I've done it carefully a few times using the sim card slot tool that comes with the phone. When it gets crusted in there not sure compressed air will do it.

Just use a toothpick

even paperclips are way too large for usb-c slots; toothpicks are even bigger than that, even if you consider their conical shaped tips, so there's absolutely no chance a toothpick will work. The only thing that worked for me was a bent staple.
