Chlorine bleach sanitise for cloth nappies

Remove stains and smells from cloth nappies, diapers, clothes and general laundry with our chlorine bleach calculator.

Chlorine bleach is cheap, readily available, effective, easy and environmentally friendly. You can use chlorine bleach in a bucket, front loader or top loader washing machine.


Chlorine bleach oxidises and removes certain stains easily. The Clean Cloth Nappies™ Sanitise chlorine bleach table provides the correct quantities to use for 27 different options.

Unsure what method to use? We have a gallery, quick reference matrix and an application and problem glossary to assist in choosing the correct sanitise option.

Depending on your electricity cost, sanitising with chlorine bleach may be less expensive than running a 90/95°C sanitise cycle.
