Mould grows in damp and humid environments, especially where there is poor airflow.
Common causes include:

You can remove mould using simple household solutions such as:

Apply the solution directly to the affected area and leave it for 10 to 15 minutes.

Use a soft cloth or brush to clean the mould from the wall.
Avoid aggressive scrubbing, as it may damage paint or plaster.

Moisture is the main reason mould grows, so drying the wall is essential.
