Acidic soot residue starts corroding unprotected metal within roughly two days in Hastings, MN 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.
A standard shop vacuum does the opposite of what's needed here.

Sponges get rotated out constantly since a loaded sponge starts redepositing soot.
HEPA extraction pulls particulate before any wet cleaning ever touches the fiber.
Solvent-based agents lift residue that a dry sponge would just smear across a hard surface.
This track gets prioritized first because the corrosion clock doesn't pause for anything else.
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.
+1-866-484-1409 reaches a live Hastings, MN dispatcher who starts tracking the corrosion clock immediately.
No return trip needed once the surface classification is done.
Every surface gets classified and priced before any cleaning starts.
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, Hastings
"Fast response on the metal fixtures meant we avoided the corrosion damage a slower crew might have missed." — Homeowner, Hastings, MN
"Watching them vacuum the carpet before doing anything wet made sense once they explained wetting soot-loaded fiber just sets the stain." — Homeowner, Hastings
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 Hastings and the surrounding zip codes, carrying tools for both surface tracks on every truck.
