The answer to 'kitchen smells bad' is that there are several common causes, including spoiled food, grease buildup, mold or mildew, and poor ventilation. Symptoms may include a persistent unpleasant odor, even after cleaning. To address the issue, start by thoroughly cleaning the kitchen, including the sink, cabinets, and appliances. Use a degreasing cleaner and baking soda to remove stubborn grease and odors. If the smell persists, check for any signs of mold or mildew and address the source. Improving kitchen ventilation can also help prevent odors from building up.
If the smell is coming from a specific appliance or area of the kitchen, and basic cleaning doesn't resolve the issue, it may be best to call in a professional cleaning service. They can use specialized equipment and techniques to deep clean and deodorize the kitchen, identifying and addressing the root cause of the problem.
