I came across this problem when fixing my DHA pedal - my solution was to have some solid core wire (about the same diameter as a 24 or 26 AWG multi-strand) and to strip abut 30 cm of the insulation off it. Next I heat the solder pad using a temperature controlled iron and feed the solid core through the hole in the PCB - as it travels through the hole it will pick up any errant nasties or stray wires that remain. Once the solid wire is through you should have a nice clean hole, then I used my wire cutters to chop the 'spent wire' off, leaving the rest of the reel ready for the next use. You may have to do this a couple of times, but I find that it works well in tight spaces where you can only realistically desolder the solder side of the board due to the component side being too full. 

 

Hope this helps.

Another effective variation of that is a pcb drill bit. Heat the pad, push the drill through the hole while the solders melted, then spin the drill bereeen fingers as you remove the iron to prevent the solder sticking.
