The first step to removing sewer smell from your kitchen sink is to clean the drain. Over time, debris, food particles, and other substances can build up in the drain, leading to a foul odor. You can use a drain brush or a mixture of hot water and dish soap to scrub the inside of the drain and remove any buildup.1. Clean the drain
Baking soda and vinegar are a powerful combination when it comes to removing odors and unclogging drains. Start by pouring a cup of baking soda down the drain, followed by a cup of vinegar. Let the mixture sit for about 30 minutes, then flush it out with hot water. This will help break down any buildup and eliminate any odors.2. Use baking soda and vinegar
If the baking soda and vinegar method doesn't work, you can try using a commercial drain cleaner. Look for one that specifically targets odor-causing bacteria. Be sure to follow the instructions carefully and use caution when working with these chemicals.3. Use a commercial drain cleaner
The P-trap is a U-shaped pipe located under your sink that is designed to prevent sewer gas from entering your home. However, debris and buildup can get trapped in this pipe, leading to a foul smell. To check for clogs, place a bucket under the P-trap and unscrew the pipe. Clean out any debris and reattach the pipe.4. Check for clogs in the P-trap
If the smell is coming from a clog further down the drain, you can try using a plunger. Fill the sink with enough water to cover the plunger, then place the plunger over the drain and plunge vigorously. This can help dislodge any clogs and get rid of any trapped odors.5. Use a plunger
If the plunger doesn't work, you can try using a plumbing snake to remove any stubborn clogs. Insert the snake into the drain and turn it clockwise to break up and remove any debris. Be sure to wear gloves and use caution when handling the plumbing snake.6. Use a plumbing snake
