Refer to this video. It seems pretty straight forward.

solder out of cloth....like socks or pants. ( and eyes!! )
-Clean the tip by wiping it quickly on a small pad of wet cotton cloth.
-Place tinned iron to object you want to solder and hold it there until the heat from the iron heats the object. ( A tinned iron will transfer heat whereas
a un-tinned iron won't. ) This should take seconds for a small object.
-apply the solder to the heated object, not the iron.
-the whole process should be done as quickly as possible so as not to allow the soldering iron to oxidize too much between operations.
(you will see what I mean) Clean the tip, again, by wiping it quickly on a small pad of wet cotton cloth and apply a touch more solder to the tip.
-allow to cool, for a moment before moving the solder joint.
-Before you try to do this on something expensive, practice on scraps of wire or an old circuit board from some junked gadget.
The smoke from the rosin is somewhat toxic, with acid and maybe lead etc. I use a small fan to blow the smoke away from me.
