Range hoods use a filter to collect pollutants that naturally occur while cooking, including steam, smoke and grease. Daily use of the range will cause an abundance of dirt and grease that may become caked on to the range hood. This dirt and grease can cause an unsightly and unsanitary kitchen environment. Cleaning range hoods is a relatively easy process. However, to keep the build-up of grease to a minimum, regularly wipe the range hood with a damp, soapy cloth.

Things You'll Need

  • Bucket
  • Degreaser
  • Cloths
  • Mild dishwashing liquid
  • Rubber gloves
  • Baking soda
  • Ammonia

Cleaning the Filter

Remove the filter from the range hood.

Fill a sink or bucket with degreaser.

Soak the filter in the degreaser for about 30 minutes.

Wipe the filter with a cloth saturated in the degreaser.

Rinse the filter with cool water.

Wash stainless steel filters in a mixture of water and mild dishwashing liquid. Rinse and dry with a towel.

Discard charcoal filters and replace when needed. Do not clean charcoal filters.

Cleaning the Hood

Turn power off to the range. Put on some rubber gloves.

Scrape off as much of the grease as possible using a plastic or wooden spatula.

Apply a generous amount of commercial-grade degreaser to a damp cloth. Do not spray the degreaser directly onto the hood as you may accidentally spray the cleaner onto the exhaust fan motor or light fixture.

Scrub both the inside and outside of the range hood with the cloth.

Create a paste of water and baking soda and apply it to the range hood to remove tough, built-on grease.

Dampen a cloth with hot, soapy water and scrub the paste into the hood.

Rinse the hood with a clean cloth and hot water to remove the baking soda residue.

Tips & Warnings

  • Alternatively, use a mixture of ammonia and water. Wipe the range hood down with a cloth or sponge saturated in the mixture. Rinse with a damp cloth and allow it to air dry.
