The most important thing is that you should clean the kitchen exhaust fan every once in a while. Kitchen exhaust fans do a great job of removing steam and smells from the kitchen when you are cooking. Cooking produces steam and grease, both of which can be drawn up through an exhaust fan above.
Cleaning kitchen exhaust has nothing special or complicate.
Tools and Materials:
Bucket; rubber gloves; breathing mask; scrub brush; paper towels; rags; ammonia; baking soda; trisodium phosphate cleaner (TSP); boiling water.
2. Open the kitchen window to ventilate the area where you’re working.
3. Gently remove covers and dissemble other possible parts including filters. Do not force any parts because you break them. Put them in the kitchen sink.
4. Soak them in a mixture of hot water and ammonia (1/2 cup ammonia to 1 gallon of water) for an hour.
5. Then, remove the filter and any parts from the liquid and scrub them.
6. Soak them again in hot water and scrub them clean before leaving them to dry.
7. Cleaning the Fan:
Scrub the exhaust fan blades. Do not use a hard brush because your kitchen exhaust fan will be scratched.
If the kitchen exhaust fan hasn’t been cleaned in a while, you’ll need to repeat this process several times in order to get rid of all the grease.
Keep drying the areas you’ve completed with paper towels.
8. Wipe area all the time with a damp rag.
9. Using paper towels, wipe down the motor housing unit.
11. Plug and turn on the fan.
Note: To keep the kitchen exhaust fan working properly you should give it a cleaning annually. Also, depends of how much you cook, you do need to clean the filters at least once every three months.
