serious plumbing issue at play. One possible cause is a cracked or broken sewer line. This can allow sewer gas to escape and create a foul smell in your kitchen. Another common cause is a dry P-trap. This is the U-shaped pipe under your sink that traps water to prevent sewer gas from entering your home. If the water in the P-trap evaporates, it can allow the smell to seep into your kitchen. Make sure to run water in your sink regularly to keep the P-trap full.Why Does My Kitchen Sink Smell Like Sewage? | 5 Common Causes
