First lets understand what fire is and what it does.
Fire is a rapid oxidation process that releases energy in varying intensities in form of light and heat and often creates smoke.
There are 2 types of fire: Flaming and smoldering
Soot is from the fire and can cause black stains on textiles and other items.
Smoke odor may remain in clothing, upholstered furniture, carpets and draperies unless they are properly deodorized before cleaning
During a fire, smoke can permeate walls and other surfaces and drift through household ducts, where it becomes trapped. If not properly removed, smoke odor reoccurs from time to time, especially during warm or damp weather. BnD uses a process known as thermal fogging. This warm chemical fog penetrates your home and walls just as the fire did neutralizing the smoke odor as it goes.
If the upholstery is washable the next step is for BnD to shampoo the entire surface with dry suds made by beating a handful of dampened detergent.
BnD uses a special degreaser to remove soot from walls and hard surfaces.
