How can I clean mold out of my microwave exhaust duct?

To clean mold out of your microwave exhaust duct, first, disconnect the microwave from the power source for safety. Remove the duct cover and use a mixture of warm water and mild detergent to scrub the affected areas with a brush or cloth. For stubborn mold, a solution of vinegar or a diluted bleach solution can be applied, but ensure good ventilation and wear gloves. Finally, rinse thoroughly and allow everything to dry completely before reassembling the duct.
