Adding lanolin back into wool helps it to repel moisture and not to leak. We recommend using Llamajama 100% Pure Lanolin to lanolize your wool. It is a liquid specifically formulated for wool cloth diapering products. Lanolizing your wool longies or soakers is easy.
Stir ¼ teaspoon into a gallon of clean, tepid water. Soak your Llamajama garment inside out for about ten minutes. To remove excess water gently roll it in a towel. Dry flat out of direct heat and light.
