Sanitise and stain removal for modern cloth nappies and textiles

Our sanitise methods cover ammonia, stain removal, mouldy textiles, prams and wool. We have helped tens of thousands of users worldwide.

We have helped thousands of users worldwide remove stains, smells and ammonia. Our sanitise and stain removal information covers modern cloth nappies, PUL, mouldy textiles, prams and wool. Our team of qualified chemists developed and tested these methods, and we are constantly improving them.

Say goodbye to strip-washing

Stripping, strip washes, and strip soaks—no matter what you call them—are not effective cleaning methods. All in all, a ā€˜strip wash’ is either just washing or soaking. You can get the same, or better, results using a long warm/ hot wash with detergent and laundry booster in your washing machine.

We no longer recommend strip washing prior to sanitising nappies or textiles. Instead, we recommend a short wash to remove soiling (poo, wee, blood, food).

If you are sanitising your own nappies, wash them first. A nappy first wash is sufficient. If you are sanitising second-hand nappies and they are not visibly physically soiled there is no need to wash them first.

Reasons to Sanitiseā„¢ cloth nappies

Sanitisation removes ammonia and any microbes that can cause problems like redness, rashes and fabric degradation.

Even with the best wash routine and washing machine, cloth nappies and diapers can smell and get stained (after all, their job is to catch poo and urine). The good news is it is easy to fix and get them back to stain-free, and smelling great.

Reasons to sanitise include:

  • Second-hand purchases
  • Washing nappies in cold water
  • Using a less-than-great detergent
  • Smells, stinks and stains
  • Mould
  • Nappy rash or redness
  • Fungal infections
  • Bacterial infections

Sanitising within an early childhood education centre

You may also need to sanitise cloth nappies and diapers shared among non-siblings, such as in an early childhood education centre or family daycare setting. Learn more about our single-cycle protocol.

Our sanitise methods

Our original chlorine bleach calculator has 26 31 different options to choose from, including ammonia smells (mild, moderate, significant), cold water washes, mould (minor, moderate and significant), single cycle nappy washes, second-hand nappies, minor stains, major stains, bacterial infections (Staphylococcus, Impetigo, Salmonella, Listeria), fungal infections and more.

After we launched our revolutionary sanitise calculator in 2020 our members asked for specialist advice on mouldy textiles and cleaning prams. We created stand-alone calculators to cater to these situations.

Stovetop sanitise

Stovetop sanitising is appropriate for delicate items that need sanitising but cannot tolerate high heat or chlorine bleach.

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.

Suitability by fabric
Sanitise method Colours PUL Whites
90/95°C sanitise cycle Not suitable for PUL
Front loader chlorine bleach Not suitable for coloured and noncolourfast fabrics
Top loader chlorine bleach Not suitable for coloured and noncolourfast fabrics
Small scale chlorine bleach

*Fabric may fade or shrink, and prints and decals may crack or peel during a 90/95°C sanitise cycle. If you are unsure how the item will react to heat use the Small Scale chlorine bleach method instead.

†Use the non-colourfast option for natural fibres, or natural fibre blends, that are coloured or dyed (for example cotton or bamboo). Other options use a higher concentration of chlorine bleach and may result in those fabrics fading.
