Fire And Soot Webs
After a fire, you may look around your home and see black webs hanging from the corners. You may even think that they are spider webs that were already there and caught some of the soot. But don't worry, it doesn't mean you are a bad housekeeper.
In fact, those aren't spider webs at all. What you are seeing are called soot webs. Soot webs form when petroleum-based products in your home burn during a fire. The sticky soot rises and clings to the corners of your home and are a sure sign that smoke did enter the room in which you find them.
