I have been fortunate enough to get a "Platignum Italic Set" rather cheap from local used goods store. The unfortunate part is that the pen was stored inked.
I have been soaking it and the dirty nibs in water [with soap], but there is still dried ink in the filler (sac?). It is not just that it is stained, there are opaque spots where I believe there to be dried ink while the rest is fairly clear. It is only been soaking a day, but I have noticed that the metal is wanting to rust.
What is my best course of action?
Is it just a matter of filling it and having it soak not immersed, or is there something else I should be trying at this point?
