What is the technique used on door or window frames during localized cleaning?

Localized damp cleaning is an effective technique used on door or window frames during the cleaning process after a fire incident. This method involves using a slightly damp cloth or sponge to remove soot, smoke residue, and other contaminants without excessively saturating the materials. The moisture helps to lift the residues from the surface, making it easier to clean without pushing the contaminants further into the material.

Localized cleaning is essential in areas like door and window frames because these surfaces can accumulate significant smoke and soot due to their exposure during a fire. Using localized damp cleaning minimizes the risk of damaging the frames while effectively restoring them to a pre-loss condition. This technique is particularly beneficial for delicate or porous materials that could be harmed by more aggressive cleaning methods.

Other methods, such as dry removal or surface wiping, may not provide the same level of effectiveness in lifting contaminants from the surfaces without causing damage. Mass cleaning generally refers to larger areas and is not typically suited for the careful treatment required in localized situations like frames. Thus, localized damp cleaning is the right choice for this task.
