02 Oct The Science Behind Odour: Why Clothes Smell and How to Remove Clothes Odour

Unpleasant odours in our clothes can be a common and frustrating issue. Whether it’s the lingering smell of sweat, musty odours from storage, or cooking aromas that have clung to our garments, these odours can be bothersome and embarrassing. But have you ever wondered why clothes develop odours in the first place? In this blog post, we will delve into the science behind why clothes can smell and explore effective methods for removing clothes odour and keeping your wardrobe fresh and pleasant.

The Science of Clothes Smell

1. Sweat and Bacteria

One of the primary reasons clothes develop odours is due to the interaction between sweat and bacteria. When we sweat, our body releases moisture that contains various compounds, including amino acids and fatty acids. These compounds provide an ideal environment for bacteria to thrive. Bacteria on our skin break down these compounds, leading to the production of foul-smelling substances, such as isovaleric acid and butyric acid.

As we wear clothes, sweat is absorbed into the fabric, and bacteria continue to break down these compounds, releasing odorous molecules. This is why workout clothes, in particular, tend to develop strong odours over time.

2. Trapped Odours

Trapped odours in clothes occur when molecules from the surrounding environment adhere to the fabric’s fibres and become embedded. These odours can originate from a variety of sources, including:

1. Cooking: The aromatic compounds from your cooking can permeate your clothing, especially if you’re preparing meals with strong spices or ingredients.
2. Tobacco Smoke: If you or someone in your household smokes indoors, clothes can easily absorb the scent of tobacco smoke, which is notoriously difficult to remove.
3. Storage: Clothes stored for an extended period in spaces with poor ventilation, like attics or basements, can develop musty odours due to mould and mildew growth.
4. Pets: If you have pets, their fur and dander can leave a lingering odour on your clothes, particularly if they frequently sit or sleep on your garments.
5. Outdoor Activities: Clothes worn during outdoor activities like camping or fishing may pick up odours from the natural environment, such as campfires or fishy scents.

3. Mildew and Mould

Clothes that are stored in damp or humid conditions are susceptible to developing odours caused by mildew and mould. These microorganisms thrive in moisture-rich environments and can produce a musty smell when they grow on fabrics.

1. Humidity and Moisture: Mildew and mould growth on clothes are primarily triggered by excess humidity and moisture. When clothes are stored in damp or humid environments, such as basements, garages, or closets with poor ventilation, the moisture provides an ideal breeding ground for these fungi.
2. Spore Activation: Mold and mildew spores are present in the air around us. When they come into contact with a damp fabric, they can germinate and begin to grow, leading to the development of colonies that emit that musty odour.
3. Stains and Fabric Damage: In addition to the unpleasant odour, mildew and mould can cause visible stains and fabric damage. Clothes with long-term mould growth may be permanently discoloured and weakened.

Removing Clothes Odour

Now that we understand why clothes can develop odours, let’s explore tips for removing clothes odour and keeping your wardrobe fresh effectively.

1. Proper Washing

The most fundamental step in removing clothes odour is proper washing. Here are some tips:

• Sort your laundry: Separate heavily soiled or odorous items from clean ones.
• Use the right detergent: Choose a detergent that is effective against odours and suitable for your fabric type.
• Pre-treat stains: Treat any visible stains before washing.
• Wash at the right temperature: Follow the care instructions on your clothing labels to ensure you wash them at the appropriate temperature.
• Use vinegar or baking soda: Adding a cup of white vinegar or baking soda to your laundry can help neutralize odours.
• Dry in the sun: Sunlight has natural deodorizing properties, so hang your clothes outside to dry if possible.

2. Odour-Neutralizing Products

Consider using commercial odour-neutralizing products like fabric sprays or scent-boosting beads. These products can help in removing clothes odour and leave your clothes smelling fresh.

3. Air Out Your Clothes

After wearing clothes, hang them up to air out before putting them back in your wardrobe. This allows moisture and odours to dissipate, preventing them from becoming trapped in the fabric.

4. Proper Storage

Store your clothes in a clean, dry, and well-ventilated environment. Avoid leaving clothes in damp or musty spaces, as this can lead to the growth of mildew and mould.

5. Freezing Method

For clothes unsuitable for washing, such as delicate fabrics, consider using the freezing method. Place the item in a plastic bag and put it in the freezer for a few hours. The cold temperature will kill bacteria and help eliminate odours.

6. Steam Cleaning

For fabrics that cannot be washed, such as curtains or upholstery, steam cleaning can be an effective way to remove odours. Steam penetrates the fabric and kills bacteria, leaving your items refreshed.

The Role of Fabric Softeners in Eliminating Odours

1. Odour Neutralization

Fabric softeners contain fragrances that are released during the drying cycle, infusing your clothes with pleasant scents. These fragrances can be effective for removing clothes odour, leaving your laundry smelling fresh and clean. The fragrances of fabric softeners can linger on fabrics. This provides a longer-lasting scent compared to detergents alone.

2. Softening and Fluffing

While not directly related to odour removal, fabric softeners play a crucial role in softening and fluffing your clothes. This can help improve airflow during the drying process, reducing the chances of moisture and odours becoming trapped in the fabric. Soft, fluffy fabrics are less likely to hold onto unpleasant smells, making it easier for your laundry to smell fresh.

3. Anti-Static Properties

Static electricity can contribute to the development of odours in clothes. Fabric softeners help eliminate static cling, preventing clothes from sticking together during the drying process. When you separate clothes, air circulates more freely, reducing the likelihood of odours forming.

How to Use Fabric Softeners Effectively

To make the most of fabric softeners in removing clothes odour, follow these tips:

1. Choose the Right Fabric Softener: Select a fabric softener with a fragrance that you find pleasant and that complements your laundry. There are various scents available, from floral to citrusy, so you can tailor your choice to your preferences.
2. Use the Recommended Amount: Be sure to follow the manufacturer’s instructions for the correct amount of fabric softener to use. Using too much can leave a residue on your clothes and potentially diminish their breathability.
3. Add it at the Right Time: You should add most fabric softeners during the rinse cycle of your washing machine. Consult your machine’s manual for specific instructions.
4. Keep Your Machine Clean: Periodically clean your washing machine and fabric softener dispenser to prevent any build-up that could affect the effectiveness of the softener.

The Last Word

Understanding the science behind clothes odour is the first step towards removing clothes odour. By following proper washing techniques, using odour-neutralizing products, maintaining good storage practices, and considering alternative methods like freezing and steam cleaning, you can keep your clothes smelling fresh and enjoy a pleasant wardrobe. Say goodbye to unwanted odours and embrace the science of freshness in your daily attire.
