Eliminating unpleasant odours in the kitchen: signs, causes and solutions

Unpleasant odors in the kitchen can quickly become persistent and overwhelming. Food residues, dirty appliances, humidity, or insufficient ventilation: several factors may be involved.

But one element is often underestimated: indoor air quality.

Indeed, even after thorough cleaning, invisible particles can remain suspended in the air and continue to spread unpleasant smells.

This article aims to help you identify the causes of kitchen odors, adopt effective natural solutions, and understand why improving air quality is sometimes essential to permanently eliminate these odors.

Natural Products to Eliminate Kitchen Odors

To eliminate kitchen odors, you need to act in three steps:

1. Remove the visible source
2. Clean the surfaces
3. Treat the air if necessary

1. Remove the Source of Odors

Baking Soda

Baking soda is a highly effective natural neutralizer. You can apply it directly to odor-prone surfaces, such as the bottom of a trash bin or a sink, and let it sit for a few minutes to several hours depending on the strength of the odor.

For example, you can place some in a small bowl in your refrigerator overnight to act on the trapped air inside. This natural neutralizer has the advantage of absorbing odor-causing molecules without adding artificial fragrance.

However, if you need to treat hard-to-reach areas, such as pipes, you may need to combine it with white vinegar, which has a slight smell but ensures effective cleaning.

White Vinegar

White vinegar eliminates bacteria and residues thanks to its acidity. You can use it as a cleaning product, for example on surfaces (sink, countertops) or inside your appliances (microwave, dishwasher). It helps treat bacterial sources responsible for unpleasant odors.

Its advantage is also that it is liquid: you can dilute it with hot water and pour it into your pipes, such as in your sink, to reach hard-to-access areas.

Citrus Fruits and Essential Oils

Citrus fruits provide a natural freshness and help dissolve grease. Placing a lemon in the sink is an old-fashioned trick that can be effective for mild odors, limescale, and more.

Essential oils (lemon, eucalyptus, lavender) mainly serve to scent the air. They mask odors but do not eliminate the root cause.

2. Clean the Kitchen Effectively

Surface Cleaning

A good habit to prevent odors: regularly clean “high-risk” areas, such as countertops, stovetops, sinks… as well as spots prone to bacteria, like door handles and appliance handles.

Standard cleaning products, like disinfecting wipes and sprays, work very well. Otherwise, a paste of baking soda + water effectively degreases stubborn surfaces.

Appliances

Some enclosed appliances trap air and odor particles, which accumulate over time. For example, it is recommended to:

• Clean the refrigerator every month
• Degrease the oven regularly
• Run an empty vinegar cycle in the dishwasher
• Clean the range hood filters

These are habits we know but often forget. Add them to your routine, especially if odors become a concern!

Pipe Maintenance

As explained earlier, the most effective method is to regularly pour baking soda, followed by vinegar diluted with hot water, into the sink. This maintains your pipes efficiently without using harmful chemicals. In case of persistent odors, check the trap or use a plumbing snake to remove anything potentially stuck, like food debris.

3. Improve Your Kitchen’s Air Quality

Even after a complete cleaning, invisible particles responsible for odors may remain. This is when you need to treat the source: your kitchen’s air.

The Importance of Ventilation

Odors are caused by an accumulation of particles. By renewing the air, you reduce this risk and may even solve existing odor problems.

Adopt habits to improve ventilation, such as always using the range hood while cooking, cleaning the filters regularly, and airing the room whenever possible. However, ventilation alone can sometimes be insufficient, especially in closed or poorly exposed kitchens.

Purify the Air to Eliminate Odor-Causing Particles

Unpleasant odors are not just “bad smells”: they are suspended particles. To treat them directly, an air purifier is the most effective:

• An air ionizer is a purifier that works by releasing negative ions into the air, which attach to harmful particles (including pollutant and odor-causing ones). This makes them attracted to surfaces, like the floor, removing them from the air you breathe.
• A purifiable filter air purifier draws in ambient air and captures particles responsible for odors through a filtration system. It is slightly noisy compared to an ionizer, but still quieter than a refrigerator, making this solution popular for kitchens.

These air purification solutions have the advantage of eliminating odors at their source: at the particle level. This is ideal for getting rid of persistent odors (while also improving indoor air quality, which is already beneficial for health). Consider trying this type of solution especially when:

• Cooking odors persist despite cleaning
• Ventilation is limited or insufficient
• Odors settle into textiles

Conclusion

Eliminating kitchen odors is not just about cleaning surfaces. It involves addressing the root causes: food residues, bacteria, humidity… and especially, particles suspended in the air. It is therefore an issue of not only hygiene but also health.
