Bushings are made of brass or bronze, yellow/brown gold in colour, yes?
Pins are made of grey steel, agreed?
Steel is harder than either brass or bronze, is it not?
So can someone please explain why, when I clean the oil from a pin that's had a busy day or is being run-in, the oil I remove is coloured grey?
