First spread some flux on the wood panel that you will be using for soldering (some small plywood piece should work)
with hot iron melt the flux and dip(or thread through) your bare wire through the flux equally spreading it over the wire surface with the hot iron.
Than(if you're using a RadioShack silver solder) cut approximately 1 ring of solder and melt it inside the spreaded flux and thread through the bare wire equally spreading solder over the bare wire surface.
Define for yourself how often you need to clean soldered ends(and sometimes binding posts as well) simply by checking it's surface once in a while starting from once per week.
