A hood is the hood or air outlet above the oven. Many of the kitchen vent hoods in kitchens today were produced in China. The bell is usually done with some sort of metal such as stainless steel, and can be achieved by coating all kinds of cooking grease. The screen on the inside of the hood is filled with grease and dust in some cases. Cleaning the hood will make your kitchen look better and allow ventilation to work best.
Fill a sink full of hot water and 3 tablespoons. Dishwashing soap. Remove the kitchen vent hoods screen inside the hood and place it in the sink. Rub the screen with soapy water and soak for 15-20 minutes. Fill the spray bottle filled with vinegar and spray on the outside of the bell. Let sit for two or three minutes.
The vinegar helps remove fat from the bell of Chinese cuisine. Dampen a clean cloth and vinegar bell. Rinse the kitchen vent hoods screen with clean warm water and sprinkle with vinegar to remove any remaining stuck-on grease. Rub the screen again and rinse again. Allow the screen to air dry. Replace the hood when it is dry.
