6 Kitchen Chimney Cleaning Hacks to Remove Stubborn Grease Easily

Newspoint
Keeping your kitchen chimney spotless does not always require expensive cleaners or harsh chemicals. In fact, a few simple household ingredients can make kitchen chimney cleaning much easier while effectively removing stubborn grease, oil stains, and sticky residue. Over time, chimney filters collect layers of smoke particles, cooking oil, and spice residue that can lead to unpleasant odours and reduced performance.

The good news is that regular maintenance with easy home remedies can help restore your chimney filters and outer surface without damaging the metal mesh or steel finish. Here are six simple kitchen chimney cleaning hacks that work surprisingly well for tackling oily buildup naturally.

1. Soak Filters in Hot Water and Baking Soda


One of the easiest ways to loosen thick grease is by soaking chimney filters in hot water mixed with baking soda. The heat softens hardened oil deposits, while baking soda helps break down sticky residue trapped inside the mesh.


How to use it:

  • Fill a bucket or sink with very hot water
  • Add 2–3 tablespoons of baking soda
  • Mix in a little dishwashing liquid
  • Soak the filters for 20–30 minutes

After soaking, gently scrub the filters using a soft brush or an old toothbrush. Avoid aggressive scrubbing, as it may damage delicate mesh layers.


2. Use Vinegar and Lemon to Cut Through Oil


Vinegar and lemon are commonly used in natural cleaning routines because their acidic properties help dissolve greasy buildup. This method is especially useful for removing oily stains and lingering cooking smells from chimney filters.

Steps to follow:

  • Mix warm water with vinegar and lemon juice
  • Spray or apply the solution on greasy areas
  • Leave it for a few minutes before wiping

This solution also works well on the chimney’s outer body, especially around buttons and steel panels where fingerprints and oil marks accumulate over time.

3. Clean with Dishwashing Liquid and Boiling Water


If you want a quick and simple method, dishwashing liquid combined with boiling water can work wonders. The hot water melts stubborn grease, while the soap separates oil from the metal surface.


Easy cleaning process:

  • Place filters in a deep tray or sink
  • Pour freshly boiled water carefully
  • Add a generous amount of dishwashing liquid
  • Let the filters soak for some time

Once soaked, rinse the filters under running water. Even if some dark stains remain, the sticky texture usually disappears significantly after one wash.

4. Try the Eno and Detergent Cleaning Trick


A surprisingly effective home hack involves using Eno fruit salt along with detergent. The fizzing reaction helps loosen greasy deposits stuck inside narrow filter holes.

How this method works:

  • Dissolve detergent in hot water
  • Add one packet of Eno
  • Place the filters into the bubbling mixture
  • Let them soak briefly before scrubbing lightly

This trick is particularly useful for filters with months of accumulated oil and grime. Since the mixture can produce a strong smell, keeping the kitchen ventilated during cleaning is recommended.

5. Apply Flour Before Washing Greasy Filters


A lesser-known but handy trick involves sprinkling flour or dry absorbent powder over oily surfaces before washing. The powder absorbs fresh grease and makes cleanup less messy.

Why this helps:

  • Prevents grease from spreading during washing
  • Makes slippery residue easier to wipe away
  • Reduces oily water buildup in the sink

This technique works best on recently formed grease rather than hardened stains. After dusting off the flour, you can proceed with normal soaking and washing methods.

6. Clean the Chimney Exterior Gently


The outer surface of a kitchen chimney gathers a thin layer of sticky dust and oil over time. Using harsh cleaners on steel finishes may leave streaks or dull patches, so mild cleaning solutions are often safer.

  • Best way to clean the outer body:
  • Use a soft cloth with mild soap water
  • Wipe gently around control buttons and corners
  • Use diluted vinegar water for stubborn spots
  • Avoid excess moisture near electrical panels

Regular gentle cleaning helps maintain the shine of the chimney while preventing greasy buildup from becoming difficult to remove later.


Kitchen chimney cleaning becomes much easier when done regularly with simple household ingredients. From baking soda soaks to vinegar solutions and the popular Eno trick, these easy hacks can help remove stubborn grease naturally without relying on strong chemical cleaners. With consistent maintenance, your chimney filters can stay cleaner, fresher, and more efficient for longer.
