Wet smoke

Professional requiredThis page explains the work. It does not tell you how to do it, because doing it without training and equipment is unsafe.

Smoke type: Wet smoke

Sticky, smeary, dense. Webs in corners. Strong, persistent odor.

It smears under pressure, so dry wiping drives it into the finish and turns a cleanable surface into a refinishing line item.

Low-heat, smouldering fires with plastics and rubber. Sticky, smeary, dense. Webs in corners. Strong, persistent odor. It smears under pressure, so dry wiping drives it into the finish and turns a cleanable surface into a refinishing line item. The distinction matters because it changes what the work actually is, and therefore what it costs.

Why this needs a professional

This page describes the residue. It contains no cleaning procedure, because the wrong method on this residue turns a recoverable surface into a refinishing job, and that damage is immediate and irreversible.

What comes next

A structure fire also brought suppression water, which is rarely Category 1 by the time anyone can get in. See water categories, and past the drying window, mold.

Guidance that does not name a water category, a smoke type, or the peril and whether the water was internal or external is not specific enough to act on. This page names them.
