kitchen hood cleaning frequency 2

How often should you clean your kitchen hood? Depends on how much you cook. Heavy daily use? Every three months for a deep clean. Light use? Twice a year might be enough. Grease buildup not only smells bad but can be a fire hazard. Also cleans better when grease isn't thick. Some filters can go in the dishwasher, others need scrubbing. Check the manual. For restaurants, it's a whole different story, but for home, listen to your nose and the grease feel.
