Mildew and Mould

Mix one part hydrogen peroxide with two parts water in a spray bottle. Use the hydrogen peroxide thats available at the supermarket. Spray the ceiling and leave to dry for an hour then rinse the areas off.

Otherwise you could sponge undiluted white vinegar on and leave it.

You could also try dissolving half a cup of vinegar with half a cup of borax in warm water and sponging that onto the mildew and mould.
