How To Clean a Copper Range Hood

Copper is a favorite metal for custom range hoods because it comes in incredibly stunning designs. It is durable and relatively easy to maintain which is a sought-after benefit in range hoods. Most copper hoods have smooth surfaces that are nonporous and are non-stick meaning they remain clean much longer. However, it is common to find a poorly maintained copper range hood that is caked with grease. This can be unsightly if you have your range hood as the focal design point in your kitchen like with a canopy copper range hood.

To avoid such an embarrassing sight we have explained in great detail how to ensure your range hood retains its shine.

How To Clean the Exterior of Your Copper Range Hood.

Most copper range hoods that lack a paint or powder coating are frequently subjected to air and water which is often not ideal for the copper. This exposure results in the copper surface forming a natural patina coat that gives the hood a greenish hue. This is because copper goes through oxidation, which forms the patina coat that helps prevent further corrosion. To avoid this and ensure your copper vent hood retains its original color then you should clean it regularly.

Please ensure you turn off and unplug your copper range hood before you begin the cleaning.

What you'll need:

  • Warm water
  • Dish soap
  • Baking soda
  • White vinegar
  • Microfiber cloths
  • Soft-bristled brush/ Wet sponge
  • Rubber gloves
  • Lint-free flannel cloth
  • Copper polish

Most copper range hoods come with different finishes for their exterior, but for regular grease and dust maintenance, you can generally clean them with these steps:

Step 1:Remove any loose debris, such as dust or grease, from the hood with a soft-bristled brush.

Step 2: Create a cleaning solution by mixing warm water and a few drops of dish soap in a bucket. Dip a microfiber cloth into the cleaning solution and wring out the excess water.

Step 3: Use the damp cloth to wipe down the surface of the copper range hood. Ensure you clean the top, sides, and front of the hood. Be sure to clean any crevices or hard-to-reach areas.

Step 4: Rinse the cloth frequently in clean water and continue wiping until the hood is clean.

Step 5:Mix baking soda and warm water to make a paste. Apply it to any areas of the hood with tough stains or buildup. The paste will act as a soft abrasive to remove tougher stains. Use a soft-bristled brush or wet sponge to scrub the paste into the hood gently.

Step 6: Rinse the paste off with warm water and dry the hood with a clean soft cloth.

Step 7: Buff the exterior by applying copper polish to the dry copper hood surface with a lint-free flannel cloth.

  1. Remove the filter from the hood.
  2. Fill the container with hot soapy water.
  3. Add a tablespoon of baking soda to help loosen the grease, oil, or grimy particles on the filter.
  4. Place the filter in the container and allow the filter to soak for a minimum of 10 minutes.
  5. Scrub the filter thoroughly with the brush to release any grime still on it.
  6. Rinse and let the filter dry.
  7. Return the filter to its compartment after cleaning it with a clean cloth.

Cleaning the vents

These are the materials and steps required to clean it.

Materials:screwdriver, gloves, long scrub brush, spray-on copper cleaner, kitchen towel.


  1. Carefully detach the internal duct from the range hood.
  2. Spray the inside of the duct with the cleaner, and let it soak for at least 5 minutes.

  4. Rinse with hot soapy water and then with clear water.
  5. Allow the duct to dry.

Cleaning the fans and motor.

Fans and motors typically don't require extensive cleaning as they are not frequently exposed to vented air. Although they can accumulate dust, a simple wipe-down with a dry cloth or a few passes of a portable vacuum cleaner should be enough. Additionally, a qualified technician can regularly inspect and maintain the motor.
