Thanks for the response.
I think my question was probably a little too specific. For anyone else that may be wondering, FrogLube Solvent and some cotton patches did a great job of removing the packing oil.
As for FrogLube itself, I'm not sure that it is working so well with the glossy finish, but we'll see. I don't trust it as a lubricant on the rails, but TW25B and FrogLube get along fine.
