To care for your wool you simply let it dry between changes (if it even got wet) and then use with your next diaper change.
Interlock wool – you can wash interlock wool in your machine (yes, in your machine!) and they do make wool washes but I myself us Tide original which is perfectly safe for the wool. However do NOT dry it in the dryer. You will want to hang dry it. Usually after a washing you will want to lanolize, though you don’t have to every time. How will you know when to wash? Great question. As a rule of thumb I wash 1x a month, unless the wool smells like urine after it is dry (or gets pooped on) then I will wash sooner.
Knit wool - DO NOT MACHINE WASH. You would just add wool wash or baby soap to your lanolizing routine (which is the same as below). Drying process is the same also.
I put solid lanolin in the bottom of my sink and run scalding hot water until it is melted, then I put in enough water to make the sink bath, room temperature. Then you turn your wool inside out, push it down under, give it a few squishes to get the lanolin especially in the wet zone, and then let it soak! Let it soak for at least 15 minutes but I let it soak as long as overnight. When it's done soaking drain the sink, squish out the water, DO NOT WRING, DO NOT RINSE OFF. Lie the wool flat on a towel and roll it up in the towel to get out access water, and then lay flat to dry. It will take about 2 days to get totally dry.
