VERDIGRIS IS COPPER CORROSION ( Thanks Susan! )

[gordon stelter]

Yes, stainless might help. It is also useful to soak
parts in lacquer thinner to get out unwanted oils 
( if my SuperClean(TM) method seems too
shocking,though it works superbly with filthy/smelly
stuff. )
     They could be pointed by twirling them at an
angle on a fine sharpening stone, I'd think. Or
silicone carbide sandpaper taped to glass.  
     Peace,
     G
