Tarn-X works great for removing oxididation from chip pins without a lot
of work or risk in harming the chips.
Soak the chips in a shot glass until all black oxidation is gone; then,
remove the chips and put them in another shot glass with alcohol to rinse. I
use a third shot glass with alchol again to be sure and, then, take out the
chips and let dry.
