Kitchen extractor hoods usually get greasy very easily so cleaning experts strongly recommend you to implement a regular maintenance routine that will prevent the grease from building up even if it is a simple wipe off with a cloth and a degreaser once a week. However, if you want to set a high standard of hygiene and cleanliness at home and make sure that your kitchen absorber will function properly for a long time, a couple of thorough cleaning and disinfecting treatments a week are much better.
The grease filter itself needs to be cleaned and disinfected monthly. You can do that by simply unplugging the kitchen extractor first. Remove the screen mesh using a screwdriver or your index finger to slide it out. Make sure you are careful when doing that, otherwise, dirt and grease can fall out of the mesh. Next, soak the screen mesh in a basin full of hot water to melt away any oil and grime. Add half a cup of liquid kitchen detergent and let it soak for half an hour. Put on some rubber gloves and brush off the screen on both sides with a steel brush.
Finally, rinse off the screen with hot water. For heavy and stubborn grease and dirt, you may need to apply a stove or oven cleaner to help you remove the remaining grime and residue. Use a fume-free product or wear a protective mask and open the windows for proper ventilation. After spraying, let the product stay for an hour and afterwards remove the dirt with a steel brush or sponge. Rinse it off with hot water and dry it with a towel. Metal and stainless-steel filters are also dishwasher-friendly but those made out of aluminium may be discoloured by the washing detergent. Disposable filters are easy to replace and save on cleaning effort and time.
Do not forget to wash the fan blades by mixing ½ cup ammonia with 1 gallon of warm water and scrubbing any dirt from the fan with this mixture. Wipe off excess grime and dust with a damp cloth. Wash both the interior and exterior of the main kitchen extractor hood body with a citrus degreaser and a cloth. For stubborn and hard to remove grease and dirt you can use a mixture of baking soda and water with the consistency of a paste. Apply the mixture with a help of an old toothbrush or any other kind of brush with soft bristles and scrub thoroughly every nook and corner. Allow the unit to dry completely, then place the screen back into the unit and plug it in.
Making sure you are following the above-described method will help you enjoy a completely sparkling clean and well-disinfected kitchen appliance that functions properly and will serve you in a long term.
