Room by room

Kitchen: wet-wipe all counters, cabinet faces, and inside cabinets where food is stored; wash exposed dishes and cookware.
Bedrooms: launder all bedding and washable fabrics; HEPA-vacuum mattresses and wet-wipe hard furniture.
Living areas: HEPA-vacuum upholstery and drapes, wet-wipe electronics gently with a barely damp cloth, and clean blinds and sills.
Bathrooms: wet-wipe all surfaces and launder towels and mats.
Floors throughout: HEPA-vacuum carpets slowly, then damp-mop hard floors.

Do not forget these

Wash or replace HVAC filters again after the first round of cleaning.
Clean or replace filters in range hoods and portable air cleaners.
Wipe down the insides of closets and drawers where fine ash settles.
Discard food or open packaging that was exposed to heavy smoke or ash.

What professionals know

What the pros do differently

The single biggest error is dry cleaning of any kind. A broom, a feather duster, a leaf blower, or an ordinary vacuum will send the finest and most harmful particles right back into the air, where they hang for hours and end up in your lungs. Everything is wet-wipe, wet-mop, and HEPA. If a tool cannot trap fine particles, it is making your air worse, not better.

Sequence and airflow matter as much as the products you use. Restoration crews set up negative pressure and run HEPA units continuously so particles are captured as they are disturbed, then they clean top to bottom so gravity works for them. You can mimic this at home by running a HEPA cleaner in the room you are actively working, keeping the HVAC on recirculate, and saving floors for last.

People underestimate how long particles keep resettling. You will clean a surface, feel finished, and find a fine film again the next day. That is normal; ultrafine particles take time to fall out of the air and out of soft furnishings. Keep running air cleaners and changing filters for days to a couple of weeks, and judge success by whether surfaces stay clean between passes rather than by a single deep clean.

Finally, respect the filter budget. MERV-13 and HEPA filters load up fast in a smoke event, and a clogged filter both restricts airflow and stops capturing well. Buy filters in advance and change them on a short cycle. The filters are cheap compared to breathing the particles they are supposed to be catching, and frequent changes are exactly what the EPA guidance emphasizes for smoke recovery.
