What method is typically the first step in removing soot residue?

The dry removal method is typically the first step in removing soot residue because it effectively lifts and removes the soot particles from surfaces without using moisture, which can exacerbate smoke damage. This method employs the use of dry cleaning sponges, brushes, or vacuum systems designed to trap and collect soot without spreading it further or causing additional damage to surfaces.

Using a dry method initially is especially important since soot is a fine, dry residue that can easily be dislodged and dispersed. If wet cleaning methods are used too soon, there is a risk of the soot binding to the surfaces more firmly or wicking up through porous materials, complicating the cleaning process. Therefore, starting with a dry removal method allows for effective and efficient soot removal while preserving the integrity of the underlying materials.
