If you were exposed to poison ivy which of the treatments below would you apply to the affected area to make this offending chemical most soluble so to be washed away?

Don't burn poison ivy or related plants because the urushiol can be carried by the smoke. Wash your skin or your pet's fur. Within 30 minutes after exposure, use soap and water to gently wash off the harmful resin from your skin. Scrub under your fingernails too (i got this on google)
