The good news is that you can deal with mould on your own. You don’t need to be an expert or have any special tools or cleaning products to remove it from your walls. Only, a few ingredients that you already use in your daily life can work wonders. Before you find out how to make mould and mildew disappear from your bedroom, you need to know a few necessary information about them.

Mould and mildew: what are they, and why do you find them on walls

They are fungi that develop and thrive in areas with moisture with poor ventilation. Mould develops from airborne spores, while mildew is a type of mould. Specifically, it is a black mould that is more severe and poses health risks. They usually make an appearance on walls due to high moisture levels with no adequate ventilation. The reasons why you see them on walls vary. It might be due to condensation, rising damphigh humidity or pipe leak.

The most common areas in a home you can find mould and mildew are basements, exterior walls, laundry rooms, kitchen, bathrooms, tile grout and bedrooms.

How they affect your health

Anyone with respiratory problems living with spores of mould in the house can have asthma attacks. Yet,  even those who don’t have any health issues should be alerted as inhaling mould is not good for you.  It can cause shortness of breath, wheezing, throat irritation, skin rashes and coughing. It can lead up to chronic lung diseases and even asthma as they can cause allergic reactions. So, you shouldn’t take the appearance of mildew and mould lightly as daily exposure not only can but will cause health problems, especially to:

  • Babies and children
  • Elderly people
  • People with existing skin problems, such as eczema
  • People with respiratory problems, such as allergies and asthma
  • Those with a weakened immune system

What are the signs of mould?

Mould can grow on the ceiling, around tiles, near the floors and the walls. Some signs that can help you understand whether there’s a mould problem in your house or not are:

  • Visible mould spores on the walls
  • Dark tile grout
  • musty or damp smell
  • Cracked and peeling paint
  • Breathing and respiratory issues
  • Allergic reactions
  • Skin irritations

If you notice any of these, act ASAP. Otherwise, mould will spread, and it will be dangerous for both you and your home.

How to clean your bedroom walls from mould

Mould in the bedroom walls is frequent due to high humidity levels and condensation.  Poor ventilation and moisture in the air can lead to mould build-up.

How to keep mould away

Once you’ve removed mould from the walls, you can do some things to prevent future growth of mould. It doesn’t mean you should only take prevention measures just in the bedroom. You have to adopt prevention practices for the entire house as well. For example, having mould problems in another room can lead to mould signs in the bedroom.

Thus, you should:

  • Open windows and doors to let fresh airflow in the house.
  • Run dehumidifiers to absorb excess moisture.
  • Use extractor fans after having a shower to remove as much moisture as possible.
  • Don’t let damp towels and clothes in the bathroom. Dry them quickly.
  • Use a squeegee after every shower to clean the shower door, the mirror and the bathroom walls.
  • Clean the bathroom and the kitchen regularly with disinfecting products and use mould prevention sprays.
  • Avoid drying clothes inside the house. Instead, let them dry in the tumble dryer or hand them outside if possible.
  • Check regularly for water leaks in the bathroom, cabinets and wardrobes.
