Apply Tecnu directly and rub until the stain dissolves. Rinse off with soap and water. The Tecnu Story: Poison oak, ivy and nuclear fallout. Tecnu was developed in 1961 during the cold war by chemical engineer, Dr. Robert Smith, as an effective waterless cleanser capable of removing radioactive dust from the skin and clothing. His wife accidentally discovered that Tecnu would cleanse poison plant oils after exposure to poison oak and ivy. Tecnu has become standard-issue in first aid kits of outdoor professionals across the country. Now, you can put Tecnu to work for your family.
