I just wondered what they used to clean up the
cloths afterwards.

When I was clearing Poison Ivy, I just put the clothes in the washer
and dryer. The combination of detergent in the washer and heat from
the dryer is enough to neutralize the stuff. After removing the
clothes from the dryer, there will be black marks where the clothes
came in contact with the ivy. My jeans and shirts looked like I
had attacked them with a black permanent marker.
