I recently received my F-C 02 Intrinsic in smoke and ice with a medium SIG grind, and I'm in love -- the nib, the design, and the finish have all made this easily my favorite pen to date. However, I've encountered an issue that I haven't seen discussed before:
When filling the converter, ink is drawn up between the nib assembly and the section acrylic. This, in itself, is probably to be expected, and the finish definitely makes it more conspicuous than it otherwise would be. However, I did notice, after only my third fill, a slight bit of staining in this area. The culprit was Iroshizuku Shin Kai.
This happened despite cleaning between fills. Now, no matter what I do, I can't seem to get rid of the light purple-blue hue of my virtually brand new section. I've definitely heard some warn against ED'ing these pens with Iroshizuku inks, but just filling the converter? Is the antique glass considerably easier to maintain and clean? I know I could try an ultrasonic cleaner or F-C's recommended ammonia/water solution, but it just seems too soon. Are the ultrasonic cleaners best for this finish? Any smoke and ice owners out there have any input or suggestions on how I might avoid this in the future? Are there certain inks which should be avoided even in converters?
Thanks much in advance, all. I look forward to posting here more often!
