There are two effective options to destroy mould:

  • Diluted Sodium Hypochlorite (chlorine bleach). Sodium hypochlorite works well at low concentrations and is effective against both mould and mould spores [1]. It is cheap and readily available.
  • 90/95°C degree front loader machine cycle. This option is not suitable for items with elastics or PUL, including covers, AIOs or nappies with elastics.

Mould removal process

The mould removal process is the reverse of the S&S, first sanitise, then remove the stains caused by the mould.


See the sanitise instructions on the Small Scale S&S, Front Loader S&S or Top Loader S&S pages for information on using bleach or 90/95°C cycle to treat mould.

Stain Removal

To remove stains caused by mould, use a laundry booster product such as Vanish. See the instructions listed on the packaging, or the strip process on the S&S pages. Do not apply Vanish or any gel or liquid stain removers directly to PUL as it may delaminate it.

Vinegar and mould removal

4.2% acetic acid is effective against one type of mould, Penicillium chrysogenum, but it has a pH of 2, which is very acidic. This low pH is damaging to fabrics, therefore it is not recommended for use. See this page for more information about Vinegar.

Clove oil and mould removal

Clove oil or cinnamon oil are only effective against mould at 250ppm [2] [3], this information is not labelled, so there is no way to tell what the concentration of the active components (cinnamic aldehyde and/or eugenol) are, and therefore there is no way to ensure that the oil will be effective.
