Acidic soot residue starts corroding unprotected metal within roughly two days in Lawrence Township, NJ conditions, which is why classification happens fast, not as a leisurely first step.

Treating both classes the same way is the most common soot-cleanup mistake.
Dry-chemical sponges for porous materials, solvent agents for non-porous ones.
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.
HEPA extraction pulls particulate before any wet cleaning ever touches the fiber.
A completely different chemistry than what porous drywall responds to.
Acidic residue neutralized on faucets, hinges, and hardware before pitting starts.
Ceilings get worked before walls so falling particulate doesn't recontaminate finished surfaces below.
A property can look clean and still be recirculating particulate through the ducts.

No return trip needed once the surface classification is done.
You see the plan split by surface class before approving anything.
The job isn't finished until every classified surface has been addressed.
"Learning that porous and non-porous surfaces get treated completely differently was new information, but it made sense once explained." — Homeowner, Lawrence Township
"Fast response on the metal fixtures meant we avoided the corrosion damage a slower crew might have missed." — Homeowner, Lawrence Township, NJ
"Watching them vacuum the carpet before doing anything wet made sense once they explained wetting soot-loaded fiber just sets the stain." — Homeowner, Lawrence Township
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.
Cleaning reduces odor, but persistent smell sometimes needs a separate treatment.
Yes, as long as HEPA extraction happens before any wet cleaning step.
Our Soot Cleanup crews cover Lawrence Township and the surrounding zip codes, carrying tools for both surface tracks on every truck.
