Mould is a living organism and must be killed to remove it.
You can easily and safely wipe away little patches of dark staining around windows and on bathroom tiles. Use a cloth moistened with diluted bleach and throw it away afterwards.
Mould which has spread over large areas of walls or ceilings needs more drastic action. Everyday cleaning products like bleach or washing up liquid will not work here.
You will need to wipe down affected surfaces with a fungicidal wash.
When using a fungicidal wash, follow the manufacturer’s instructions and check that it carries a Health and Safety Executive approved number.
Try to avoid disturbing mould by brushing or vacuuming because this can increase the risk of breathing problems.
You should dry clean clothes that have mould growing on them. Carpets with mould on them should be shampooed.
Once you have treated mould, you can help prevent it coming back by reducing condensation in your home. The only lasting cure for mould is to get rid of moisture.
Damp and mould will affect the appearance of paint and wallpaper and may leave permanent marks.
If this is the case, you will need to redecorate the affected areas. Surfaces will not return to their original condition on their own.
If you need to redecorate, use a good quality fungicidal paint and do not paint or wallpaper over this.
