But before that I had to get rid of all the oozed filament, even on the threads at the connections. I found an odd trick. NOTE my filament was PLA. I soaked the metal parts in Acetone. It does not dissolve the PLA but rather breaks it down so that anything left over is like dust which can be wipe off easily after it is left to dry.

Hope this helps,
Cheers.
