Wipe down your cooking range hood daily to prevent grease buildup.

It's easy to overlook and neglect the hood over your cooking range while cleaning, until you happen to glance up and notice the layer of caked-on grease that's been accumulating for months. The hood's grease filter is typically even worse. It's nothing that you can't handle, however, with household cleaning products that are effective at cutting through grease.

Hood Exterior

Soak a cotton rag with dish soap and hot water and scrub the cooking range hood vigorously. Liquid dish soap easily cuts through grease. Look for dish soap with labels like "tough on grease" for the best results. Wipe the hood dry with a clean, dry rag.

Remove stubborn grease by dipping the wet cotton rag in a little baking soda and scrubbing vigorously. Dissolving grease is one of the many capabilities of baking soda. Wipe down with clean water and dry.

Use a solution of equal parts ammonia and hot water to remove extra tough grease stuck on the hood. Allow the mixture to sit for a few minutes to allow the ammonia to work before rinsing off and wiping the hood dry.

Cleaning the Filter

Remove the filter screen from the hood. You may need to release or unhook latches to remove it, depending the type of oven hood you have.

Fill your sink or a large basin with hot, soapy water and place the filter in it to soak. Add a couple tablespoons of baking soda for extra grease-cutting power. Let it sit in the water for up to 30 minutes.

Scrub the filter with a non abrasive brush to remove oil and food articles. Repeat the soaking with fresh hot water and soap, if necessary

Rinse and dry thoroughly, then replace your clean filter in the appropriate spot above your cooking range.

Items you will need

  • Cotton rag
  • Dish soap
  • Baking soda
  • Ammonia
  • Hot water


  • You can also spray the filter with oven cleaner and allow it to sit for a few minutes before scrubbing to help remove well-lodged dirt and stubborn grease.
  • Try adding auto degreaser, which you can purchase from any auto parts store, to the hot soapy water for an extremely greasy filter.


  • Ammonia fumes can be toxic if inhaled, and ammonia can be corrosive to the skin, even when diluted in water. Open the windows and air vents in the area you are using it and wear rubber or latex gloves and a long-sleeved shirt to protect your skin. If you do get ammonia on your skin, flush the area with water for 15 minutes. Seek medical attention if the irritation continues or you get any in your eyes.
