How to lanolise wool covers

Wool Covers are stretchy shorts that fit over the top of nappies as a water-resistant covering. They are most commonly used over the top of traditional flats/prefolds and fitted nappies but can used over the top of any type of nappy to provide superior leak protection.

Many people think wool covers must take a lot of work but in contrast they are actually extremely easy to care for as they only need to be washed and lanolised every 3-4 weeks (unless soiled).

Lanolin is a naturally occurring oil found on sheeps wool which helps to protect and retain the self cleaning function of the wool fibre. On a wool cover it does the same, helping to neutralise, protect and repel moisture. 

Lanolising a wool cover is actually a really simple process and should be done each time you wash your cover (every 3-4 weeks).

How to Lanolise a Wool Cover

You must wash your wool cover prior to lanolising, no need to dry first. 

Lanolin is cheap and easy to buy online, you can also use Lansinoh, Medela, or Purlan left over from breastfeeding. Look for 100% Lanolin.


Machine wash on a Gentle/Wool Cycle on COLD using wool detergent.
You can choose to hand-wash if you prefer (some wool covers can only be hand washed)
Once washed your cover is ready to be lanolised, no need to dry.


  • Mix 1/2 tsp of lanolin in 1/2 cup boiling water with a little squirt of baby/bodywash
  • Stir until mixture is combined (it may turn milky/emulsified)
  • Add mixture to a small bowl of cool-warm water and mix to combine
  • Submerge wool cover inside out and squeeze to distribute water
  • Leave for 1-2 hours
  • Gently squeeze out excess water and line dry in shade
  • Wash and lanolise every 3-4 weeks unless soiled.



  • Roll cover up in a towel to squeeze out any excess water.
  • Your wool cover may feel a little tacky after lanolising which will disappear after use and is a good sign that it is well lanolised (its actually great for the skin).
