Your towels come out of the tumble dryer soft, and two days later they smell like the dampness of the closet. Many families know this nuisance, especially in windowless bathrooms where humidity gets trapped. Among the remedies passed down through generations, one gesture intrigues: slipping a bay leaf into the storage.
A musty odor isn’t just about an unpleasant scent; it signals the presence of microorganisms that thrive on textiles that are still slightly damp. In a bathroom closet, the air circulates poorly, humidity is trapped between stacks of sponges and the cold walls. Bay laurel, used since antiquity to preserve foods, can limit this phenomenon. Provided you know which leaf to use, and especially how to place it.
In the bathroom, your towels smell musty in the closet for this precise reason
According to the Centre Scientifique et Technique du Bâtiment and ADEME, the ideal humidity for a bathroom lies between 50% and 70%. In a closed cabinet, this hygrometry can rise to 85%, especially after a hot shower or if the door remains closed all the time. Towels then absorb the steam, maintain a slight dampness, and offer a fertile ground for invisible mold growth.
Microscopic fungi like Aspergillus develop on the surface of fibers when the air is humid and stagnant. They are the ones that produce that characteristic smell of laundry left too long in a bag or basket. Air the closet, let the bath linens dry completely, and reduce clutter—that remains the foundation. A vegetal scent with antifungal properties, such as that of the bay leaf, comes in as a supplementary aid.
Bay laurel leaf: essential oils and antifungal effect on laundry
The bay laurel, Laurus nobilis, is a Mediterranean shrub in the family Lauraceae, not to be confused with the laurel rose, ornamental and highly toxic. Its leaves contain between 0.8 and 3% essential oils. Elements such as 1,8-cineole and eugenol are found, along with other aromatic compounds. Texts in phytotherapy describe for these leaves antibacterial and antifungal properties.
These aromatic molecules diffuse slowly into the air of a small closed space like a closet. They disrupt the membranes of certain bacteria and fungal spores, thereby limiting their settlement on dry textiles. The effect is modest but real as a preventive measure: the bathroom closet smells fresher, musty odors reappear less quickly. The bay leaf does not address a structural humidity problem; it complements ventilation and proper drying.
How to use bay laurel in the closet without damaging your towels
For this trick, only the well-dried bay leaf works. It is simply dried flat on a clean cloth or in a bouquet, head downward, in a well-ventilated place for at least fourteen days. A fresh leaf contains about 80% water; sealed in a dark closet, it releases this water, increases humidity further, and can stain cotton towels. Once your leaves are perfectly dry and your towels are fully wrung out or air-dried, you can adopt a small, simple routine.
- Slip 3 to 5 dry leaves into a small breathable cotton pouch.
- Place a sachet near each stack of towels, without burying it entirely.
- Replace the sachets about every 3 months or as soon as the scent becomes very faint.
This system lightly perfumes the laundry and helps slow the appearance of the musty odor on clean towels. If there are mold spots or a very strong odor already present, you must rewash the laundry, check the bathroom ventilation, and address the humidity cause before using bay laurel. The bay leaf provides a natural boost, as long as it remains dry, discreet, and clearly identified as bay laurel.
