Aqua fresh is a bio degradable liquid laundry detergent that removes the oils 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 (Power fresh is in powder form for stubborn stains) to remove the oils from your linen.
