  4. Ensure you spread the vinegar solution evenly over the polished exterior surface.
  5. Wipe down any excess solution.
  6. Allow it to settle and dry.

How to Care for The Interior of a Custom Range Hood

The interior of a custom range hood has all the electrical and mechanical components that enable it to clear the kitchen air. These parts are hidden from view and often require loosening some screws to access them. Before cleaning the inside, the range hood should always be turned off and unplugged from the power source.

For optimal range hood performance, these components must be frequently cleaned and maintained, as shown below:


  • Dish soap or degreaser
  • Warm water
  • Scrub brush or sponge
  • Paper towel
  • Soft cotton cloth
  • Lint-free rag
  • Baking soda or vinegar
  • Duct cleaning brush or vacuum with long hose attachment
  • Ductwork cleaning solution
  • Gloves
  • Protective eyewear
  • Dust mask
  • Screwdriver

How to clean the filters

How you take care of your range hood filter will depend greatly on what kind of filter it is. Follow the procedure below for a mesh or stainless steel baffle filter.

Step-by-step process:

  1. Turn off the range hood and disconnect the power source.
  2. Remove the filters from the hood. Consult the manufacturer's instructions for specific filter removal steps.
  3. Soak the filters in warm water mixed with dish soap or degreaser for 10-15 minutes. Add a tablespoon of baking soda or vinegar to the warm water for more stubborn grease buildup.
  4. Using a scrub brush or sponge, gently scrub the filters to remove any remaining grease or dirt.
  5. Rinse the filters with warm water to remove any soap or cleaning solution.

Why Proper Care of Custom Range Hoods is Important

Proper care of custom range hoods is important because neglecting to care for your range hood can lead to decreased efficiency. It can lead to an increased risk of damage or malfunction which often will require expensive repairs. Therefore, it is essential to understand the importance of proper care for your range hood. Some of the notable ones are:

  1. Regular maintenance of a custom range hood helps to extend its lifespan. Grease, dirt, and dust can accumulate on the surface of the range hood and this can cause corrosion. This leads to the deterioration of the range hood’s quality over time. You can prevent this from happening with proper care which keeps your range hood in good condition for longer.
  2.  By wiping down the exterior regularly, you can prevent the accumulation of grease and dust. If not cleaned these particles can find their way into the fillers and quickly clog them up. A blocked range hood will have restricted airflow. It can’t efficiently capture smoke, grease, and cooking odors. This will allow the pollutants to remain in the kitchen or spread to other areas of your home.
  3. A custom range hood that is not adequately maintained can be prone to damage and malfunction. This can result in costly repairs or even result in the need to get a replacement hood. Proper care and regular maintenance can prevent rust and other damage which ensures that it functions correctly.
  4. Custom range hoods tend to accumulate grease and oil on their filters, grease traps, and ductwork. Accumulated grease and oily particles can start a fire or even damage the internal components. This is especially true with an oven hood or custom hoods over gas stoves. Regular cleaning of the ductwork can help prevent the buildup of these impurities.

Tips for regular maintenance

Regular maintenance is crucial for keeping your custom range hood in good working condition. Here are some tips for regular maintenance of your range hood:

  1. Clean the exterior hood regularly because it tends to collect a lot of grease and dirt. This affects the range hood’s performance and forms odd colors on your unique custom range hood surface. Regular hood cleaning with warm soapy water or with a degreaser solution can prevent odd and unnatural patina from forming.
  2. Regularly clean the range hood insert and internal parts because they can easily accumulate grease and dust. This includes blowers (fans) and motors. Failure to do this can cause motor failure and reduce performance. Regular cleaning of the blower wheel and fan blade can keep the range hood in good condition. This can be done often with a damp cloth or a mild cleaning solution.
  3. Clean the ductwork because this is where grease, dust, and other debris often collect. if left unattended, this can reduce the range hood’s performance and can pose a fire hazard. Regular cleaning with a duct cleaning brush or a vacuum with a long hose attachment can prevent this buildup.
  4. Replace the filters because they collect grease and other particles and clog up frequently. This can affect the range hood’s performance and is often not a fire hazard. Replace the filters every six months to 1 year based on how you use your range hood.
  5. Regularly inspect the range hood and ductwork for any signs of damage or leaks. Replace or repair any damaged parts immediately. This prevents further damage and saves you larger repair costs down the line.
  6. Hire a professional for major maintenance and repairs because hiring a professional for more complex tasks is always advisable. A professional can ensure that the range hood is in good working condition. They can identify any potential issues that must be addressed that you might have missed.


Providing adequate maintenance and care for your custom range hood is very important. A regular maintenance schedule is advisable to streamline the process for you. This will ensure your range hood works optimally and reduce the cost you spend on repairs in the long run. Ensure you always check the owner’s manual for specific cleaning and maintenance recommendations. A poorly maintained range hood is a fire and health hazard.
