Power fresh is a bio degradable powder laundry detergent that removes the oils and stubborn from towels and sheets etc. We have heard of an extreme case where a therapist's house burnt down because they placed there towels in a dryer and the oil was still in the towel. It ignited and there house was burnt to the ground. So either get your Linen laundered professionally or use Aqua fresh or Power fresh (aqua fresh is in liquid form maintaining your linen) to remove the oils from your linen.
