Post fire and flood cleaning of goods and spaces

Generally speaking, furniture and goods under the soot line in a room where a fire took place are damaged only by the contact with black smoke. Therefore, they require a thorough post fire cleaning that cannot be carried out with common chemical detergents. To evaluate the possibility of a reconditioning, it is necessary to remove objects and possible protections to see if there are differences between damaged and non-damaged areas. It is also important to check the inside of the pieces of furniture for possible smoke infiltration. Permanent color differences must be checked through a cleaning test: outside surfaces can be manually cleaned with a diluted alkaline detergent, while inside or hidden surfaces may require scraping. When evaluating the possibility of reconditioning tissues, coverings and carpets damaged by water or fire, it is necessary to differentiate the materials that compose them.

Natural fibers, both animal and vegetable, react differently to damaging elements and reconditioning techniques. So do chemical fibers like nylon, polyester etc. Synthetic fibers, for example, have a very low resistance to heat, and melt between 163°C and 260°C. They also tend to gather and keep soot particles and the consequent foul smell. On the contrary, their resistance to water is way higher than that of natural fibers. Odor control and a washing technique that works for the specific textile fiber is the first and most immediate recovering method. In the event of particularly delicate damages like water damages to carpet colors, it is necessary to act immediately to prevent different colors to mix, which would result in a loss of value for the entire good.
