Boy isn't poison ivy fun?!?! I am just finishing up getting rid of a good batch from two weeks ago. That's usually about how long it takes to get rid of it on your own. I use bleach on paper towels and wipe/rub until the spots are sore and burning a little. Then wash off with dish soap and lukewarm water, pat dry and use Benadryl Lotion (for poison ivy). For your shower use Dawn dish soap or one that says it cuts grease. The bleach I only repeat on spots if it seems like it isn't going away or if more pops up around it. Also doesn't hurt to have a bunch of Benadryl tablets to take to help cut down on the itching feeling.
