How to Clean the Oven Hood Filter? Complete Guide

The oven hood filter plays a big role in keeping your kitchen clean and fresh. Over time, it collects grease, smoke, and dirt from cooking. If it is not cleaned, the filter can get clogged and stop working well. 

The good news is that cleaning it is easy and does not take much time. In this guide, you will learn simple steps to clean it properly and keep your kitchen smelling fresh.

Why Regular Cleaning Matters?

When you cook, steam and oil rise into the air. The hood fan pulls in this air, trapping grease inside the filter. Over time, these layers block airflow and create unpleasant smells. If left too long, the buildup can become a fire risk.

Regular oven cleaning keeps the fan working smoothly, prevents odors, and improves air quality in your kitchen. A clean filter also makes the motor last longer because it does not have to work as hard.

How Often Should You Clean the Filter?

The cleaning schedule depends on your cooking habits:

• Daily cooking → Clean every 2–3 weeks

• A few times a week → Clean monthly

• Occasional cooking → Every 2–3 months is fine

Sticking to a schedule makes cleaning the range hood filter easier, as grease does not have time to harden.

What You Will Need

Before starting, gather a few basic items you already have at home:

• Hot water

• Dish soap (a degreasing type works best)

• Baking soda

• A soft brush or toothbrush

• A clean towel or drying rack

• Rubber gloves (optional)

These simple supplies are enough to handle most grease buildup without using harsh chemicals.

Step-by-Step Guide to Clean the Oven Hood Filter

Step 1: Switch Off and Remove the Filter

Turn off the oven hood and let it cool. Locate the filter under the hood. Most filters slide or pop out easily. Check the manual if you are unsure.

Step 2: Prepare Hot Soapy Water

Fill the sink or a large basin with hot water. Add dish soap and stir until it becomes bubbly. Hot water helps soften grease quickly.

Step 3: Add Baking Soda

Sprinkle a few tablespoons of baking soda into the water and mix well. Baking soda is a natural cleaner that breaks down stubborn dirt without damaging the metal.

Step 4: Soak the Filter

Place the filter fully in the sink. Let it soak for 15–20 minutes. This loosens sticky grease so it can be scrubbed off easily.

Step 5: Scrub Gently

Use a soft brush or toothbrush to scrub the filter. Pay extra attention to corners and mesh areas where grime builds up. Avoid using steel wool, as it can damage the surface.

Step 6: Rinse Thoroughly

Rinse the filter under warm running water to remove soap and baking soda. Make sure no residue is left behind.

Step 7: Dry Completely

Place the filter on a clean towel or rack to dry fully. Moisture inside the hood can damage the fan, so make sure it is completely dry before reinstalling.

Step 8: Reinstall the Filter

Once dry, slide or snap the filter back into place. Turn the fan on to check that it runs smoothly again.

Deep Cleaning for Stubborn Grease

This technique works well during restaurant cleaning when you need to clean the oven hood filter surfaces covered with thick grease. Always be careful when using hot water.

1. Boil a large pot of water.

2. Slowly add baking soda to the boiling water.

3. Submerge the filter carefully for a few minutes.

4. Remove it with tongs and scrub gently.

This technique works well when you need to clean oven hood filter surfaces with thick grease layers. Be cautious when handling hot water.

Natural Cleaning Alternatives

Some people prefer natural cleaning methods. These are safe and effective when done regularly:

• Vinegar Spray: Mix equal parts vinegar and warm water. Spray on the filter, wait 10 minutes, then scrub and rinse.

• Salt and Baking Soda Paste: Mix salt, baking soda, and water to create a thick paste. Apply it to greasy spots before soaking.

• Lemon Water: Boiling lemon slices in water and soaking the filter helps remove both grease and odours.

These gentle methods are great for maintenance between deep cleans.

Tips to Keep the Filter Clean Longer

• Wipe the Hood Surface Regularly: A quick wipe after cooking keeps grease from building up.

• Use Lids While Cooking: This reduces splatter and steam, which means less grease reaches the filter.

• Turn on the Fan Early: Start the hood fan before cooking so it can catch steam right away.

• Replace Old Filters: If the filter is damaged or worn, replacing it is better than endless scrubbing.

Taking these small steps makes each cleaning session faster and easier.
