If I can help it, I try not to use soap or detergent. ie I don't wash dishes the night I am planning tank maintenance or a frag sale.
if there is nothing on my hands, just hot water and wringing of hands and forearms before wipe down with clean towel.
if there is something on my hands, anti bacterial hand soap with hot water rinse.
I just high pressure rinse my ocassional sock use down with gardne hose, but I have heard people just wash them with home machine.
