How to Clean Moldy Wool Clothing
Wool is very susceptible to mould and mildew. (macro striped wool image by green 308 from

Wool clothing stored in damp, warm, dim, or poorly circulated areas can easily attract mould and mildew. If permitted to grow, mould can cause considerable damage, sometimes completely ruining the wool clothing. Signs of mildew and mould in wool clothing include an unpleasant musty odour, discolouration, and sometimes holes in the fabric. Mold and mildew should be removed immediately from wool clothing, and preventive measures should be taken to protect your wool clothing from mould.

  1. 1

    Remove the mouldy wool clothing from the house immediately and place it outdoors. Never try to clean mouldy items in your house, as the mould spores can spread from the clothing to other objects in your home and cause further damage.

  2. 2

    Brush off any loose mould growth from the wool with a soft-bristled nylon brush. After the mould is brushed off of the wool clothing, leave the clothing outside in the sunlight for three hours. Sunlight kills mould and mildew.

  3. 3

    Soak the wool clothing in a bucket of cold water for one hour, and then rub a few drops of mild detergent on the mouldy spots. Be sure to use rubber gloves when applying the detergent to the mould. Rinse the spots with water after applying the mild detergent to them.

  4. 4

    Lay the wood clothing flat on a board or table outside to completely dry. The clothing needs to lay flat to prevent it from stretching and losing its shape. The sunlight will kill any remaining mould left on the wool clothing.

Tips and warnings

  • Never use chlorine bleach on wool clothing, as it can damage the wool.
