Humidity above 70% invites mould. Use this room-by-room checklist before and during the rainy season.
Bathroom
Squeegee walls after showers, keep the exhaust fan running 20 minutes, re-grout cracked tiles.
Bedroom
Pull furniture 5cm away from external walls to allow air movement; sun-dry mattresses monthly.
Kitchen
Dry the sink area at night and check under-sink pipes for slow leaks.
Wardrobes
Use silica or camphor and never store slightly damp clothes.
If you already see black patches spreading over one square foot, get a professional anti-fungal treatment — surface wiping will not stop it.
