How to Clean a Kitchen Range Hood Filter

How to Clean a Range Hood Filter

1. Remove the Filter

   To remove a reusable filter, either slide it out or find the latch you use to pop it out.

2. Prepare the Cleaning Solution

   Fill a sink with boiling water. If the sink isn't available, use a large pot or glass baking dish that is heatproof. Add one to two tablespoons of dishwashing liquid to the water. Add one-half cup baking soda and mix the solution well. Be sure that the dishwashing soap label states that it contains a degreaser.

3. Soak the Filter

   Submerge the filter into the solution and let it soak for at least 15 minutes. No need to scrub now; let the cleaners do the heavy-lifting. If you get distracted, try to remove it before the water cools entirely and the grease resettles on the filter.

4. Scrub the Filter and Rinse

   Next, use the scrub brush to remove grease or food particles still clinging to the filter. Rinse well with hot water and dry thoroughly before placing back in the range hood.

How to Clean the Range Hood Surfaces

1. Apply the Degreaser

   Make sure the stovetop is clear of any utensils (you may get drips), and spray on the degreaser or a homemade vinegar solution. Allow it to work for at least 15 minutes.

2. Wipe Away Degreaser

   Use paper towels to wipe away the cleaner and the grime. If any particles are left, spritz a bit of degreaser on a nylon-bristled brush and scrub those areas. Finish by wiping away any remaining residue.

3. Rinse Well

   Finally, dip a clean paper towel or cloth in warm water and rinse the interior to remove any remaining cleaner.

Tips to Keep a Kitchen Range Hood Clean Longer

Every type of range hood has a filter that fits over the fan and helps catch grease and food before entering the ductwork. Most are metal that can be cleaned and reused for many years, while some are disposable charcoal filters. Cleaning the filter is the easiest part of the job and doesn't require harsh chemicals. Check the manufacturer instructions.

Cleaning the exterior surface depends on the type of material used for the hood. Most under-the-cabinet hoods or mounted microwaves with a vent are either stainless steel or painted metal. Use a degreasing cleaning product recommended for those finishes and a soft cloth to remove the grease. To prevent streaks on stainless steel, use a drop or two of olive oil on a microfiber cloth for a final polish.

Large decorative hoods should be dusted weekly and cleaned monthly to maintain beauty. Copper and brass metal hoods can be highly polished or allowed to develop an aged patina. Follow the builder or manufacturer's guidelines for different types of finishes.

How to Clean Interior or Exterior of Hood With a Homemade Degreaser Solution

You can remedy grease buildup on the hood with a commercial degreaser, a rag soaked with undiluted vinegar, or a spray of half vinegar and half water solution. Vinegar is composed of 95% water and 5% acetic acid. This mild acid is strong enough to cut through grease and has no harsh fumes or chemicals. It doesn't smell nice at first, but the scent dissipates after a few minutes.

When to Call a Professional

If the vent fan is not working—and you have no idea why—it's time to call a repair professional. Before you make the call, try to clean the interior parts, including the motor and fan, and if you notice the ventilation is not working, or a loud sound lingers, the fan may be malfunctioning. The motor might need to be cleaned to prevent rubbing or grinding.

If a motor needs replacement, it can cost about $100 to replace. However, if the whole assembly needs replacement, it can average about $500—more or less, depending on the model and your region.

Another indicator that you need to call a repair professional is if the lights or buttons are not working. It can be an electrical wiring problem requiring an electrician or service professional to diagnose and fix it.
