Is there a large #FountainPens community on the fedi?
Anyhow, I have a dedicated blue #Lamy Sarafi that I used to use for my #BaystateBlue ink, because it's notorious for permanently staining everything it comes into contact with. A while ago, I accidentally let ink dry out in this pen, and I haven't been able to get the feed flowing properly since. I've cleaned the pen several times and left everything soaking in water for several hours on a few occasions. I've also tried changing the nib. Eventually, I just emptied it, cleaned it out, and left it sitting on a shelf for a while.
I recently pulled it out again, cleaned it once more, and inked it up. Same problem. I'm going to leave it sit inked for a bit to see if maybe capillary action will eventually set in, but if this doesn't resolve the issue is there anything else I can try? I can always replace the pen, but I'd rather not if it can be avoided.
@me vinegar is pretty safe in general and you can always dilute it. I think the safari has a plastic feed, too.
if it were me I would use a little dishsoap and an old toothbrush first and try to get into the feed's nooks and crannies. if the suds turn blue, it's working
