How to Get Mould Out of Material: A Comprehensive Guide

Understanding the Problem: What Causes Mould on Fabric?

Mould on clothes and fabric is often a result of excessive moisture. This can be due to damp clothes left in the hamper for too long, wet laundry not properly aired, or high humidity in your living space. Managing moisture is crucial in preventing mould growth.

Essential Supplies You’ll Need

Before you begin the process of removing mould, gather the following supplies:

  • White vinegar
  • Baking soda
  • Lemon juice
  • Sodium percarbonate or hydrogen peroxide
  • Soft brush
  • Mild detergent
  • Airing rack or clothesline
  • Gloves, mask, and protective clothing for safety

Having these items on hand will make the task of eliminating mould much more manageable.

Step-by-Step Guide on How to Get Mould Out of Material

Step 1: Assess the Situation and Ensure Safety

Start by examining the fabric for any apparent mould spots. Identify the material type, as some fabrics require gentler handling than others. If the mould has severely deteriorated the fibres, you might need to consider replacing the item instead of trying to save it. Always wear gloves, a mask, and protective clothing to avoid direct contact with mould spores and prevent inhaling them.

Step 2: Isolate and Brush Off Loose Mould

Isolate the affected items to prevent the spores from spreading to other clothes. Take the mouldy clothes or linens outside and gently brush off as much surface mould as possible using a soft brush. Avoid vigorous brushing, as it can cause the spores to disperse into the air.

Step 3: Pre-Treat with Vinegar or Baking Soda

White Vinegar:
Apply a mixture of equal parts white vinegar and water directly on the mouldy areas. Let it sit for 15-20 minutes to allow the vinegar to penetrate and kill the mould. Vinegar is highly effective due to its anti-fungal properties.

Baking Soda:
Alternatively, you can make a paste with baking soda and water to apply on the mould spots. Mix ½ cup baking soda, ¼ cup water, and ¼ white vinegar to form a paste. Apply the paste to the affected area and let it dry or become crusty before brushing it off with a clean, old toothbrush. Then, machine-wash the clothing item with regular laundry detergent and hot water if suitable for the fabric.

Step 4: Use Hot Water and Laundry Detergent

For machine-washable fabrics, wash the items in the hottest water recommended for their fabric type. High temperatures, around 60° Celsius, can kill most mould species. Use a high-quality detergent and consider adding a cup of baking soda to the wash to enhance the cleaning process and eliminate odors.

Step 5: Lemon and Salt for Stubborn Stains

If mould spots are persistent, make a paste using lemon juice and salt to target specific areas. Apply and let it sit for a short period before washing it out thoroughly. The acidic nature of lemon juice helps to break down tough mould cells, while the salt acts as a mild abrasive.

Step 6: Chemical Options for Severe Cases

For severe mould infestations, you might need to use stronger solutions like sodium percarbonate (oxygen bleach), hydrogen peroxide, or borax. Always conduct a patch test on a hidden area of the fabric to ensure it won’t be damaged, and follow the manufacturer’s instructions to ensure safety.

  • Borax: Soak the mouldy clothing item in a solution of hot water and borax. Add ½ cup powdered borax to enough hot water to submerge the item and let it soak for 20 minutes before washing it in the washing machine with regular laundry detergent and hot water.
  • Bleach: For some fabrics, bleach can be effective but use it cautiously. Pre-soak the clothes in bleach for 30 minutes to one hour before adding them to a normal hot wash. However, bleach can weaken fabric fibers and should be used in a well-ventilated area, never mixed with other chemicals like vinegar.

Step 7: Sun-Dry in Direct Sunlight

After washing, hang the clothes and linens outside to dry in direct sunlight. Sunlight has natural anti-fungal properties and can help kill any remaining mould spores. Avoid using a clothes dryer until you are sure the mould is completely gone, as the heat may set the stains and make mould removal more challenging.

Step 8: Special Treatment for Delicate Fabrics

For delicate fabrics that cannot be washed in hot water, use spot treatments like a mixture of lemon juice and salt or commercial enzyme-based mould removers specifically designed for delicate fabrics. Always follow the instructions provided on the product’s label.

Step 9: Check for Lingering Mould and Repeat if Necessary

After the first round of cleaning, inspect the items for any remaining mould. If you still notice mould stains or smell, repeat the cleaning process until the mould is completely gone.

Additional Tips for Mould Prevention

Once you’ve removed the mould, it’s crucial to prevent it from returning:

  • Dry Clothes Completely: Always dry clothes completely before storing them to prevent moisture buildup.
  • Use a Dehumidifier: In rooms with high humidity levels, use a dehumidifier to keep the air dry.
  • Regularly Clean and Ventilate: Clean and ventilate closets and storage areas regularly to prevent mould growth.
  • Avoid Damp Environments: Keep clothes away from damp basements or stuffy closets, which are ideal environments for mould growth.

By following these steps and implementing preventive measures, you can effectively remove mould from your clothes and fabrics, ensuring they remain fresh, clean, and mold-free.

FAQs for Removing Mould from Material


Q: What is the first step in getting mould out of material?
A: The first step is to take the material outside to prevent mould spores from spreading indoors. You should also brush off any loose mould with a soft bristle brush.


Q: Can I use bleach to remove mould from fabric?
A: Yes, but only on white or color-fast fabrics, as bleach can cause discoloration. Dilute one cup of bleach in a gallon of water and apply it to the affected area.


Q: What natural solutions can I use to remove mould from material?
A: White vinegar and baking soda are effective natural solutions. Spray undiluted vinegar on the mouldy area and let it sit for an hour before washing. Baking soda can be mixed with water to form a paste and applied to the fabric.

Q: Can mould stains be removed after washing?
A: If stains remain after washing, try using a stain remover specifically designed for mould or a paste of baking soda and water, then wash again.


Q: Is it safe to dry mouldy material in the dryer?
A: No, heat can set the stains. Ensure the mould is completely removed before using a dryer. Air dry in direct sunlight if possible, as sunlight can help kill remaining spores.


Q: How can I prevent mould from returning on my materials?
A: Ensure clothes are completely dry before storing and store them in a dry, well-ventilated area. Use moisture absorbers or silica gel in storage spaces to control humidity.


Q: Are there any fabrics that should not be treated with vinegar or bleach?
A: Delicate fabrics like silk or wool may be damaged by vinegar or bleach. It’s best to use gentle, fabric-specific methods or consult a professional cleaner in such cases.
