1. Boiling water and baking soda
Using a large stainless steel pot (ensure it is not non-stick) bring a large amount of water to the boil. Once bubbling, slowly add baking soda a teaspoon at a time until the water starts to fizz. Once fizzing, using a pair of steel tongs to hold the filter, dip one end of the vent into the water (or the whole filter, depending on how big it is) for 60 seconds. Repeat on the other end. The grease should now have melted off the filter and collected in the water. Et voila! Clean filters!
2. Use a steam cleaner
For those who have a steam cleaner at home, this is a relatively quick and painless way of removing grease from your range hood filter. Lay the filter over some paper towel, and use a small nozzle of a steam cleaner to push the grease through the filter to collect on the paper towel below.
3. Bake it
Fill the bottom of a oven tray with newspaper cut to fit the inside of the tray. Lay the filter inside the tray, Pop it in the oven at 100 degrees Celsius for around half an hour. The grease should start to melt off the filter and fall onto the paper beneath. Once done, give it a quick wash with warm water and dish soap. All clean!
