TLDR: My F&C Model 40 Pocket (being used as an eye-dropped) is stained. The stains are on the threads connecting the barrel and the section, and there is also a portion of ink stuck within the feed. I have tried soaking the section/feed unit several times, and the returns have been increasingly diminishing. Please help!
I am a novice fountain pen user. My introduction to fountain pens came when I discovered an old Sheaffer in my mother's closet that had formerly belonged to my grandfather. I spent weeks cleaning and restoring it, by which I mean I soaked the pen in water and blew threw the feed every night for about three weeks until it finally started functioning again.
After this process, I decided I had invested enough time into fountain pens that I should buy another one. I selected the Franklin & Christoph Model 40 Pocket because it is beautiful and entirely different from the Sheaffer I already had. I immediately converted the pen into an eye-dropper and have had a lovely experience with it ever since – that is until the first time it ran out of ink.
I don't use my fountain pen often enough. It probably took me about 2 months to go through the first batch of ink I loaded into it (sailor jentile blue). By the time I was done, the ink had thoroughly penetrated the feed portion of the section (which I believe is inaccessible using a q-tip) and left noticeable staining on the threads.
The technique I used on my grandfathers old pen – soaking it and passing air through the feed – has been ineffective. I have been at this technique for a couple weeks now and am ready to try a new one. Is there a solution I could use in place of water? How might I remove these unwanted leftovers?
Thanks for your help in advance,
