Treating both classes the same way is the most common soot-cleanup mistake.
Using the wrong tool on either class tends to make the residue worse.
Metal fixtures get attention early since acidic residue starts pitting fast.
Fine particulate captured rather than recirculated back into the air.

Dry-chemical sponge work lifts embedded particulate without pushing it deeper.
Wetting a soot-loaded carpet before vacuuming just sets the stain.
Solvent-based agents lift residue that a dry sponge would just smear across a hard surface.
Acidic residue neutralized on faucets, hinges, and hardware before pitting starts.
Sequencing matters as much as the cleaning technique itself.
Vents and returns cleaned on the same visit since they keep redistributing soot otherwise.

Crews arrive carrying tools for both the porous and non-porous tracks.
Every surface gets classified and priced before any cleaning starts.
The job isn't finished until every classified surface has been addressed.
"I didn't realize our drywall and our tile backsplash needed totally different cleaning approaches until they explained the classification step." — Homeowner, Glen Burnie
"They got to our kitchen faucet fast enough that it never even started pitting, which the adjuster said was lucky timing on our part." — Homeowner, Glen Burnie, MD
"The HEPA extraction step before any wet cleaning turned out to be the reason our carpet actually came clean." — Homeowner, Glen Burnie
Porous materials absorb soot into the surface itself; non-porous ones just hold it on top.
Classification happens before any cleaning tool comes out.
Roughly two days under typical conditions, which is why we prioritize metal early.
Particulate removal and odor treatment are related but distinct services.
Skipping that order is the most common way carpet soot gets set in permanently.
Response times stay short across Glen Burnie specifically because the corrosion window on metal fixtures doesn't wait.
