Unlike washing powder, Ariel washing liquid gets to work right at the heart of the wash, for perfectly clean laundry pour some liquid on a stain, spread and scrub with the pre treat cap, and put your clothes in your washing machine. For best results, insert the cap filled with the detergent into the washing machine drum. For an extra boost of freshness and softness, use together with Lenor fabric conditioners and Unstoppables. 60 washes based on 50ml per wash.
