To effectively get mold out of your clothes, begin by shaking off any loose spores outside to prevent spreading. Pre-treat the affected areas with natural solutions such as white vinegar or baking soda, which help break down mold. Soak the clothes in a mixture of vinegar and water for at least an hour, then wash them in hot water with a quality detergent. After washing, hang the clothes to dry in direct sunlight, as UV rays help kill lingering mold spores.
To prevent future mold growth, always store clothes in a cool, dry place and ensure they are completely dry before storing them.
What causes mold to grow on clothes
Mold thrives in warm, damp, and poorly ventilated environments. Clothes, especially those made of natural fibers like cotton, wool, and linen, are susceptible to mold growth when they are left damp for long periods.
Common causes of mold on clothes include:
- Wet laundry left sitting too long: Clothes left in a laundry basket or washing machine after a wash cycle can develop mold. Mold can start growing in as little as 24 to 48 hours if moisture is present.
- High humidity areas: Closets, basements, and other poorly ventilated spaces can have high humidity levels, making them ideal environments for mold to form.
- Improper drying: Clothes that are not fully dried before being put away can harbor moisture deep in the fabric, creating conditions for mold spores to thrive.
Mold grows by feeding on organic materials, so natural fabrics are particularly vulnerable. However, synthetic materials like polyester and nylon can also be affected, especially if mixed with sweat or organic dirt that serves as food for mold.
Signs of mold on clothes
Recognizing mold on your clothes early can prevent further damage.
Mold is often more noticeable on lighter fabrics, but it can still thrive on darker ones as well. Here are the main signs of mold growth:
- Musty smell: A strong, musty odor is one of the most obvious signs of mold. Even if you can't see the mold, this scent indicates the presence of fungal spores.
- Discolored spots: Mold often appears as black, white, green, or gray spots on fabrics. These spots may look fuzzy or slimy, depending on the type of mold.
- Fabric degradation: Over time, mold can weaken the fibers of your clothes, making them more prone to tearing and damage. This degradation can happen faster in more delicate fabrics like silk or wool.
Mold isn’t just unsightly—it’s also harmful to your health. Exposure to mold can cause respiratory issues, allergic reactions, and skin irritations, making it essential to address the issue immediately.
How to safely remove mold spores from clothes
Before tackling the stains or odors left by mold, you need to remove any loose mold spores from the clothing.
Mold spores can spread easily, so it’s important to take precautions when handling moldy garments.
- Take clothes outside: Mold spores are light and can easily become airborne. To prevent them from spreading inside your home, always take moldy clothes outdoors before cleaning them.
- Shake out the clothes: Gently shake or beat the clothes to dislodge loose mold spores. Make sure to stand upwind so you don’t inhale the spores.
- Brush off visible mold: Use a soft brush to gently scrape off any visible mold spots. Be sure to wear a mask and gloves while handling moldy clothes to protect yourself from coming into direct contact with the spores.
Once the loose spores are removed, it’s time to move on to pre-treating the affected areas.
Pre-treating mold stains
There are a number of effective natural and chemical methods to pre-treat mold stains on clothes.
Below are the most commonly used solutions, ranging from eco-friendly to stronger commercial options.
White vinegar
White vinegar is one of the best natural cleaners for mold. Its acidic properties help kill mold spores and prevent them from returning.
- How to use vinegar: Mix equal parts white vinegar and water in a spray bottle or basin. Spray the vinegar solution directly onto the moldy areas or soak the entire garment in the solution for 1–2 hours. Vinegar is safe for most fabrics, but always test a small patch if you’re unsure.
Baking soda
Baking soda is a gentle yet effective way to treat mold. It’s particularly good at neutralizing the musty odor that mold leaves behind.
- How to use baking soda: Make a paste of baking soda and water, then apply it to the moldy areas. Let it sit for 30 minutes to an hour before washing the clothes. You can also add half a cup of baking soda to your washing machine during the wash cycle for extra deodorizing power.
Lemon juice and salt
Lemon juice, combined with salt, is a natural bleach that can effectively remove mold stains and odors from clothing. Be cautious, though, as this method may cause fading on dark fabrics.
- How to use lemon juice and salt: Squeeze fresh lemon juice onto the moldy areas, then sprinkle salt over the top. Allow the mixture to sit for an hour, preferably in the sun, which helps activate the bleaching properties of the lemon. Rinse well and wash as usual.
Hydrogen peroxide
Hydrogen peroxide is a strong oxidizer and can effectively kill mold on clothes. It works best on white or light-colored fabrics since it can have a bleaching effect.
- How to use hydrogen peroxide: Apply 3% hydrogen peroxide directly to the moldy spots. Let it sit for 10 minutes, then scrub the area gently with a soft brush. Rinse the fabric thoroughly before washing.
Commercial mold removers
If the mold problem is severe, commercial mold removers are available for use on fabrics.
These products contain strong chemicals that are designed to kill mold and remove stains effectively.
- How to use commercial mold removers: Follow the instructions on the label, as these products may vary in strength. Most require you to apply the solution to the moldy area, let it sit for a specified time, and then wash the garment thoroughly.
How to wash moldy clothes effectively
After pre-treating the mold stains, it’s essential to wash your clothes properly to remove any remaining spores and stains.
Washing in the right way is key to ensuring all traces of mold are eliminated.
Washing in hot water
Mold spores can survive in cooler temperatures, so washing your clothes in hot water (above 140°F or 60°C) is crucial for killing them. Always check the care label to ensure the garment can handle high temperatures without shrinking or being damaged.
Using a powerful detergent
For best results, use a detergent designed to combat mold and mildew. Detergents containing enzymes are particularly effective at breaking down mold spores. You can also add a natural mold-fighting additive, like tea tree oil, vinegar, or hydrogen peroxide, to the wash cycle for extra cleaning power.
Adding mold-fighting additives
For heavily mold-affected garments, adding mold-fighting additives to the wash can make a big difference. Tea tree oil, for example, has strong antifungal properties and can be added to the wash (about 10 drops) to kill any remaining spores. Oxygen bleach is another powerful mold remover and can be used in place of chlorine bleach for a gentler, non-toxic option.

Drying clothes in sunlight to remove mold
Once your clothes are washed, drying them properly is essential to ensure mold doesn’t return. Sunlight is one of the best natural ways to kill any lingering mold spores.
The UV rays from the sun are powerful mold killers and can help remove any remaining musty odors. Sunlight also has a bleaching effect, which can be beneficial for white or light-colored clothes that have been stained by mold. However, be cautious when drying dark or delicate fabrics in the sun for too long, as this can cause fading.
If outdoor drying isn’t an option, make sure to dry clothes in a well-ventilated space using a dryer or air-drying rack. The key is to ensure that all moisture is eliminated.
Best practices for storing clothes to prevent mold growth
Prevention is key when it comes to keeping mold from returning to your clothes.
Here are some tips to ensure your clothes remain mold-free in the long term:
- Ensure clothes are completely dry before storing: Never store clothes that are even slightly damp, as this can lead to mold growth. Make sure clothes are thoroughly dry after washing or wearing before putting them away.
- Use breathable storage containers: Avoid storing clothes in plastic bags or sealed containers, as these can trap moisture. Instead, opt for breathable cotton garment bags or fabric-lined storage bins.
- Control humidity levels: If you store clothes in a basement, attic, or closet with high humidity, use a dehumidifier to keep the moisture level below 60%. Humidity control is one of the most effective ways to prevent mold growth.
- Use cedar blocks and sachets: Cedar is a natural mold and moth repellent. Placing cedar blocks and sachets in your closet or storage areas can help absorb moisture and keep your clothes mold-free while also preventing pests like moths from damaging your garments. Refresh the cedar by lightly sanding it every few months to maintain its effectiveness.
- Rotate and air out stored clothes: For clothes that are in long-term storage, periodically rotate them and air them out to ensure they remain dry and fresh.
