Doing full tear downs, Naptha works great, Pros: easy to dab a little on a cloth or paper towel, evaporates at a good rate (not as fast as alcohol, but fast enough to move quickly). Can be purchased at box stores. Cons:leaves a residue, but that is easily wiped away, should wear gloves (nitrile), and ventilate if using more than a few drops at a time. Dirt, grease, other. If that doesn't work, I'll try something else, but works great on metal parts.
