Helen,

    Contrary to some of the pre soldering cleaning I have seen posted my
    basic rules are : 

    1. If oxidizied black then emery
    2. If a water based flux doesn't wet the metal then lightly anneal
    and pickle or wash with soap, water and ammonia. 

    Soldering temperatures do tend to burn off finger prints and minor
    oils; flux dissolves nasty minor oxide coatings. No need to remove
    all of the germs and bacteria, just get everything hot enough quickly
    enough and relax. Soldering is not rocket science, more a case of
    using the right size hammer.
