How to Clean Kitchen Exhaust Fan Grease

Range hoods and vent hoods, commonly referred to as kitchen exhaust fans, are essential in the kitchen. They support the ventilation of cooking-related smoke, steam, and odors. These fans gather oil, dust, and other materials over time. A consistent cleaning schedule improves the longevity of the equipment and maintains the health of your kitchen. Here’s a comprehensive guide on how to clean kitchen exhaust fan grease.

Why is it crucial to clean kitchen exhaust fan grease?

Fire Safety: Grease is flammable. A thick layer of grease can be a potential fire hazard if it catches fire.

Longevity: Regular cleaning can prolong the life of your exhaust fan and save you money in the long run.

Health Reasons: Grease can become a breeding ground for bacteria and mold, potentially leading to health issues.

Gathering Materials

Before starting the cleaning process, gather all necessary materials:

  • Warm water
  • Mild dish soap
  • Baking soda
  • White vinegar
  • Soft cloths or sponges
  • A soft brush

Examine the Exhaust Fan Blades:

The kitchen exhaust fan is essential for keeping the space clean and fresh while you cook. While most individuals routinely clean or change the filters, they frequently forget to do the same with the fan blades. These blades build up layers of grease and dust over time, which can decrease the fan’s performance and increase the risk of a fire. Examine the exhaust fan blades carefully before starting to clean. Look for any evidence of wear and damage, accumulated grease, and filth. For instructions on how to reach and inspect the blades, consult the user handbook because the procedure may differ depending on the model.

Pay attention to the exhaust fan’s exterior while the filters are soaking. White vinegar and water mixed in equal amounts should be used to dampen a soft cloth or sponge. Make sure all grease and filth are removed by giving the fan’s exterior a good cleaning. Use a gentle brush to clean stubborn stains.

Scrubbing the Filters:

After soaking, use a brush to gently scrape the filters. Dish soap and baking soda should help to loosen the grease and make it simpler to remove. Make a thicker paste of baking soda and water, apply it to any stubborn spots, wait a few minutes, and then scrub the area once more.

The Science Behind Grease Build-up:

The majority of the triglycerides in the grease that collects in your kitchen exhaust fan come from cooking fats and oils. These fats become aerosolized while cooking, especially at high temperatures or during frying, and are then sucked up by the exhaust fan. As they come into touch with cooler surfaces over time, such as the filters and interior of your fan, they harden and build up.
