There are two effective options to destroy mould:
1) Sodium Hypochlorite (bleach) solution. Sodium hypochlorite works well at low concentrations and is effective against both mould and mould spores . It is cheap and readily available.
2) Heat treatment (95 degree cycle on a front loader), this cannot be used on PUL/elastics.
*AGAIN, DO NOT PUT SHELLS/AIOs/NAPPIES WITH ELASTICS INTO A 95 DEGREE CYCLE*
See the sanitise instructions on the Strip and Sanitise page for information on using bleach or 95 degree cycle to treat mould.
To remove stains caused by mould, use a Vanish/Napisan type product.
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 or cinnamon oil are only effective against mould at 250ppm  , 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.
