I wash with a bit of mild hand soap, then rinse, then lanolize in a second rinse. To lanolize, I use lasinoh. I put about 1/2 inch per pant in a measuring cup, add about a cup of water, and microwave it for 1-2 minutes to melt the lanolin. The I add a drop of the same hand soap to the measuring cup and wisk it with a fork. The liquid should look milky with no obvious yellow globs of melted lanolin, the soap helps to break up the fat. Then I pour it in the rinse water with the pants (inside out so the lanolin is mostly on the inside), squish them around, remove and squeeze the water out gently. I usually spin the water out in the washer spin cycle, one without additional rinse water added, turned right side out again. Then I lay them on the dryer to dry.
Isn't merino nice?
