How to Prevent Stored Clothes Smell with Sodium Bicarbonate Before Travelling

Before travelling, it is worth preparing your wardrobe so you do not come home to clothes with that stale stored-away smell. Even when everything is clean, a closed space left shut for several days can build up humidity, limited airflow and the stuffy odour that seems to cling to fabrics. A straightforward way to prevent this is to place an open container of sodium bicarbonate inside the wardrobe before closing the doors.

Why does sodium bicarbonate help with stored clothes smell?

Sodium bicarbonate is an uncomplicated, inexpensive ingredient widely used to neutralise odours in small spaces. In a wardrobe, it can lessen the enclosed smell that develops when clothes have been left without ventilation for a long period.

It does not add fragrance in the way an air freshener does, which is precisely why it is well suited to clothing. Rather than combining perfume with an unpleasant smell, sodium bicarbonate helps keep the space more neutral. If preferred, it can then be paired with dried lavender, a scented cotton sachet or a few drops of essential oil on a separate piece of fabric.

How should you place it in the wardrobe before travelling?

Use a low, sturdy, open container. Add between half a cup and one cup of sodium bicarbonate, according to the size of the wardrobe. For smaller wardrobes, half a cup will usually be enough. In a large wardrobe or one filled with clothing, two containers can be positioned in different areas.

Place the container on a lower shelf, in a corner of the wardrobe, away from the edge and without letting it touch the clothes directly. Where there is a chance of spilling, put the sodium bicarbonate in a breathable fabric sachet or cover the pot with a piece of tulle secured with an elastic band.

How long does the effect remain active?

For a short trip lasting a few days, sodium bicarbonate can already help prevent the wardrobe from becoming too stuffy. Over longer periods, it may continue working for several weeks, provided the container remains dry and is not exposed to direct moisture.

If the sodium bicarbonate starts to form lumps, darken or no longer looks loose, it has absorbed moisture and should be replaced. In wardrobes used every day, it can be changed every one or two months. Before a long journey, it is best to use fresh sodium bicarbonate.

How can you prevent a musty smell while you are away?

Sodium bicarbonate is helpful, but it cannot work miracles if the wardrobe is already damp or mouldy. Before leaving, open the doors for a few hours, allow air to circulate and store only clothes that are completely dry. Slightly damp items are among the most common causes of bad smells after days in a closed wardrobe.

Avoid packing the wardrobe too tightly as well. When it is overcrowded, there is less air circulation and the stored-away smell develops more quickly. Where possible, leave a small gap between hangers and avoid placing clothing directly against the back wall, especially in more humid bedrooms.

What other steps keep clothes fresh when you return?

As well as sodium bicarbonate, you can place dried lavender sachets, cedar pieces or activated charcoal at strategic points in the wardrobe. These items help make the space more pleasant while you are away, particularly in drawers, top storage compartments and rarely used shelves.

The secret to returning from a trip and finding clothes without a stored-away smell is to combine three simple measures: a clean wardrobe, thoroughly dry clothes and a well-positioned odour absorber. By putting a container of sodium bicarbonate inside before shutting the doors, the wardrobe will stay fresher, less stuffy and far more pleasant when you get home.
