Actually if enzymes really are the problem baking in the sun *might*
help instead of hurt.  Enzymes are proteins and if they get
overheated they change their physical shape and while chemically
unchanged no longer function as enzymes.

I also wasn't able to find any duckduckgo-accessible or wikipedia
mention of egg yolk enzymes.  That doesn't mean they don't
exist.   However there's a story from last August from some little
one-horse town called Bend OR which suggests that sulphur may be the
culprit, and gives some cleaning ideas as
well.
