Start by testing a small and discrete area on the fabric with a dab of common laundry soap and cold water to clean, if all is fine and well (which should be), then throw into washing machine on a gently cycle clean with cold water. Lay flat hang until dry. If some wrinkling does occur, use handheld steamer to clean up the final touch.
