Learn about the benefits of this trick and how to do it correctly. The cupboard is one of the most used spaces and, at the same time, one of the most prone to accumulating moisture, bad odours and a certain ‘heaviness’ in the environment, especially in cold seasons or in homes with poor ventilation. According to experts in home organisation and natural cleaning, this enclosed environment can retain odours from stored clothing, footwear and textiles, affecting both the freshness and overall energy of the room. In this context, experts in household tricks have revealed a simple, economical and very effective practice for improving the indoor environment: placing half an onion inside the wardrobe.
Why onions are the secret to a fresher and more balanced wardrobe
Onions have absorbent and deodorising properties that help neutralise strong odours, retain moisture and limit the proliferation of fungi in enclosed spaces. When placed inside the wardrobe, they act as a natural purifier that improves air quality and prevents clothes from smelling musty.
In addition, their ability to capture environmental moisture makes them ideal for cupboards where odours from stored clothing, perspiration or moisture from cold or poorly ventilated walls tend to accumulate.
In Feng Shui, onions are also considered an element capable of capturing the ‘dense energy’ associated with stagnation and lack of circulation. Many experts recommend their use in areas where clothes are stored for long periods of time, as these areas tend to absorb emotions and charges that remain trapped in textiles and personal items.
Thus, onions become an economical, natural and effective alternative for those looking to keep their clothes fresh without using artificial fragrances, electric dehumidifiers or chemicals.
The benefits of placing onions in the wardrobe

- Absorbs moisture: reduces the smell of confinement and prevents the feeling of a stuffy environment.
- Neutralises bad odours: especially those coming from stored clothes, shoes or fabrics.
- Acts as an energy barrier: according to energy disciplines, it helps to clear dense vibrations associated with stagnation.
- Limits fungi and bacteria: onions inhibit proliferation in damp or poorly ventilated places.
- Improves the freshness of the space: makes the wardrobe lighter and more pleasant for everyday use.
Step by step: how to use onions in the wardrobe
- Choose white or yellow onions, as they are more effective at absorbing moisture and odours.
- Cut them in half to activate their absorbent effect.
- Place the halves on a small plate or bowl.
- Place it inside the cupboard, preferably on a shelf where it will not touch the clothes.
- Leave it to work for 24 to 48 hours, depending on the level of humidity or odour.
- If it becomes too damp or changes colour, discard it and replace it.
- To enhance the effect, you can place two halves in different areas of the cupboard.
How often should the onion be replaced to keep the wardrobe fresh?
The frequency depends on the climate and the level of humidity in the environment. In humid homes or very closed wardrobes, experts advise replacing the onion every two or three days, or even daily if it is very saturated. In drier homes, it can be replaced every five or seven days without any problems.
This simple routine not only helps to prevent bad odours, but also improves the energy circulation in the room and creates a feeling of freshness in clothes and textiles.
