Mould and mildew

Textiles are particularly susceptible to damage through micro-organism growth. Fungi, bacteria, algae and yeast all survive on textiles. Micro-organism growth is associated with damp conditions at temperatures above 24°C and relative humidity above 50%. Poor circulation and stagnant air exacerbate the problem.

Micro-organisms often start growth on soiled textiles, therefore textiles that are relatively free of dust and food stains are less susceptible to becoming a host.

Identification

Musty odour

Irregular stain often with a powdery surface

Stain colour is often black, grey or white, though it can include many other colours

Prevention & storage

Do not store in basements and other damp places

Do not store in plastic wrapping as this causes condensation to form

Do not store in enclosed and sealed places with little or no air circulation

Store or display at a temperature below 24°C and relative humidity lower than 60%

Ensure adequate ventilation

Caution
In some cases if a textile is badly infested the inhalation of spores can be harmful. Mould can produce toxic chemicals that can cause allergies. Seek advice prior to handling an object.
