Someone also says to just cut the pins then desolder. Or use a desoldering vacuum tool (maybe both?).

 He has some tips about equipment to use. Desoldering gun, some kind of hotplate (you can use any hotplate), uses a thermocouple to check board temperature (good idea), what soldering wick, and general procedure for heating the board before attempting the actual desoldering.
 Of course usb c ends up being a job for hot air.

-IPA never works. There are products you can buy. E.g. 3Ms novec stuff (which is being phased out but they will likely have a replacement product).What to use will depend upon what solder you use. I would assume that trying to sell universal 'flux remover' is like trying to sell universal 'petroleum remover' in which case, there will be all kinds of traps and variations depending on what actual flux you are using. Make sure whatever you buy doesn't give you a headache (some of the cheap MG stuff did that to me). Look at the MSDS.

 All the categories of flux, and whatnot. It's a lot of abstraction, and it can get in the way. You may be better off just reading the MSDS for a couple dozen fluxes.
