Soot and soot-like materials can appear in a home or commercial building for many reasons. These materials may deposit on carpets, walls, plastic objects and other materials, and are often noted around ventilation grilles and electrical outlets. The culprit for this "ghosting" phenomenon may be caused by smoke infiltration or due to activities and materials used within the property... Fires can produce an enormous amount of smoke that can easily infiltrate homes and buildings not directly touched by flames. This smoke is filled with combustion by-products that include soot/black carbon, ash and char. Odors, discoloration and ghosting effects can result when these combustion byproducts are deposited in buildings on surfaces and belongings.
