Do you have black stains on your walls after a fire? Those stains are caused by soot released during the fire. From what soot is made up of to where it comes from, we cover all the basics of soot problems.
What Is Black Soot From Fires Made up Of?
Soot is made up of fine black particles when something does not completely burn during a fire. It is mostly made up of carbon but may contain low levels of tar, acids, dust, or carcinogens.
Depending on what is burned in the fire, it can feel dry and powdery or slick and oily. Soot is also ionized, meaning it will stick easily to almost any surface. This makes it extremely difficult to clean.
Where Does Soot Come From?
Soot comes from any fire but is most common when wood, oil, coal, or plastics burn. The flames cause airs drafts, allowing the fine particles to float away before they finish burning. As a result, it can spread much further than the fire itself, causing damage throughout your home.
What Is Different Between Soot and Ash?
Like soot, ash is also made up of mostly carbon and other compounds that did not burn completely during a fire. However, ash particles are much larger than soot and are usually grey or white. They are almost always dry, powdery, or even papery.
What Causes Soot?
