To be honest I didn't do much apart from desolder the old ones and put brand new ones in, I can see that I should have cleaned the areas now but there wasn't any visable leakage when I took the old ones out. If you think this could be it then I have no issues desoldering the caps and giving the board a clean. Also try to ignore the strange angles of some of these caps I just thought they would be easier to solder like that.
