Question

Why do I need to rinse with cool running water after rubbing tecnu exreme. for 15 seconds

Answer

Cool water is recommended for the first wash with Tecnu Extreme™ so that the chances of your pores opening up, and absorbing the rash-causing oil, urushiol are lessened. Cool water keeps pores closed, while warm/hot water opens them up.
