Yes, as I supposed. So let's repurpose this thread to understand what happened.
Looking with a magnifier lens I'm seeing that there are no tiny droplets of water as I supposed (so it's already dry), but a web of linear segments. It could be water that evaporated and left salt crystals. The plot thickens, as I don't think condensation water contain salt. I'll post a macro photo of it later.
