The Best Way to Remove Mold From Cotton Fabric

Mold forms and spreads on cotton fabric when it sits in a warm, moist location for a long period of time. Mold on cotton fabric requires immediate removal. When left to continue spreading, mould weakens the cotton fabric, destroying clothing and other textiles. While commercial and chemical products are effective for removing mould from cotton fabric, supplies found at home are equally effective without the chemical exposure.

Take cotton fabric outside to brush visible mould spores off. Use a stiff-bristled brush and brush away from you so mould spores don't land on your clothing.

Launder cotton fabric in the hottest water possible, with washing powder and 1 cup white vinegar. Add the white vinegar to the wash cycle to kill mould spores.

Combine 1/4 cup lemon juice and 1/4 cup salt to make a mould-killing paste. Apply the lemon and salt paste to cotton fabric at the site of any remaining mould stains with an unused paint brush. Place the cotton fabric outside in direct sunlight until dried.

Flush the cotton fabric with warm water to remove the lemon and salt paste. Wash the cotton fabric according to the directions on the care label and dry in the sun.


Sunlight is a natural mould killer and bleaches mould stains. Soak mouldy cotton fabric in a bucket with 1 gallon warm water and 2 cups white vinegar.
