**Understanding Your Kitchen Exhaust Fan**

Before diving into the cleaning process, it’s essential to understand your kitchen exhaust fan’s components. Typically, an exhaust fan includes a hood, filter, fan blades, and a duct system. Each component requires specific cleaning methods to ensure optimal performance and longevity.

**Step-by-Step Cleaning Guide**

1. **Safety First**: Always start by turning off the power to your exhaust fan at the circuit breaker. This step is crucial for your safety.

2. **Dismantling the Fan**: Carefully remove the filter and any detachable parts. If you’re unsure how to dismantle your fan, consult the manufacturer’s manual.

3. **Soaking the Filter**: Submerge the filter in a mixture of warm water and a degreasing dish soap. Let it soak for at least an hour to loosen the grease and grime.

4. **Cleaning the Hood and Fan Blades**: Wipe the hood and fan blades with a degreaser or a mixture of baking soda and water. Use a soft-bristle brush or a non-abrasive sponge to avoid scratching the surface.

5. **Tackling the Ductwork**: For the ductwork, use a long-handled brush to gently scrub inside the duct. This step might require professional assistance if the ductwork is extensive or hard to reach.

6. **Rinsing and Drying**: After soaking, scrub the filter with a soft brush, rinse thoroughly, and let it air dry. Ensure all parts are completely dry before reassembling.

7. **Reassembling the Fan**: Once everything is dry, carefully reassemble the fan. Ensure all parts are securely fitted.

8. **Testing the Fan**: Turn the power back on and test the fan to ensure it’s working correctly.

**Maintenance Tips**

– Regular Cleaning: Clean your exhaust fan every few months to prevent heavy build-up.
