Good Flux
I generally just use flux paste when de-soldering, this paste works well and cleans up easily.

Flux for electronics soldering
My flux came inside the container and not stuck to the lid, for what that’s worth! Im using a toothpick to coat my wires with the flux (consistency reminds me of bee’s wax). I have also used my 2nd hands metal base, plopped a chunk of the flux there and used my heat gun to melt to dip wires. As a hobbyist these two cans will last me a while!

This stuff works
This was the first flux I ever bought and it made a world of difference. I tried to make my own liquid flux and a real paste to put in a syringe with 91% and 95% ipa. It didnât work very well at all. I got a tiny amount of liquid flux but a paste is pretty much impossible to make with this drug and ipa. I found it hard to use the proper amount of flux and put it where I want it so Iâm more of a paste in a syringe guy but this stuff is still useful. Itâll last you a long time
