Summarize the following:
Both baking soda and dish soap help grease dissolve in water. Combining both ingredients creates a non-toxic cleaning solution that quickly and effectively breaks down tough grease build-up. Adding the baking soda slowly, to cool water, will prevent it from fizzing up over the top of your pot. The hot water will help loosen the grease, allowing the cleaning solution to fully penetrate into the filter. Remove the water from the heat as soon as it starts to boil; too much agitation will create bubbles from the dish soap, which can spill over onto your stove. You can use this cleaning solution to remove grease from the exhaust hood and fan blades inside your unit. Extra solution can also be used to easily clean your stove-top and oven. Pour the solution slowly to prevent backsplash. Keep adding solution until the grease filter is completely submerged. Keep  any extra solution warm, in case an additional soak is needed for a filter with particularly serious grease  build-up.  You can soak the filter in the same pot you heated the solution, as long as it is not a non-stick pot. The metal filter will scratch non-stick coating. Most pots are not big enough to completely cover a typical grease filter, so you may need to do half of the filter at a time in order to get the entire filter clean. As the filter soaks, the baking soda and dish soap will slowly dissolve the grease. The dirtier the filter, the longer you should let it soak. If you have not cleaned your filter in years, you may need to let it soak for up to an hour. Use a non-abrasive sponge or soft bristled  brush to scrub away any remaining grease. The grease should come away easily. Avoid scrubbing aggressively to minimize the risk of damaging your filter. If some of the grease is stuck on the filter, repeat the soaking process with clean solution. Wash away as much grease and residue as possible. Grease will collect faster on areas of the filter that are still dirty. Starting with a perfectly clean filter will slow down future build-up. You do not want any moisture on your filter when you re-install it. Air-drying, instead of using a cloth or blow drying, will prevent the filter from being damaged. The filter should be completely dry after an hour or 2 of air-drying. The more you cook, the more often you should clean your grease filters. Regular cleaning will make your exhaust fan operate much more efficiently, and greatly decrease the health and safety risks that grease build-up presents.

Summary:
Slowly add baking soda and dish soap into a large pot of water. Bring the water to a boil. Set aside 1 cup (235 ml) of the finished cleaning solution. Carefully pour hot cleaning solution over the grease filter. Let the filter soak for 15-30 minutes. Scrub away the grease. Rinse the filter off with hot water. Air-dry your filter completely. Clean your grease filters regularly.
