    Utilize Flux and alcohol. Clean with alcohol utilizing a wipe-clean-wipe method. After soldering with Flux, clean off residual Flux with alcohol. Leaving Flux can promote corrosion. My phone keeps autocorrecting Flux to capitalize it, and I don’t care enough to fix it. 🤷‍♂️

    Edit: Do not use clinical isopropyl alcohol solutions (~70% whatever). Those solutions need some water to work as a disinfectant. You want as little water as possible (>99% solution).

    Believe it or not, isopropyl alcohol leaves residue behind. If you’ve ever wiped a shiny metal surface with it, you might see it looks a bit duller. Wiping after using alcohol is attempting to remove the residue to give the cleanest bonding surface possible.
















  • It’s the inability to see the forest for the trees. We were raised in a capitalist economic system, as were all of our past family members. The failings of capitalism appear to be the failings of human nature. In reality, meta analysis of multiple studies on human greed show that people will be inherently more kind to each other than be cruel. Quick search will bring up many articles on these studies. Plus, exchanges in material goods within communities where money hadn’t been invented would show that people didn’t barter, they gave their goods away to their neighbors, and the good deed would be remembered and reciprocated in times of need. You can look up “Gift Economy” in Wikipedia.
