No, annodized aluminum is very resistant to corrosion. Guitar strings are made out of steel, which rusts readily and plating doesn't adhere as well to flexible materials like wires.

You use an acid flux to remove the oxidation on aluminum. Guess what your sweat will do if it is acidic enough? Hobo soldering tip 101 - no flux, use your sweat if you can get away with sodium in your solder and your solder has no flux.
