I have put flux on a PCB to solder. Can I leave it overnight? Is that ok? Or how long can flux be on the board?

Water-soluble Flux must be removed from the PCB as quickly as possible after soldering. So you cannot leave it overnight. The manufacturer of your Flux will have their recommendations in the data sheet.

My experience is that Kester Water soluble flux left on the PCB for more than 5 hours leads to the beginning of corrosion.
