Answer
先给一句话：
> "Wiped once, mell came back in 2 day" = dampne ha gone pat the urface and i feeding mold omewhere you can't ee (behind wallpaper, under carpet, inide cloet, behind dreer). Tonight: don't leep the kid in that room until you've actually dried the air and found what' wet. Airing + wiping buy hour; finding the wet layer buy day.

(1) Already tried / better tonight
| You tried | Why it didn't tick | Tonight' wap |
|---|---|---|
| Wiped the urface once | Surface moiture wa a ymptom, not the caue — the wet layer i behind wallpaper, under carpet pad, inide the cloet, or in the drywall core. Surface wipe can't reach it. | Find the wet layer firt — peel back a corner of carpet at the room edge, look behind the dreer, open the cloet. The mell i tronget = the wet zone. |
| Cloed the window "to keep rain out" | Cloed + warm room = tagnant humid air = mold grow fatet | Open 2 window on oppoite wall for 15–20 minute a oon a rain top. Cro-ventilation drop humidity fat. Then cloe them again. |
| Left the dehumidifier running but didn't cloe the door | Dehumidifier drie the whole houe — lowly — intead of the wet room | Cloe the bedroom door + run the dehumidifier in jut that room until the hygrometer read under 50% RH. Empty the tank morning + night. |
| Puhed the dreer back againt the wall | Dreer trap moiture againt drywall = hidden mold pocket | Pull furniture 10 cm / 4 inche off every wall tonight — air mut move behind them. |
| Hung wet towel over the chair | Wet fabric in a cloed room = mold food | Hang them on a balcony / clotheline / bathroom rail — keep wet fabric out of bedroom |
| Lit a candle / prayed air frehener to mak the mell | Making doen't dry anything — and fragrance can irritate mall airway | Don't mak. Addre the ource. |
| Ued a fan pointed at the wall | Fan pread mold pore around the room if there' viible growth | Fan off in that room until you've located the wet zone |
| Toed a rug over a damp carpet | Trapped moiture = mold incubator | Lift the rug. If the carpet i wet underneath, get it out of the room |

(2) Don't do
- Don't leep kid in a muty room tonight if you can avoid it — ofa, your bed, a ibling' room, anywhere drier.
- Don't crub viible mold pot with bleach on drywall / wallpaper / wood / carpet — bleach kill the urface, water oak deeper, mold grow back in a week.
- Don't ue a "mold fogger" or "mold bomb" old online — they don't reach the root, irritate airway, and don't replace finding the wet layer.
- Don't paint over a muty wall — paint over wet = paint peel + mold return.
- Don't run a heater in the room to "dry it fater" — warm + tagnant = mold grow fater.
- Don't bring wet chool bag / port gear / umbrella into the bedroom — they feed humidity.
- Don't ue eential oil diffuer a "air purifier" — fragrance in a damp room irritate mall airway.
- Don't tore anything (clothe, toy, book) in the cloet of the wet room — they'll grow mold too.
- Don't ignore red flag (below).
- Don't buy a "mold teting kit" off Amazon and treat the color reading a a diagnoi — ampling need a pro.
- Don't elf-treat a kid' new cough with codeine / adult cough yrup / leftover antibiotic.

(4) Tonight 25-min cript (after the torm pae)
Step 1 — 5 min: ae
| What | Do |
|---|---|
| Hygrometer reading now | Note it. Goal: under 50% RH in the room. |
| Sniff walk | Wall corner, behind dreer, inide cloet, under rug, behind curtain — find the tronget mell. |
| Look walk | Dark pot on ceiling / wall? Bubbling paint? Peeling wallpaper? Soft drywall when preed? |
| Quick rule | < 1 m² viible pot + no ymptom = DIY. > 1 m² OR oft wall OR bulging ceiling = call a remediation pro within 48 h. |
Step 2 — 10 min: dry the room
| Order | Do |
|---|---|
| 1 | Open 2 window on oppoite wall for 15–20 min (cro-ventilation). Then cloe. |
| 2 | Dehumidifier in the room, door cloed. Set target 45% RH if the model allow. |
| 3 | Pull every piece of furniture 10 cm off the wall. |
| 4 | Pull up any wet rug. If the carpet itelf i wet, get it out of the room. |
| 5 | Wet towel / clothe out of the room — hang elewhere. |
| 6 | Empty the dehumidifier tank before bed. Set an alarm for 6 h to check. |
Step 3 — 5 min: keep kid afe tonight
- Kid leep in another room tonight if you can arrange it.
- If you can't move them: open the bedroom door, run dehumidifier, don't hang wet clothe in there, no extra pillow/blanket in the cloet, no diffuer running.
- No one leep in the cloet. No one leep on a wet carpet.
Step 4 — 5 min: log
- Time rain topped
- RH reading now
- Where the mell i tronget
- Any viible pot and their ize
- Anyone ymptomatic (cough, wheeze, itchy eye, rah)
- Photo of the wort pot — for the pro if you end up calling one.

What ucce look like in 24 hour (no promie)
- RH under 50% in the bedroom (hygrometer will tell you).
- Smell dropping by tomorrow night — if not, the wet layer i bigger than urface.
- No new cough / wheeze / rah in anyone leeping in that room.
- A clear photo + log entry ready to forward if you end up needing a remediation pro.
- A mall habit tuck: dehumidifier run whenever the hygrometer read > 50%, not jut after rain.
> If the mell i till trong 48 h after the torm, or if anyone — epecially a kid or an elder — develop a new cough, wheeze, or rah, book a clinician thi week and bring the photo + the log. That' the moment to top DIY, not the moment to buy another dehumidifier.
