Needed something to clean all the nibs from my dearly departed brothers line pen, we had one thing in common the love of tech-design he was an engineer whilst I like to draw with inks so similar (grabbing at straws) the nibs had not been used for a long while so much so that the inks had dried to a gunk and as much as I tried I couldn't shift it all, on review I found this was the most often used so gave it a try, it removed the gunk without any faff. Therefore try it, great quality and inexpensive too.
