Do you know you can make your own liquid soldering flux? And possibly flux pen refill for cheap? All you need is some solid soldering rosin and 95% ethanol alcohol. Cheap, kind of dirty, but works…
If you really really want, you can solder without flux. But it is a painful experience. Almost all modern solders have flux integrated into its core. And as long as you do not try to solder anything big, it’s enough. Of course, sometimes it is not enough and you have to help yourself with additional flux.
My favorite solution lately is a flux pen. Like Stannol x32-10i
