How to Clean Soot Off Walls in Miami
To clean soot off walls, start dry, work from the floor up and stop if the soot smears. Miami homes are mostly painted block and stucco, which hold soot differently from drywall. This guide says what is safe for an owner to try and what is not.
How to clean soot off walls with dry methods first
Open windows and wear a dust mask and eye protection. Vacuum loose soot with a brush attachment, then lift what remains with a dry chemical sponge. Use straight strokes and turn the sponge as it dirties. Do not wet the wall first. Water and household cleaners push oily soot into the paint, which a Miami restoration firm's guidance for homeowners says plainly. Clean from the floor up, the booklet advises, so dirty runs do not streak a clean area.
Clean soot off walls of block and stucco
Stucco and unpainted block are porous. Guides for stucco warn against acid cleaners and chlorine, which can stain it permanently, and recommend an oxygen-based cleaner after a dry brush-down, tested on a small hidden patch. On brick and masonry, wipe rather than scrub, because scrubbing drives soot deeper. The US General Services Administration describes poultices for stubborn smoke stains on concrete.
When to stop and not clean soot off walls yourself
Stop if the soot is oily, if it covers more than one wall, if it smells strongly, or if a sponge leaves a smear. A grease fire or a plastic fire leaves a residue a household sponge cannot lift. Soot is also a health irritant; one Miami restoration firm advises seeking medical attention for coughing or breathing trouble and avoiding contact until the area is cleaned. Check the ducts too. The county booklet says to have a licensed air conditioning company inspect the unit and ducts for soot.
Which walls need a crew when you clean soot off walls
Ceilings, textured walls, kitchen walls with grease, and any room beyond the burn need a crew with HEPA vacuums and tested methods. The cost of a failed DIY is repainting, and a smear can turn a cleanable wall into one that needs primer.

Dry brush first, then an oxygen-based cleaner on a test patch. Avoid acid and chlorine.

Stop. A smear means the soot is oily, and continuing makes it worse. Call a crew.
