If you notice a bad smell coming from your kitchen sink, the first thing you should do is clean the sink drain. Over time, food particles, grease, and other debris can build up in the drain, causing the unpleasant odor. To clean the drain, use a solution of hot water and baking soda. Pour a cup of baking soda down the drain, followed by a cup of hot water. Let it sit for a few minutes, then rinse it out with more hot water.1. Clean the sink drain
If the baking soda and hot water solution doesn't completely eliminate the smell, try adding vinegar to the mix. The combination of baking soda and vinegar creates a chemical reaction that can help break down and dissolve any buildup in the drain. Pour a cup of vinegar down the drain, followed by a cup of hot water. Let it sit for a few minutes, then rinse it out with more hot water.2. Use baking soda and vinegar
In some cases, the bad smell may be caused by a clogged drain. Use a plunger to try and dislodge any clogs. Place the plunger over the drain and pump it up and down several times. This will create suction and hopefully dislodge any debris or buildup that may be causing the odor.3. Check for clogs
If the plunger doesn't work, you may need to use a drain snake. This tool is designed to reach deep into the drain and remove any clogs. Insert the drain snake into the drain and turn it clockwise while pushing it down. This will help to break up and remove any debris that may be causing the bad smell.4. Use a plunger
If the plunger and drain snake don't work, you may need to use a commercial drain cleaner. These products are specially formulated to break down and dissolve any buildup in the drain. Follow the instructions on the product carefully and use gloves and eye protection when handling these chemicals.5. Use a drain snake
