Does Merino Wool Smell? Natural Smell of Merino

Merino wool is known for its exceptional quality and performance in outdoor and activewear. Its natural properties make it breathable, moisture-wicking, and temperature-regulating, making it a popular choice for outdoor lovers and athletes.

However, one common concern that arises with merino wool garments is the potential for odor.

While merino wool is naturally odor-resistant, it is essential to understand how to care for merino wool and maintain this unique fabric to prevent any unpleasant odors.

To ensure that your merino wool clothing stays fresh and odor-free, we will examine the reasons behind the merino wool smell and provide practical tips on how to prevent and reduce it.

Let’s take a closer look at the reasons Merino Wool Smell.

What Causes Merino Wool to Smell?

Merino wool has many advantages and it is a popular choice for outdoor enthusiasts, athletes, and fashion lovers alike. It is known for its incredible softness, warmth, and moisture-wicking properties. However, one common issue that many people face with their Merino wool garments is an unpleasant odor that seems to linger even after washing.

Firstly, it’s important to understand Merino wool. It does not naturally smell. It has natural antibacterial properties that help to prevent odors from developing. However, there are a few factors that can contribute to that less-than-fresh scent. Merino Protect provides the best Merino wool t-shirts and our products do not smell.


One of the main culprits is bacteria. When we wear our Merino wool garments, our bodies naturally produce sweat. This sweat contains bacteria, and when it comes into contact with the fibers of the wool, it can create an environment where bacteria can thrive. These bacteria break down sweat, leading to the production of unpleasant odors.

When bacteria come into contact with sweat on wool clothing, they start breaking down the urea in sweat, resulting in the production of foul-smelling chemicals like ammonia and fatty acids. The presence of ammonia is what gives off that pee-like or urine smell that some people associate with wet wool.

Lanolin, a natural oil found in sheep’s wool, is the main culprit behind the distinct odor that emanates from wool garments. This oil serves a valuable purpose, as it helps to protect the sheep’s skin and keep the wool fibers soft and pliable, reducing any potential discomfort.

However, when combined with other substances, lanolin can contribute to an unpleasant scent in your Merino wool sweater. This is an important factor to consider when you wash your Merino wool sweater. The distinct smell of lanolin is often described as slightly sweet, earthy, grassy, metallic, or musky.

While not necessarily offensive, it can become overpowering in large quantities. Interestingly, some individuals find the scent of lanolin quite pleasant, while others may find it unpleasant, especially if the wool has been exposed to elements such as water.

When you wash your wool clothing, for instance, the lanolin can mix with sweat, bacteria, and dirt, resulting in a potent and undesirable odor. So, how can we prevent or eliminate the smell from our Merino wool garments? It’s good news that you can take several simple steps to improve your situation.

In the first place, proper care and maintenance are essential. It’s important to follow the manufacturer’s instructions for washing and drying your Merino wool garments. Most often, this involves a gentle machine or hand washing in cool water with a mild detergent designed for wool. Please don’t use harsh chemicals or bleach; they can damage the fibers.

Why Wool Smells After Washing

Have you ever noticed that your wool clothing or blankets smell after washing? It’s not uncommon, and there are several reasons why this may happen. One of the main culprits is lanolin, a natural oil found in wool. When wool gets wet, the lanolin can give off a distinct odor.

This odor can be intensified if the wool has been washed with harsh detergents or treated with chemicals like fabric softeners. These substances can react with the lanolin and create an unpleasant smell.

Another reason why wool smells after washing is improper rinsing or inadequate washing. If your wool item is not washed thoroughly or rinsed properly, the fibers can hold on to bacteria or sweat residue, leading to lingering odors.

It’s important to ensure that your wool items are washed properly to eliminate any potential odor-causing substances. Moisture can also play a role in the smell of washed wool. If wool clothing is stored before it is completely dry, it can develop a musty or damp smell.

This can happen if the wool is not properly dried after washing or if it is stored in a humid environment. To prevent this, make sure to thoroughly dry your wool items before storing them.

How to Get Rid of Wet Wool Smell

We all love the cozy comfort of wool, whether it’s a warm wool sweater or a soft wool blanket. But one thing that can really put on that cozy feeling is the unpleasant wet wool smell.

Here, we will explore some tried and tested methods to help you get rid of that wet wool smell and restore your woolen items to their fresh and fragrant state. Here are some tips for keeping away the question: does merino wool smell when wet?    

Activated Charcoal

When it comes to eliminating smells from wool, activated charcoal proves to be particularly effective as it traps the odor-causing molecules from the wool fibers.

To make use of activated charcoal during washing, place a small amount in a mesh bag or sock and add it to the washing machine or soak water when hand washing your wool garments.

This will allow the activated charcoal to absorb and eliminate any unwanted odors. Furthermore, when storing wool garments, you can prevent odor buildup by placing a small pouch or bag of activated charcoal near the clothes.

This will ensure that any odors or moisture that may be present are absorbed, keeping your wool garments smelling fresh and clean.

It is important to note that activated charcoal is not the same as regular charcoal or charcoal briquettes. Regular charcoal is not activated and may not possess the same odor-absorbing properties as activated charcoal.

Furthermore, regular charcoal or charcoal briquettes can contain harmful chemicals that are not suitable for use with wool clothing. Therefore, it is recommended to specifically use activated charcoal for odor removal in wool garments to ensure safe and effective results.

Use Vinegar

To get rid of the unpleasant odor of wet wool, vinegar can be an effective solution. Vinegar absorbs into wool fibers, neutralizing odor-causing bacteria. Its acidic properties also help break down residue and buildup on the fibers that may contribute to the foul smell.

There are two options for using vinegar in this case. For machine washing, add a cup of white vinegar to the washing machine and set it to a gentle cycle with cold water. The vinegar will eliminate the odor and freshen up the wool garment.

Alternatively, for handwashing, fill a basin or sink with cool water and a cup of white vinegar. Soak the wool garment in the mixture for approximately 15 minutes, allowing the vinegar to penetrate the fibers and remove any unwanted smell.

Once you have washed your wool item with vinegar, it’s important to let it air dry. Lay the garment on a flat surface, making sure it is spread out evenly. This will help the item retain its shape while it dries and prevents it from shrinking. Avoid hanging the garment, as this can cause it to stretch or lose its form.

Baking Soda

Baking soda is a versatile household item that can work wonders when it comes to neutralizing and removing odors, including that unpleasant wet wool smell.

The secret behind its effectiveness lies in its alkaline properties, which enable it to counteract the acidic odors caused by sweat and bacteria. Furthermore, baking soda can lift dirt and other particles that can contribute to those unwanted smells.

What makes baking soda particularly useful for treating the smell of wool clothing is its ability to absorb moisture and eliminate bacteria, both of which are responsible for the bad odor. To use baking soda on your wool garments, you can follow these simple steps.

  • Dissolve 1-2 tablespoons of baking soda in a sink or basin filled with cool water.
  • Add your wool garment to the solution and let it soak for a minimum of 30 minutes.
  • Rinse the garment thoroughly with cool water to remove any remaining baking soda.

If you prefer using a washing machine, you can still harness the power of baking soda. Simply add 1-2 tablespoons of baking soda to the machine along with your regular wool detergent. Then, wash the garment on a gentle cycle using cold water.

It is important to note that using too much baking soda can potentially damage delicate wool fibers, as it can be abrasive. Therefore, it’s best to stick to the recommended amount mentioned earlier.

Moreover, always check the care label of your wool garment to ensure that using baking soda is safe and suitable for it. Remember, prevention is key when it comes to avoiding the wet wool smell. Always make sure to dry your woolen items thoroughly after they get wet and store them in a clean and dry place.

Final thoughts

Merino wool can become smelly after washing despite its natural antibacterial properties. Factors like inadequate cleaning, improper drying, or exposure to external odors can cause this odor to develop.

The structure of wool fibers allows bacteria and sweat to get trapped, leading to the smell. To prevent this issue, it is important to follow care instructions, use a gentle detergent, rinse thoroughly, and ensure the wool is completely dry before storing. These steps help minimize the problem of odor effectively.


How Do You Get the Smell Out of Merino Wool?

To get the smell out of merino wool, soak the cloth in a mixture of cool water and 1/4 cup of plain white vinegar for 30 minutes. Merino wool is typically odor-resistant, but if any odors arise, this method should help eliminate them.

Why Does My Merino Smell?

Merino wool has natural properties that make it resistant to odors, but it can still develop a smell due to sweat and bacteria build-up.

The fabric’s moisture-wicking ability can trap sweat and bacteria, leading to odor. To prevent this, it is important to properly care for your merino wool garments by washing them regularly with a gentle detergent and allowing them to air dry.

Does Merino Wool Smell of Sweat?

Yes, merino wool is known for its natural odor-resistant properties, which make it less likely to retain and develop sweat-related smells compared to synthetic materials.

Why Does Wool Smell So Bad When Wet?

Wool can smell bad when wet due to a combination of factors. Firstly, wool has a natural oil called lanolin, which can become more pungent when exposed to moisture.

This is because water can break down the chemical compounds in lanolin, intensifying its odor. Additionally, when the wool gets wet, it can provide a favorable environment for bacteria and fungi to grow, leading to unpleasant smells.
