Dehumidifiers may be used if available. Do not store firewood indoors. Make sure water pans below self-defrosting refrigerators are frequently emptied.
Tumble dryers can also increase indoor humidity and promote mould growth.
Rubbish bins should be emptied and cleaned frequently. The Bathroom Open all windows after showering or bathing. Wash down shower curtains, tiles, shower cubicle, bath and ceiling with household bleaches such as Jik or Milton which kill moulds. Do not carpet the bathroom. Air all cupboards frequently.
