So... in my 1999 E36, some #$#$ decided to pour a bunch of egg yolk into my windshield cowl, and now I've got dried egg crap splattered on my hood and in the cowl, and a nice rotten eggy smell around my car. I haven't turned it on yet and sucked the egg smell inside, but I'm wondering if anyone had any good ideas of how to neutralize the egg smell, aside from taking out the windshield cowl and cleaning it and the ductwork underneath...
