lol please read more regarding alcohol, 99 not always good, better 70 for microbes. And spores will come back. Go sand affected areas while outdoor and wear mask, alcohol and vinegar wipe wipe, left sunlight, coat with paint/coating

So much trouble

I check again affected area seems like gone.

I suspect ventilation is the key. More ventilation less moisture.

go check where your water leakage came from,.. turn off all your pipe in your house, but outside main remain open,.. then go see the water meter still moving or not,.. if still moving,.. u got internal pipe leaking,..

no point treat the symptom without treating the real cause of the problem,.. water leakage,..

Ok. Sounds good idea. But I think the leak come from roof but it's already fixed

If got aircond use dry mode once every 2 weeks for 8 hours. Wick all the moisture away
