I've watched a bunch of youtube vids of soldering and de-soldering too. Looks easy enough, but I have had no success thus far.

Strange.
First up you have been able to tin the tip of the iron - to tin the iron you let it heat up and then hold the end of the thin flux cored solder against it, the solder will melt on to the tip giving it a coat of solder. It is this coat of solder that is responsible for transferring the heat from the tip to the object you are trying to solder/desolder.
Another thing, never use separate flux on electronic components unless you have the non corrosive type. Always use flux cored solder and if you are finding it difficult to melt the original solder apply the tinned tip to the solder and then apply the cored solder to it - strange as it may seem adding a little more solder usually does what you want and melts the old solder then you can use a solder sucker - while the iron tip is still heating the solder - and remove all the solder at that joint - repeat as necessary.
Since you have put flux on the board make sure you clean it all off once you removed the switch.
The solder we use is grade K 1.2 mm dia with RS3 flux type, although we may use 0.5 mm dia for some small surface mount components.
Good luck.
