When I think of mold I always think of a time in college when I was watching
a friend clean our dorm showers.  I saw all the mold on the walls and I
thought how hard of a job it would be to clean all of that mold off of the
walls.  My friend was an old hand at cleaning showers and just sprayed the
walls with a solution and the mold vanished.  I was shocked and asked him
what the stuff was.  Just bleach and water. Simple yet effective.
You don't think a mouse could've gotten in your heater system do you?  They
can leave bad stuff behind too.
