Re: The devils foam
Take it outside (Wearing elbow length gloves and a full face mask), put it in the gutter, point a fire hose at it. After getting most of it out, give it a good dunking in a bucket with some green/yellow/brown soap (Can't find the english name for it. The Dutch and German name translates to " Green soap") to get the rest. Should be good enough to dispose of after that.
