You may take down alternative products to a professional dry cleaner or wash them at home.  We strongly suggest taking it to a commercial dry cleaner that is comfortable cleaning down alternative products.  If washing at home, was your down alternative pillow in warm water (alone in a non-agitator machine) and then tumble dry on low heat (again, alone). Keep in mind, the drying process may take all day!  Made in USA.
