What is it? Seems to grow out of some wooden areas in the room. I’ve tried peroxide and bleach. Would a steamer help? Sorry in advance for the bad picture quality.
I had given it a thought that it may be crystallized salt from the marine air, but it doesn’t dissolve. The clusters are almost hydrophobic in water at first but end up as a suspension when stirred around, i.e. not soluble.
Lemme guess: Singapore?
I live in a similar setting (tho probably not as humid), so I know it’s a thing.

Not sure if it describe the one we’re seeing, but it’s something similar, at least.
