How do you keep the ink from damaging your Koi Nor Rapidograph Pens? I want to make sure they last a long time.
What is the best way to clean them? Do I have to buy special chemicals or equipment? Any advice or instructions would be appreciated. Thank you.





Hi, KoiNor actually makes an ink solvent that works great. It doesn’t smell weird and isn’t harsh on skin. A little bit lasts a long time. Just check with your art store or go to http://www.dickblick.com/itemgroups-p/pencleaners/ and order some. Well worth it.
hi Martha, you might just try soaking the pens in diluted dish washing liquid for a while, worked for me when i was using Koi Nor. It may take a couple of days, but so what. have a good day jb
To add to the excellent advice from “Mark B,” learn how to completely disassemble the Rapidograph. You can break it down right to the fine wire that “wicks” ink into the nib. You have to be EXTREMELY careful with thes small parts, but it’s the only way to thoroughly clean the pen.
Old, dried out ink can clog it up quickly.
