Product review (5 stars): Great Deal for Three... Clean the Silver Part Yourselves
I recently watched a video on You Tube that detailed a woman cleaning the hood filter on her stove (silver part).  First you fill a large pot with water and bring it to a boil on the stove. If your pot is large enough you can do this next part right on the stove, but mine was not, so I used my kitchen sink. I stopped up the sink, put the silver part of the filter inside the sink, and poured the boiled water onto it. Then I added one cup of baking soda. It will fizz up. Take a pair of gloves that are heat resistant or a pair of salad tongs and turn the filter over and over until you see the grease come off. You can use an old toothbrush to scrub it too. Repeat if you did not get all the grease off the first time... otherwise it shoud come out shiny like new. Rinse it off and let it dry overnight. I tried to clean the carbon by soaking it in a degreaser, but that did not work. So I was overjoyed when I saw a three pack for sale on Amazon.com. Most places want you to pay $22.00 for the hood filter with the charcoal attached. Once I cleaned the hood filter (silver part) all I needed were the charcoal replacements, so that was not an option for me. Thanks again Amazon!
