Probably paint then.

as above. try nitromors, if not that then move on to caustic. you sure its not powdercoat? pix would help....

ED209:
Synstrip if its paint.

Or it might be what they call Hard Anno ... have a couple of goes with Oven pride or get Caustic as Phil said  :daumenhoch:

MartyC:
Sugino CT cranks are 4130 Cro Moly so are not annodised.  Did you mean Sugino GT?

What colour were they before?  Ovenpride can sometimes turn the alloy a blackish colour due to the contaminants on the alloy surface, it should polish off.
