Rinse throughly with warm water. Shake out the excess water and hang tail(s) up to dry or lay on a piece of card board. You will find tieing with these really clean tails much more enjoyable to use, as the hair will be softer and have a wonderful feel. The cleaning process also makes stacking the hair easier. Item# 845
