- Soak filter in a degreaser, rinse then try washing in the dishwasher. If it’s stainless steel, it should wash up with regular dishwasher detergent no problem.
- If it’s aluminum, be aware that dishwasher detergent can cause discoloration or pitting. You can try running it through a cycle without regular dishwasher detergent. I personally don’t worry about it, but it’s something you should be aware of.
For both inside and outside the hood, apply degreaser to a damp cloth and wipe down. Make sure not to spray any cleaner directly on the appliance since you could accidentally spray some into the exhaust fan motor or light fixture.
If the buildup inside the hood is especially thick, first make a thick paste of baking soda and water. Take a cloth wet with hot, soapy water and then scrub with the paste in a circular motion–wipe off as much as the grease as you can then rinse the cloth in a bucket of hot, soapy water. Reapply baking soda paste on the cloth and repeat as needed.
Once the majority of buildup has been removed–wash the unit with hot, soapy water to remove all traces of the baking soda paste and then clean with degreaser if needed.
