Question

Can Tecnu Original poison ivy cleanser be used sooner than 2 hours after exposure?

Answer

The sooner you remove urushiol from your skin the better as the poison ivy and oak rash is caused by your body's reaction to the bond of the plant's oil to your skin. Everyone's body is different so some people react to urushiol sooner than others  which is why we have a time range on there.  We have found that, for most people, it is best to remove the oil within 2-8 hours of exposure.

Use Tecnu to remove poison ivy and oak oil from skin, pets, tools and equipment
