I remember an article I read in a book or on line, don't remember which, but do remember that it was written in the late 1800 or early 1900. That suggested wearing your kilt in the rain, a river, or the ocean to clean it, and to wear it until it was dry, by doing this it hold it's size and shape better. Also don't use any soap or soap like product it take the lanolin out of the fibers, which will make the fabric feel ruff and cause shrinkage, just cold water and/or a table spoon of baking soda to a gallon of water, the baking soda will help remove any odors but doesn't remove the lanolin.
