How to Maintain Your Kitchen Chimney for Optimal Performance

The kitchen chimney is a modern kitchen’s unsung hero. Whether you're deep-frying, sautéing, or pressure-cooking, your chimney silently removes smoke, grease, and odors, keeping your cooking environment fresh. But just like any hardworking appliance, it needs regular care to keep functioning at its best.

Neglecting chimney maintenance can lead to reduced suction power, unpleasant smells, clogged filters, and even safety hazards over time. In this guide, we’ll explore everything you need to know to maintain your kitchen chimney and ensure it delivers optimal performance every day.

Why Is Chimney Maintenance Important?

Before we jump into how to clean it, let’s understand why chimney maintenance matters:

• Improves suction efficiency: Regular cleaning keeps airflow smooth, enabling maximum suction of smoke and grease.

• Enhances hygiene: A greasy, unclean chimney can attract pests and become a breeding ground for germs.

• Increases lifespan: Maintenance prevents wear and tear, helping your chimney last for years.

• Prevents odors and fire hazards: Built-up oil and carbon residue can ignite or cause unpleasant odors.

• Keeps your warranty valid: Many brands require periodic servicing to keep the warranty intact.

Understand Your Chimney Type Before Cleaning

There are different types of kitchen chimneys, and each requires a specific cleaning approach:

Knowing your chimney’s design helps you choose the right cleaning method and schedule.

Step-by-Step Chimney Maintenance Routine

1. Turn Off and Cool Down

Before beginning any cleaning process:

• Please switch off the chimney and unplug it from the power socket.

• Let it cool completely to avoid burns or electric shock.

2. Remove the Filters Carefully

Most chimneys come with detachable filters. Gently unlock and remove them. Be sure to read your user manual for exact instructions.

3. Soak the Filters in a Cleaning Solution

Use any of the following DIY mixtures:

• Hot water + baking soda + dishwashing liquid

• Hot water + vinegar + lemon juice

Soak the filters for 30–45 minutes to loosen the grease. Then scrub with a soft brush.

Avoid using steel wool or metal scrubbers that can damage the filter coating.

4. Wipe the Chimney Hood and Exterior

Use a soft microfiber cloth dipped in warm soapy water to clean:

• The outer body

• Control panel (gently wipe, avoid water inside)

• Glass surfaces (if applicable)

Dry it thoroughly with a cloth to avoid water stains.

5. Clean the Oil Collector (Filterless Chimneys)

If you have an auto-clean chimney:

• Remove the oil collector tray from beneath.

• Wash it with detergent and hot water.

• Let it dry completely before placing it back.

6. Run Auto-Clean Function (If Available)

Some filterless chimneys have a built-in auto-clean button. When pressed:

• The heating element melts grease into the oil collector tray.

• Just empty and clean the tray afterward.

Run the auto-clean function once every 15–20 days for best performance.

7. Check and Replace Charcoal Filters

Charcoal filters (found in ductless chimneys) cannot be washed. They should be:

• Replaced every 3 to 6 months, depending on cooking frequency.

• Checked if suction is weak or odors persist.

8. Inspect the Exhaust Pipe

The duct pipe carries smoke outside your home. Check for:

• Grease buildup

• Bird nests or obstructions

• Loose connections

Wipe the outer duct section every 3 months and schedule professional cleaning once a year.

9. Homemade Cleaning Hacks

If you don’t have chimney cleaning products, here are some DIY tricks:

• Vinegar + Warm Water: Great for cutting grease on glass tops and hoods.

• Baking Soda Paste: Acts as a natural degreaser when applied to tough spots.

• Lemon Wipe: Rubbing lemon halves on the surface helps break down grease & leaves a fresh scent.

These are safe, chemical-free, and budget-friendly cleaning options.
