If you're experiencing a strong, unpleasant rotten egg smell coming from your kitchen sink drain, the first step is to clean the drain thoroughly. This smell is often caused by built-up food particles, grease, and other debris that have accumulated in the drain over time. To clean the drain, start by removing any visible debris from the opening of the drain. Next, pour a mixture of hot water and dish soap down the drain and let it sit for a few minutes before rinsing it with more hot water. This should help to eliminate any lingering odors and leave your drain smelling fresh and clean.1. Clean the drain

You can check for clogs by using a plunger or a drain snake to clear any blockages in the drain. If you're unable to remove the clog yourself, it's best to call a professional plumber to avoid causing any further damage to your pipes.2. Check for clogs
