How To Remove The Solder Tin Residue On Double Layered PCB


Happened  to change the header pin of my arduino pro mini  from male to female.
 
Removing the female header is ridiculously tricky and there’s tin residue. Tin sucker (don’t know the proper name) couldn’t remove faster than the time to tin get hard, so theres tin in the hole, here and there... 

Here my pro mini after female header's removed




There's tin leftover so it impossible to install new header there.

To completely remove the residue. Add the small amount of tin to the hole so it easier for the solder to melt the tin on the hole and while it's melting, suck it with sucker from behind it. The tin’s completely removed, :)
