Yes, OxiClean can help eliminate mildew smell. Its oxygen bleach properties break down the odor-causing molecules in mildew. For best results, soak the affected items in an OxiClean solution before laundering.
Understanding Mildew and Its Odors

What Is Mildew?
Mildew is a type of fungus that is closely related to mold. It appears as a thin, superficial layer of growth accompanied by a musty odor.
Mildew usually manifests in damp or moist environments, often seen in grey or white patches.
Where Mildew Thrives?
Common places where mildew develops include bathrooms, kitchens, basements, and any area with poor ventilation and high humidity.
It loves to settle on organic materials like wood, paper, leather, and textiles.
Conditions Favoring Mildew Growth
Mildew thrives in moist, warm conditions with limited airflow. Dark spaces and surfaces that hold moisture can also encourage its growth.
A lack of sunlight and poor cleaning routines can make these conditions even more favorable for mildew.
Health Risks of Mildew
Exposure to mildew can lead to various health issues, especially for those with allergies or asthma. It can cause coughing, throat irritation, and other respiratory problems.
Identifying the Smell of Mildew
Mildew emits a distinct musty, earthy smell. This odor is a telltale sign of its presence even when it’s not visible.
It can permeate fabric and linger in rooms, making it uncomfortable to be in affected areas.
Effectiveness of OxiClean Against Mildew Odors

Active Ingredients in OxiClean
OxiClean contains sodium percarbonate, a compound that releases hydrogen peroxide when dissolved in water. It is this release of oxygen that helps break down the mildew and its odors.
Chemical Reaction with Mildew
When OxiClean is applied to areas affected by mildew, the sodium percarbonate reacts with water to form hydrogen peroxide.
This reaction targets mildew at the molecular level, breaking down its structure and neutralizing the odor-causing molecules.
OxiClean as a Deodorizer
Aside from its cleaning abilities, OxiClean acts as a powerful deodorizer. It doesn’t just mask odors; it eliminates them by oxidizing the odor-causing bacteria that mildew leaves behind.
Success Stories with OxiClean
Many users have shared their positive experiences with OxiClean for removing mildew odors.
They have found that pre-soaking items or cleaning surfaces with an OxiClean solution restores freshness and eliminates the stubborn musty smell associated with mildew.
Best Practices for Using OxiClean to Remove Mildew Smells

Step-by-Step OxiClean Use
To effectively use OxiClean for mildew odors, start by dissolving the powder in the appropriate amount of water.
Soak the affected items or scrub the solution onto hard surfaces. Allow the solution to penetrate and work for several minutes before rinsing or laundering.
OxiClean Safety Precautions
When using OxiClean, wear gloves to protect your skin and work in a well-ventilated area. Always follow the instructions on the label and never mix OxiClean with other cleaning products, especially those containing chlorine bleach.
Preventing Future Mildew Growth
Prevent mildew by keeping areas dry, using dehumidifiers, and ensuring proper ventilation.
Clean regularly and fix leaks promptly. Sunlight can also be a natural deterrent for mildew growth.
Additional Measures for Mildew Control
Beyond using OxiClean, consider using anti-mildew sprays and keeping surfaces dry. Paints and sealants designed to resist mildew can also be helpful in certain areas of the home.
Maintenance After OxiClean Treatment
After treating an area with OxiClean, maintain cleanliness with regular wiping and drying. Keep an eye out for any signs of mildew returning and address them promptly with another OxiClean treatment if necessary.
FAQs About OxiClean and Mildew Smell
Can OxiClean remove mildew smell from fabrics?
Yes, OxiClean can remove mildew smell from fabrics by breaking down the odor-causing molecules with its oxygen bleach properties.
How do you use OxiClean to eliminate mildew odor?
Soak the affected items in an OxiClean solution prior to laundering for optimal removal of mildew odor.
Is OxiClean safe for all types of fabrics when removing mildew smell?
OxiClean is generally safe for many fabrics, but it’s best to check the care label and do a spot test before treating the entire item.
How long should items be soaked in OxiClean to get rid of mildew smell?
Items should be soaked for at least one hour in an OxiClean solution, although tougher odors may require a longer soak time, up to overnight.
Can OxiClean be used to treat mildew smells on non-washable items?
OxiClean should only be used on washable items. For non-washable items, it’s best to seek alternative treatments that are suitable for the material.
Final Thoughts
OxiClean proves effective in neutralizing mildew odors due to its oxygen bleach properties, which dismantle the molecules responsible for the smell.
To maximize its efficacy, pre-soaking the smelly items in an OxiClean mixture is recommended before proceeding with the regular washing routine.
