I'm sure this isn't the first time I've done this... but it's the first time i've noticed. I was just out for a ride and took a nice spill right into a patch of poison ivy on the side of the trail. The problem is that it contacted a semi-open wound that I have from last week's ride. Other then the usual Technu treatment (which I'm doing momentarily), is there anything else I should do to clean it??

(great ride btw, found a nice rockgarden about a mile from my house)
