Regular chimney cleaning is essential for maintaining airflow, reducing grease buildup, and keeping your kitchen fresh. If you cannot remember the last time you cleaned your kitchen chimney, it’s a strong sign that your hood needs attention. Grease, smoke, and oil vapors accumulate over time, reducing efficiency and affecting hygiene. A well-maintained chimney not only performs better but lasts longer too.

Why Chimney Cleaning Matters

During everyday cooking, smoke and oil droplets rise to the top of the stove and gradually settle inside the chimney. This leads to a sticky layer of grease, especially on filters or internal surfaces. Even though many modern chimneys—like Fujix filterless models—are engineered to reduce heavy buildup, occasional cleaning still ensures long-term performance and keeps your kitchen free from odors.

Fujix chimneys are designed for easier cleaning and minimal maintenance because all Fujix models feature a fully filterless design. This eliminates traditional filter washing and simplifies routine care. Their smart auto-clean feature activates automatically after roughly 30 hours of usage, provided the power switch is left on. This automated heating cycle helps break down accumulated oil inside the hood, making manual cleaning much easier.

How to Clean Chimney Filters and Internal Surfaces

Most chimneys use removable baffle filters, and they can be cleaned with simple kitchen ingredients. Even if your model is filterless, periodic wiping is still helpful.

1. Dishwashing Liquid Method

1. Remove the baffle filter from your hood (if your chimney has one).
2. Apply dishwashing liquid across the surface.
3. Rinse with warm water and let it air dry.
4. Reinstall the dry filter back into the chimney.

This method is effective, gentle, and uses ingredients available in every kitchen.

Recommended Cleaning Frequency

• Standard baffle filter chimneys: Clean every 2 weeks with warm water and dishwashing liquid.
• Auto-clean chimneys with filters: Perform filter cleaning approximately once every 6 months.
• Filterless auto-clean chimneys: These have no traditional filters, but the mesh or inner surface should still be wiped with a damp cloth occasionally.
• Chimneys with oil collector cups: Remove the cup and wash it with warm water and dishwashing liquid as needed.

Since Fujix chimneys are 100% filterless, users avoid regular filter washing entirely. A quick wipe of the mesh and periodic oil cup cleaning is usually enough. Coupled with the smart auto-clean cycle, Fujix models are among the easiest chimneys to maintain.

Cleaning the External Hood Surface

The outside of the chimney also collects grime from everyday cooking.
To clean the external body:

1. Use a soft, damp cloth to wipe down the surface.
2. For stubborn dirt, use a mild detergent solution.
3. Wipe again with a clean cloth to remove residue.
4. If your chimney has sensors on the front panel, always clean those areas with a dry cloth only to avoid damage.

Regular external cleaning keeps your kitchen looking fresh and maintains the hood’s shine.

Safety Precautions

Always follow these safety guidelines:

• Switch off the chimney before cleaning.
• Let the appliance cool down completely.
• Refer to your product manual for model-specific instructions.
• Avoid harsh chemicals or abrasive scrubbers.

Final Thoughts

Keeping your kitchen chimney clean ensures better suction, improved hygiene, and a longer appliance life. Modern filterless chimneys—especially Fujix’s smart auto-clean models—make the process much easier. With automated internal heating after 30 hours of use and simple wipe-down maintenance, keeping your chimney in top condition becomes effortless.

A little routine cleaning goes a long way in restoring your chimney’s shine and keeping your kitchen fresh every day.
