A cast iron range hood is a durable feature that can enhance the look of a kitchen while keeping the air clean. Cleaning it regularly prevents grease build-up and keeps the appliance looking new. A simple maintenance routine can extend its life and improve its performance.
Daily Cleaning Routine
After each cooking session, wipe the exterior with a damp cloth and a mild detergent. Avoid harsh abrasives that can scratch the finish. Use a soft brush to remove any light grease from the grill area. Dry the surface with a clean towel to prevent water spots.
The fan blades should be checked for visible grease before the kitchen is turned off. If any residue is seen, use a small brush to clear it gently. Do not use high pressure water as it can damage the motor housing. Allow the hood to air dry fully before the next use.
Store a small container of baking soda near the hood for quick spot cleaning. Sprinkle it lightly over greasy patches and let it sit for a few minutes. Wipe away the residue with a damp cloth. This keeps the surface fresh without chemicals.
List of quick daily actions. Check for grease on the grill. Wipe the exterior with a damp cloth. Use baking soda for spots.
Weekly Deep Wash
Remove the grill and any removable panels carefully. Soak them in warm water with a gentle dish soap for a short period. Scrub the panels with a soft brush to lift stubborn grease. Rinse thoroughly and dry before reinstalling.
Clean the fan housing by removing any loose debris with a soft brush. Wipe the interior with a damp cloth and mild soap. Avoid using a wet rag that could leave water inside the motor compartment. Ensure all parts are completely dry before reassembly.
Apply a thin coat of a non-abrasive polish to the cast iron surface. Use a soft cloth to spread the polish evenly. Buff the surface to a subtle shine. This protects the metal from future oxidation.

Monthly Filter Care
Locate the grease filter beneath the hood and lift it gently. Rinse it under running tap water, using a soft brush to dislodge trapped grease. Avoid soaking the filter for extended periods as it can warp.
Dry the filter thoroughly with a clean towel before placing it back. Check for any cracks or tears that could reduce its effectiveness.
If the filter shows signs of wear, replace it with a new one. Store the spare filter in a dry place for future use.
Lift and rinse the filter. Dry and replace if damaged.
Seasonal Vent Inspection
Turn off the power supply at the switchboard before inspecting the vent.
