As for the black on the q-tip...I bet that is just a result of the fact you've got ebony scales, no? I don't have that razor, so I don't know how it is sealed, but it might be just a bit of ebony stuff.
And a word on the alcohol as part of the cleanup: careful if scales are sealed with shellac, alcohol is a shellac solvent...moreso with denatured stuff, but I think even isopropyl can get you in trouble.
Me to wife (truth!): "Does she really need all these Barbie dolls? You only need two to have a conversation. Why so many?"
Wife, not skipping a beat: "It's kinda like your straight razors..."
