I have often seen that we should remove flux from a PCB after soldering but I have not seen any reason given.
It occurred to me that painting the finished DIY board with liquid rosin flux might work well to protect the bare copper from corrosion yet leave it easy to solder/desolder if necessary.
Is this a bad idea?
