There's used to be a product out called "Tech Nu" or Technu, something like that. It was a wash that you could use right after coming in contact with the stuff. I think if you washed with this stuff witin a few hours of contacting the poison, it would help to break up the oils. When I was a summer laborer for a power plant in college, they made us kids use it while trimming weeds and stuff. The kids who got it bad, didn't get it so bad after using this stuff. Just a couple spots on the hands and that was it.

Hey, you gotta stay away from the fuzzy vines... You can get poison all year 'round.
