How do I maintain a kitchen hood?

To prolong the life of your range hood and maintain its efficiency, the appliance must be maintained regularly. Here we reveal the secrets of a good hood cleaning. We also offer a few practical tips to make the operation easier.

Maintenance of the body

Cleaning procedures begin with the maintenance of the body of the range hood. To do this, the operation consists of two steps, namely degreasing and actual cleaning. Before starting the procedures, first disassemble your hood.


Grease stuck to the body of the hood will cause it to yellow. To remove this material, first moisten a cloth with warm water. You can use a degreasing agent to simplify cleaning. Otherwise, use household alcohol or white vinegar. It is strongly recommended not to use industrial products to clean your fume hood at home.


The second step is to clean the body of the hood. If it is a stainless steel hood, use beeswax and a very soft cloth to perform the operation. In this way, the appliance will regain its shine. It is possible to use edible oil. Remember to maintain it regularly, i.e. every 2 days after use.

Cleaning the filters

The cleaning steps continue this time with the filters. The operations remain the same: degreasing and cleaning.

The degreasing of the filters

The maintenance of an extractor hood continues with the degreasing of the filters. Before the operation, remove the filters from their holders. Then go around the metal structure and unclip the assembly. Continue by immersing the filters in a bath of hot water foamed with dishwashing liquid. Wait a few moments before brushing. Rinse them with clear water at high pressure. Finally, drain them until they are completely dry. The maintenance of a professional kitchen hood is carried out weekly. If it is a domestic hood, maintenance is required every 6 to 8 weeks.

Cleaning and refitting

The cleaning of the filters continues with a good wipe with a damp cloth. To refurbish them, use vinegar. Go around the structure. If some foul odours persist, trade the vinegar for beeswax. Continue the operation by using an anti-tracking cloth on the entire metal structure to give it more shine. Finally, reassemble the filters.

Engine maintenance

The maintenance steps of a fume hood continue with the engine. This last operation is the most complex because of the multiple elements that make up the motor.

Dismantling the filters

To begin this last step, disassemble the engine. This component consists of the odor filter and the grease filter. To do this, remove the odour filter, also known as the carbon filter. The carbon filter cannot be cleaned, as it must be replaced if worn. The grease filter can be cleaned. You can wash it in your dishwasher. Then remove the motor defects and the central nut to access the turbine. If the turbine is made of plastic, clean it with a damp cloth, soap and water. If it is made of metal, use acetone instead of water.

Dislodging and cleaning the motor

For simple cleaning of the motor housing, simply spray pressurized air. If you wish to carry out a thorough cleaning, first dislodge the engine. Disconnect the cables and remove accumulated dust. Finish by reconnecting the wires. The maintenance operation of the motor of an extractor hood must be carried out with care to avoid damaging it. In case of doubt, seek the services of a professional for maintenance.

Maintaining a range hood

An extractor hood, whether for professional or domestic use, requires maintenance. The risks are considerable if this operation is delayed.
