Mould and mildew grow best in warm, moist places such as bathrooms, laundries and kitchens.
In our house, we have an arrangement that the last person to use the shower and hand basin at night, has the pleasure of wiping them out with a towel. This means there is no water left lying around, nor is there a build-up of soap scum, bacteria, mould or yucky things like hair! Damp towels are hung outside to dry or pegged on a sunny back verandah.
The kitchen and laundry sinks are also wiped over with a dry cloth every evening or morning. These are simple routines that greatly reduce the problem of mould and mildew and are easily shared between members of our household.
