After washing wool diaper covers / soakers you will need to add lanolin to the wool diaper again, or to lanolize the wool like it is called. Most common way to add lanolin to your wool is to do a lanolin soak.
Nursing pads and mittens can also benefit from lanolizing, to make them water resistant and for the moisturizing and skin friendly effect of the lanolin.
People who are allergic to wool may want to avoid Lanolin, as that is considered to be responsible for most wool allergies.
To lanolize your will need
Lanolin (about 1 tsp per cover)
Wool wash
A cup of boiling water
A laundry sink or bowl of warm water to soak your wool in
Wool cover
Always start with clean wool
Turn your wool cover inside out.
Fill your bowl or sink with lukewarm water.
Add lanolin to the cup of boiling water and stir to dissolve the lanoline.
Add a tsp of woolwash to the cup, and stir until the mixture is milky and there are no visible clumps of lanolin. You might need to add a little more soap, depending on what soap you use to emulsify the lanolin. If you prefer to use a bar of soap to emulsify, simply just dip the soap into the cup and stir until the mixture is milky.
Now add the lanolin & soap mixture in the bowl of lukewarm water, stir a little bit to mix.
Add your woolies and let them sit for a while. Do not agitate to prevent felting, let the cover sit there until the water has reached room temperature. You can let it soak for a couple of hours or overnight.
After lanolizing your wool, carefully squeeze out most of the water. Be mindful not to stretch or distort them. Do not twist or wring your wool items.
Lay them flat to dry, they will need time and space to air dry. Pointing a box fan towards them can cut drying time.
Allow your wool soakers to dry completely before use.
