I'm a pro at getting poison ivy and poison oak. I even managed to get it last February. There was a vine of it wrapped around a cherry tree I cut up into logs.
I knew I was going to get it, but worked anyway. Before I moved up here I'd get it from along the banks of a couple rivers I wade fished. I used to stream fish for smallmouth bass quite a bit...
I have been using "Tecnu" brand poison ivy scrub for years.

I have a lot of dried out poison ivy on my arms and legs right now. It looks bad, but I never itch if I use the scrub once or twice a day. I pack it on all of my camping trips just incase...
I also use the Tecnu spray.
I went down to an uncleared portion of my creek, wearing shorts and a sleeveless t-shirt, and dug up 9 shrubs/trees. So I kinda figured I'd get da ivy. I had planned to get them last winter but never got around to it.
I'll give dawn soap a try next time. I'm always open to new remedies, because I'm sure I'll get it again before the year is over.
Oh, and both sides of my face match up again. No more Mickey Rourke look. It was trendy, but didn't last.
