Overview
Chlorine bleach oxidises and removes certain stains easily. The Clean Cloth Nappies™ Sanitise chlorine bleach table provides the correct quantities to use for 31 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.

Sanitise quick reference tables
Use these quick reference tables to determine which method (or methods) is suitable to sanitise your items.
Note: some options output the same bleach concentration. In this situation there is no need to run separate wash cycles. For example, the Second-hand nappies (unstained/ don’t smell) option is suitable for PUL covers, AIOs and inserts.
