TYPES OF SOOT RESIDUES:
Dry Smoke Residues - This type of residue is often dry and chalky and result from rapidly burning, high heat fires.
Wet Smoke Residues - This type of residue is usually gluey and has a strong odor, resulting from low heat, smoldering fires.
Protein Residues - This type of residue has a very powerful odor and leaves a virtually invisible residue that may discolor paints, plastics, varnishes and other surfaces.
Fuel or Oil Residues - This type of residue can be very smeary and the result of grease or furnace fires. Furnace puff backs distribute fuel oil soot.
Other Types of Residues - Tear gas, fingerprint powder, and fire extinguisher residues are some other common types of residues that need professional cleanup.
