How long does urushiol last? Do I need to clean urushiol oil from clothing and tools?

Yes, removing poison ivy oil from tools and equipment is important to avoid a rash through secondary contamination. Urushiol can stay on these items for a long time, possibly years, causing a rash when you come in contact with them the next time.

An effective way to remove poison ivy or oak oil from these items is to use Tecnu Original Outdoor Skin Cleanser. Just wipe on the cleanser and then remove with a cloth or rinse off with water. Be sure to follow the directions on the bottle. It is also important to remove urushiol from your clothing, shoes and your pet's fur if they come in contact with the plants.
