So many trails, so little time for itchy problems, right? Tecnu® Original Outdoor Skin cleanser is a poison ivy wash designed to remove the rash-causing oil (urushiol) from your skin (and other items) after exposure to poison ivy, poison oak, & poison sumac plants.

Product Description

If you know, or think you have been, exposed to poison ivy plants (or, poison oak & sumac): apply Tecnu to dry skin, rub vigorously for two minutes, then rinse with cool water. If you do not have access to water, you can remove Tecnu with a cloth.

The magic rule with Tecnu and poison ivy oil is, the sooner you wash the better! Wash within 8 hours for your best chance to avoid a poison ivy rash. After 8 hours, the likelihood of developing a rash drastically increases. Remember, even if you do break out, wash with Tecnu to remove an excess oil that may be on the skin; this will keep the oil from spreading to other areas.

Don't be fooled by the power of urushiol, the resin from poison ivy (oak & sumac plants) is incredibly potent and lasts for months, even years on certain items. If you touch something that has been contaminated with urushiol, you can develop a rash. Therefore, we recommend cleaning items that could be contaminated, with Tecnu Original to avoid secondary contact. For more on how to use Tecnu, and what you can use it on, visit this page.

Fun fact: The name "Tecnu" was given by its inventor (Doctor Robert Smith), meaning "technically new"; you have likely seen it misspelled as Tech Nu or Technu Outdoor Skin Cleanser.
