If you happen to get any oils on your skin from the poison ivy, try this to get it off quickly. Pour some straight bleach on the skin area - hands or arms - and then you will see the oil turn dark brown - then scrub the brown stain off with fels naptha soap - gardening soap - until the oils are gone. I've done this a number of time when I got into some poison ivy unexpectedly. Knock on wood, I haven't developed a rash when using this treatment.
