Rangehood filters collect grease, smoke and cooking residue much faster than most people realise, and when they become clogged, your kitchen starts to smell, airflow weakens and the hood becomes noisy or less effective. The good news is that cleaning them doesn’t have to be difficult or time consuming. Whether your filters are lightly dusty or completely covered in stubborn grease, this guide will show you exactly how to clean them quickly, safely and like a professional using simple household items you already have.
What You Need Before You Start Cleaning Rangehood?
You don’t need any specialised equipment to clean rangehood filters properly. Most of the items required are already in your kitchen. Gather these before you begin to make the process faster and easier:
- A large pot or deep sink for soaking
- Boiling water
- Baking soda
- Dishwashing liquid
- A soft brush or old toothbrush
- Microfibre cloths for drying
- White vinegar (optional for heavy grease)
Having everything ready ensures a smooth cleaning process and helps the grease break down more effectively.
How to Clean Rangehood Filters Step-by-Step Like a Professional
Cleaning rangehood filters properly requires only a few simple steps. Follow this professional method for the best results:
1. Remove the Filters Safely
Turn off the rangehood, allow it to cool and gently slide or unclip the filters. Most filters lift out easily, but avoid forcing them to prevent bending the frame.
2. Shake Off Loose Dust and Debris
Give the filters a light shake or tap over the sink or bin to remove loose particles. This helps the cleaning solution work more effectively.
3. Prepare a Hot Cleaning Solution
Fill a large pot or sink with boiling water. Add a generous amount of baking soda (2–3 tablespoons) and a squeeze of dishwashing liquid. Stir to dissolve.
4. Submerge the Filters Completely
Place the filters into the hot solution. The water should immediately start cutting through grease. Leave them to soak for 10–20 minutes depending on how dirty they are.
5. Scrub Gently to Remove Remaining Grease
Use a soft brush or old toothbrush to clean the mesh. Avoid using abrasive brushes they can damage aluminium filters.
6. Rinse Thoroughly with Hot Water
Rinse away all the loosened grease and cleaning residue. Hot water helps dissolve any remaining oils.
7. Let the Filters Air Dry Completely
Place the filters upright or on a clean towel and allow them to dry fully. Installing them while damp can lead to mould or poor airflow.
8. Reinstall the Filters
Once dry, slot the filters back into the rangehood securely. You should notice improved airflow and reduced kitchen odours immediately.
How to Deep Clean Extremely Greasy Rangehood Filters?
If your rangehood filters haven’t been cleaned for months or are coated in thick, sticky grease, a standard soak may not be enough. This deep-cleaning method helps break down heavy build-up and restore the filters to near new condition.
1. Create a Stronger Degreasing Solution
Fill your sink with boiling water and add:
- ½ cup baking soda
- ½ cup white vinegar
- A generous squeeze of dishwashing liquid
The combination of baking soda and vinegar creates a natural chemical reaction that helps dissolve stubborn grease.
2. Soak the Filters for 20–30 Minutes
Fully submerge the filters. You’ll notice the water turning cloudy as grease lifts from the mesh.
3. Scrub Using a Soft Brush
After soaking, gently scrub the mesh in circular motions. Focus on areas where grease is visibly trapped. Avoid using steel wool, as it can scratch and damage the metal.
4. Repeat the Soak if Necessary
For extremely oily filters, you may need to repeat the soak with fresh hot water and more baking soda. This step ensures deep penetration through thick layers of grease.
5. Rinse with Very Hot Water
Rinsing with hot water helps melt and remove the loosened grease, revealing a cleaner and clearer mesh pattern.
6. Dry Thoroughly Before Reinstalling
Allow the filters to air dry completely. Any trapped moisture can lead to mould or reduced extraction performance.
This deep-cleaning method is ideal for households that cook frequently, use oily ingredients or haven’t cleaned their rangehood for an extended period.
How to Clean Filters Using Vinegar, Baking Soda & Other Natural Methods?
If you prefer eco-friendly cleaning methods or want to avoid harsh chemicals, several natural ingredients can effectively break down grease and lift dirt from rangehood filters. These solutions are safe, affordable and easy to use.
1. White Vinegar
A powerful natural degreaser.
Mix equal parts vinegar and hot water, then soak the filters for 10–15 minutes. Vinegar helps dissolve oils and neutralise lingering kitchen odours.
2. Baking Soda
One of the most effective grease-cutting ingredients.
Add 2–4 tablespoons of baking soda to boiling water and stir. It binds with oils, lifts grease and softens tough build-up without damaging the metal.
3. Vinegar + Baking Soda Combo
For maximum cleaning power.
When combined, the fizzing reaction helps break down heavy grease lodged deep in the mesh. Ideal for filters that haven’t been cleaned in a long time.
4. Lemon Juice
A natural antibacterial and deodoriser.
Add a few tablespoons to hot water for a fresh scent. Works well for light-to-moderate grease.
5. Dishwashing Liquid
Gentle but extremely effective.
Choose a high-quality degreasing formula. Works best when combined with baking soda in hot water.
These natural solutions not only clean effectively but also help maintain the longevity of your filters by avoiding abrasive chemicals.
Common Mistakes Cleaning That Make Filter Grease Worse:
Cleaning rangehood filters is simple when you are doing house cleaning, but a few common mistakes can cause damage or make the cleaning process far less effective. Avoid these pitfalls to ensure the best results every time:
1. Using Abrasive Brushes or Steel Wool
These can scratch aluminium filters and damage the mesh. Once scratched, grease begins building up much faster.
2. Not Using Hot Enough Water
Warm water won’t break down grease properly. The hotter the water (ideally boiling), the more effective your cleaning results will be.
3. Using Bleach or Harsh Chemicals
Strong chemicals can corrode metal filters and produce strong fumes when the rangehood heats up. Natural solutions are safer and just as effective.
4. Reinstalling Filters Before They’re Fully Dry
Trapped moisture can lead to mould, unpleasant smells and reduced airflow. Always let filters air dry completely.
5. Cleaning the Filters Too Infrequently
Waiting too long allows grease to harden and clog the mesh, reducing extraction power and putting strain on the motor. Regular house cleaning prevents damage and keeps your kitchen fresher.
Avoiding these common mistakes will help your rangehood perform better, last longer and stay cleaner between maintenance sessions.
How Often Should You Clean Your Rangehood Filters?
How frequently you should clean your rangehood filters depends on how often and what type of food you cook. Grease, steam and smoke accumulate faster in some households than others, but as a general rule:
Light Cooking (1–2 times per week)
Clean every 2–3 months.
Soups, boiling and simple meals produce minimal grease.
Moderate Cooking (3–5 times per week)
Clean every 4–6 weeks.
Frying occasionally, sautéing and oven use create steady grease build-up.
Heavy or Daily Cooking
Clean every 2–3 weeks.
Regular frying, grilling, or cooking oily foods will clog filters quickly.
Commercial or Large Family Kitchens
Clean every 1–2 weeks for optimal performance and hygiene.
Regular house cleaning helps maintain strong airflow, reduces odours and prevents grease fires. A clean filter also improves the efficiency and lifespan of your rangehood motor.

Frequently Asked Questions (FAQ)
1. What is the quickest way to clean rangehood filters?
The fastest method is soaking the filters in boiling water, baking soda and a small amount of dishwashing liquid. This breaks down grease within minutes and requires minimal scrubbing.
2. Can I put my rangehood filters in the dishwasher?
Yes, most metal mesh filters are dishwasher safe. However, extremely greasy filters may not come out fully clean, and dishwasher detergent can sometimes dull the metal. Always check your manufacturer’s instructions first.
3. Why do my rangehood filters still smell after cleaning?
Lingering odours usually mean grease remains deep inside the mesh. Try a second soak with baking soda and white vinegar, or consider professional kitchen cleaning if the smell persists.
4. How do I know if my filters need replacing instead of cleaning?
If the mesh is damaged, bent, rusted or permanently discoloured, cleaning will no longer restore proper airflow. In these cases, replacing the filter is the safest and most effective solution.
5. Do professionals clean rangehood filters during a kitchen deep clean?
Yes. Professional cleaners such as A Max Clean Group in Adelaide, Melbourne, Darwin and Perth include rangehood filter cleaning, degreasing and full kitchen sanitation as part of their deep cleaning services.
