Cobwebs can withstand automatic dishwashers.
There was spider that had taken up residence in one of my KitchenAid attachments. After throwing it onto the floor to scare him out (and subsequently squashing him), I tossed the whisk attachment in the dishwasher. Once the load was done, the whisk still had remnants of cobweb on it. No longer sticky, but definitely still there. That spider silk is wicked strong (heat & soap resistant) stuff!! :-D
