Remove the filter from the hood. The method for detaching the hood range filter may be different depending on the type and model, but they are all fairly simple. Some are attached with screws, while others have a simple latch mechanism that you need to press and lift to remove. Certain filters have a fastener that you can rotate in and out of position. Figure out how your filter is attached, and remove it prior to cleaning.
If there is a plastic casing that covers your filter, you’ll need to remove that first using a screwdriver before you remove the filter.
Fill your sink with hot or boiling water. Make sure you use a sink stopper so the water doesn’t go down the drain. Use hot water only, making sure it gets as hot as possible. Fill the sink up about ¾ of the way.
If your tap water doesn’t get hot enough, boil water in a tea kettle or pot and then pour it in the sink.
Pour 1/4 cup (60 g) of baking soda and a squirt of dish soap into the sink. Measure about 1/4 cup (60 g) of baking soda and pour it in. Then, add about 1 tablespoon (15 mL) of degreasing dish soap. Mix the ingredients together until the water is soapy.
Use a brush to mix the baking soda mixture, especially if you used boiling water, to avoid burning your hands.
Add 1⁄4 cup (59 mL) of vinegar to the mixture for extra cleaning power.
Put the filter in the sink and let it soak for 10 minutes. If possible, make sure it is fully submerged so that the entire filter gets cleaned at once. Let the filter soak in the hot water for at least 10 minutes to allow the baking soda and dish soap to penetrate tough stains.
If your filter is on the larger side and doesn’t completely fit in the sink, you might need to do one half of your filter at a time.
