This sounds like an opinion written by a "clean hands" computer scientist. Electronic engineers have it easy with their soldering - mechanical engineers deal with much more stubborn oils, greases, metal swarf...

Isopropyl alcohol removes all the soldering residue. Personally, all it took is decent equipment and some practice to make soldering enjoyable. It can be frustrating at times, but usually the problem is (lack of) heat, flux or patience.
