I have a Montblanc Rollerball that I want to refill with my own ink (for more color variety, and to use other inks besides Montblanc's inks, as well as use up my stock of ink.. I have too much).
I looked online and saw tutorials on how to do so. Pop the tail cap off the Refill, pour ink in, pop cap back on. Easy right?
However, my issue pertains to cleaning. Because I would like to change the ink color (originally black). I ran water through the cartridge and after a while it ran clear. But I left it for an hour or so to dry, came back, and flicked it, and got lots of ink coming out again. I figured since the cartridge was old it had some dried up. So I soaked it in water for 3 days. Each day I changed the water and flicked water out of the cartridge. There is always some residual black ink leftover. I noticed that the inside has a piece of felt. Although I don't have tweezers so I couldn't pull it out, I was wondering if the best way was to pull this felt out and clean it out before cleaning the metal cartridge or if there was a more efficient way of doing this. Or should I just not bother with changing ink colors??
Thanks all in advance!
