Soot is the acidic residue left when materials burn incompletely. It bonds to surfaces, and the wrong cleaning method — especially water on the wrong residue type — drives it deeper and sets the stain. Professionals test the residue first, then match the method: dry cleaning for powdery soot, wet cleaning for smeary residue, media blasting for heavy char on framing.
Soot is the fine black residue of incomplete combustion — carbon particles mixed with oils and acids, depending on what burned. It's acidic, which is why it etches glass and tarnishes metal over time. The type of soot depends on what burned: wood and paper leave dry, powdery soot; plastics and synthetics leave wet, smeary residue.
Not with a household vacuum — standard filters pass fine soot particles right back into the air, and the vacuum itself can be damaged. Professionals use HEPA-filtered vacuums rated for fine particles. Don't run a household vacuum on soot.
Because the soot was sealed in, not removed. Soot bleeds through ordinary paint — that's the 'ghosting' effect. Proper prep means removing the residue first, then using a stain-blocking primer rated for smoke damage before painting.
Call a restoration pro now — the sooner cleanup starts, the less damage spreads.
