Mould and mildew are not only ugly, they can be a health hazard. When breathed in, the spores can cause chronic cough, nasal decongestant and sinus headaches. Severe sufferers can have difficulty breathing, resulting in a life threatening condition. Mould in the bedroom is especially hazardous because you spend your sleeping hours exposed to it. It is important to remove mould and mildew immediately.

  1. 1

    Create a mixture of 118 ml (1/2 cup) bleach, 79 ml (1/3 cup) washing powder and 3.8 litres (1 gallon) of hot water. Fill a spray bottle with the mixture.

  2. 2

    Put on rubber gloves and a dust mask. Mould and mildew release spores, which you don't want to breathe in, when disturbed. Open windows to ventilate the room to reduce your exposure to bleach fumes.

  3. 3

    Spray the mould with the solution, working from the top of the wall down.

  4. 4

    Gently scrub the mould off with a plastic scrub sponge. If the mould is on the ceiling, skip the spray bottle and scrub with mixture directly out of a bucket.

  5. 5

    Rinse the area with clean water and let it dry.


  1. 1

    Vacuum furniture to remove any loose mould spores.

  2. 2

    Mix 79 ml (1/3 cup) of washing powder into 3.8 litre (1 gallon) of hot water. Do not use bleach in this mixture as it may strip colour out of upholstery and finishes.

  3. 3

    Scrub the affected areas of the furniture with the soapy water using a scrub brush.

  4. 4

    Rinse the furniture with clean water and allow it to dry.

Tips and warnings

  • Commercial mould and mildew cleaning solutions are available for purchase if you don't want to make your own.
  • Consider installing a dehumidifier in the room to keep mould from returning. The humidity level of the room should be 50 per cent or lower to discourage mould and mildew.
  • You can also paint the room with paint containing an anti-mold agent if this is a regular problem.
  • Be careful not to let the cleaning solution (which contains bleach) drip onto carpeting or fabric.
