If you peek under your stove's hood and check the exhaust fan filters, you might find that it's not pretty. That's because a range hood filter is supposed to collect grease.
The filter can get so gunked up over time that it loses its effectiveness, which is why we recommend periodically de-greasing them. Get ready to roll up your sleeves.
Your range hood cleanliness begins with dusting to eliminate particles from the surface. We recommend using a dust brush cleaner with a brush that is able to get to delicate and hard-to-reach places. Before doing this, cover the stove with a cloth so that dirt and debris don't fall inside. Let’s move on to cleaning the filters.
The first step is to remove filters from the hood. Most filters easily slide or pop out of the underside of the hood.
Let the filters soak in a sink or tub with hot or boiling water and a generous squirt of dish soap. Baking soda can also help. Swish around with a brush until the water is soapy and make sure the filters are fully submerged.
Once the filters have soaked for 15-20 minutes, use a non-abrasive scrub brush to scrub the filters, adding more dish soap if necessary. Simply rinse the filters in hot water, dry, re-insert the filters back into the hood, and repeat periodically. Cleaning the filters once a month is a general rule of thumb.
