What Homemade Solutions Can Deodorize Musty Crib Mattresses?

Why do crib mattresses become musty?

Musty odors in crib mattresses can be a cause for concern. It is important to understand why these odors occur in order to address the issue effectively.

Moisture buildup

One common reason for musty odors in crib mattresses is moisture buildup. When a mattress is exposed to moisture, such as from spills, leaks, or excessive sweating, it creates an environment for mold and mildew to thrive. If these spores are not addressed promptly, they can lead to unpleasant smells and potentially even health issues.

Lack of air circulation

Another factor that contributes to musty crib mattresses is the lack of proper air circulation. When a mattress is not given the opportunity to breathe, moisture becomes trapped, leading to the growth of mold and mildew. This can happen when mattresses are placed directly on the floor or covered with impermeable materials.

Presence of mold or mildew

Lastly, the presence of mold or mildew itself can cause musty odors. Mold and mildew are fungi that thrive in damp environments and can release volatile organic compounds (VOCs) that produce unpleasant smells. If mold or mildew growth is not addressed promptly, it can spread and cause further damage to the mattress.

Natural deodorizers for musty crib mattresses

Thankfully, there are natural deodorizers that can help eliminate musty odors from crib mattresses. These alternatives to harsh chemicals are safe for babies and allergy-prone individuals.

Baking soda

Baking soda is a versatile and affordable household ingredient that can be used to absorb odors. Its natural properties work by neutralizing and eliminating unpleasant smells. Baking soda is also non-toxic, making it a safe option for cribs.

Activated charcoal

Activated charcoal is another effective natural deodorizer. It works by adsorbing odor-causing molecules, trapping them within its porous structure. Like baking soda, activated charcoal is safe to use around babies and can be easily obtained.

White vinegar

White vinegar is a multipurpose household item with deodorizing properties. Its acidic nature helps eliminate odors and inhibit the growth of mold and mildew. Vinegar is also safe to use around babies, given that it is properly diluted.

Essential oils

Essential oils not only provide pleasant fragrances but also possess antimicrobial properties that can help combat musty odors. However, caution should be exercised when using essential oils around babies, as some oils can be irritating or harmful when not used properly. Always follow the recommended dilutions and consult a healthcare professional if unsure.

Using baking soda to deodorize a musty crib mattress

Baking soda is an excellent choice for deodorizing musty crib mattresses due to its simplicity and effectiveness.

Vacuum the mattress

Before applying baking soda, it is essential to thoroughly vacuum the mattress. This helps remove any loose dirt, dust, or debris that may contribute to the musty odor.

Sprinkle baking soda

Once the mattress is clean, sprinkle a generous amount of baking soda evenly over the entire surface. Use enough to cover the mattress without leaving any gaps.

Let it sit

Allow the baking soda to sit on the mattress for several hours. This will give it enough time to absorb the odors.

Vacuum again

After the baking soda has had time to work its magic, carefully vacuum the mattress once more. Make sure to use a clean attachment to avoid reintroducing any dirt or dust particles.

Deodorizing with activated charcoal

Activated charcoal is an excellent option for deodorizing musty crib mattresses. Its porous structure helps absorb and trap odors effectively.

Place charcoal near the mattress

To use activated charcoal, simply place a container or pouch near the crib mattress. Ensure that it is within close proximity to allow for maximum odor absorption.

Wait for odor absorption

Allow the activated charcoal to absorb the musty odors over time. The duration will depend on the severity of the odor. Check the container periodically to see if it requires replacement.

Replace charcoal regularly

Activated charcoal has a limited lifespan for odor absorption. It is important to replace the charcoal regularly to ensure continued effectiveness. Follow the manufacturer’s recommendations for proper replacement intervals.

Using white vinegar as a natural deodorizer

White vinegar is an excellent natural deodorizer that can help eliminate musty odors from crib mattresses.

Create a vinegar solution

Dilute white vinegar with water in a 1:1 ratio. This will create a mild vinegar solution that is safe to use on crib mattresses.

Apply the solution to the mattress

Using a clean cloth or spray bottle, apply the vinegar solution to the surface of the crib mattress. Make sure to cover the entire area evenly.

Allow it to air dry

Allow the vinegar solution to air dry naturally. This will give it time to neutralize odors and inhibit the growth of mold or mildew.

Ventilate the room

To help speed up the drying process, open windows or use fans to promote air circulation. This will also help remove any residual vinegar smell.

Deodorizing musty crib mattresses with essential oils

Using essential oils is a natural and aromatic way to deodorize musty crib mattresses. However, it is important to choose the appropriate oil and use it safely.

Choose the appropriate essential oil

Select an essential oil known for its deodorizing properties, such as lavender, tea tree, or lemon. Ensure that the oil is safe for babies and suitable for use on crib mattresses.

Create a spray solution

In a spray bottle, combine several drops of the chosen essential oil with water. The ratio will depend on personal preference, but it is typically around 10-15 drops per 8 ounces of water.

Spray the mattress surface

Lightly mist the crib mattress with the essential oil spray solution. Pay attention to areas that are particularly musty or prone to odor buildup.

Air out the mattress

After spraying, allow the mattress to air out. This will help the essential oil aroma disperse while eliminating musty odors.

Preventive measures to avoid musty crib mattresses

Taking preventive measures can help prevent musty odors from developing in crib mattresses.

Use a waterproof mattress cover

Using a waterproof mattress cover can help protect the crib mattress from spills, leaks, and excessive moisture. This will prevent moisture buildup and reduce the risk of mold or mildew growth.

Properly clean and dry the crib

Regularly clean the crib and ensure that it is completely dry before placing the mattress back in. Remove any potential sources of moisture, such as wet bedding or toys.

Ensure good air circulation

Ensure that the crib mattress has access to good air circulation. Keep the crib away from walls, avoid covering the mattress with impermeable materials, and provide adequate spacing between the crib and other objects.

When to seek professional help

While homemade solutions can effectively address musty odors in most cases, there are situations where professional help may be necessary.

Persistent musty odor

If the musty odor persists even after attempting the homemade solutions, it may indicate a more severe underlying issue. In such cases, it is advisable to consult a professional mattress cleaner or mold remediation specialist.

Visible mold or mildew growth

If there is visible mold or mildew growth on the crib mattress, it is crucial to seek professional help immediately. Mold and mildew can pose significant health risks, particularly to babies and individuals with allergies or respiratory conditions.

Allergy or health concerns

If there are concerns about allergies or health conditions related to the musty odor, it is best to consult a healthcare professional for guidance and appropriate recommendations.


Musty odors in crib mattresses can be effectively addressed with natural deodorizing methods. Whether using baking soda, activated charcoal, white vinegar, or essential oils, it is important to follow the proper steps and take preventive measures to avoid future odors. By maintaining cleanliness, promoting air circulation, and addressing moisture buildup promptly, parents can ensure a fresh and pleasant sleeping environment for their little ones.
