Once you notice mould in your house, remove it as soon as possible to prevent the mould from spreading. Many commercial cleaning products and chemical solutions can remove mould, but first try using household products to save money and get rid of the mould quickly. Baking soda -- also known as bicarbonate of soda -- is often used as a home remedy for removing mould, depending on where the mould is located in your house. Sometimes the mould may need treatment with a mixture of baking soda and vinegar or it may also require an application of borax to eradicate it successfully.

  1. 1

    Apply 5 ml (1 tsp) baking soda to a cloth that has been soaked in water. Remove mould from walls by thoroughly cleaning the area with the damp cloth and baking soda. Wear latex or rubber gloves when doing this to avoid contact with the mould.

  2. 2

    Pour 125 ml (1/2 cup) of baking soda down your kitchen sink plughole to remove mould from the inside of the pipe. Add 250 ml (1 cup) of vinegar and then plug the drain. Let the mixture sit in the drain for at least 20 minutes. Run tap water down the plughole to clean out the mixture.

  3. 3

    Sprinkle baking soda over a carpet that contains mould. Allow the baking soda to sit on the carpet for an hour or more, and keep children and pets away from the area. Vacuum the area well and the mould should come out.

  4. 4

    Sprinkle baking soda on any mouldy furniture. Scrub the baking soda into the mouldy area using a brush and try to let it sit for at least three days, if possible. Vacuum the area well and the mould should be removed.

  5. 5

    Add at least 125 ml (1/2 cup) of baking soda to your load of washing to successfully remove mould from your clothes. You may need to repeatedly wash it if the mould is not removed the first time and try adding 250 ml (1 cup) of vinegar or 250 ml (1 cup) of borax to the washing in the machine.
