Cloth Diapers: Lanolizing Wool Covers
Its easy to lanolize your wool covers. Heat one cup of water along with 1 teaspoon of lanolin (the same pure lanolin you might be using for nipple cream will work well). Put the mixture in a small container and shake until the lanolin is completely dissolved. Add the mixture to eight cups of warm water. You can use an Ivory soap bar to gently rub out anything needing special attention. Allow to soak for fifteen minutes or so. Swish the cover gently through the water to make sure the lanolin is in the wool. Do not rinse the lanolin out of the wool cover. Roll in a towel to remove excess water and lay the cover flat to dry.
As an alternative to lanolizing, you may choose to handwash your wool covers with a lanolin soap. The type of soap you use may determine how often you have to lanolize. We recommend LANA 20% lanolin soap to wash and lanolize your wool covers at the same time. This is a no-rinse soap and can allow you to go up to three to four weeks between washings.
When is it time to lanolize?
It is probably time to lanolize if you start to notice your wool cover wicking moisture, developing an odor or getting wet to the touch between diaper changes (assuming that the diaper isn't completely saturated).
