I've recently purchased a Montblanc Blue Hour LeGrande fountain pen with a medium nib and I am really enjoying it. I have finally found my paring for Nib and Paper, using Thome River paper. I was anxious to test different inks in the pen and I went on an ink purchasing frenzy. I had Pilot Iroshizuku Kon-Peki ink and it is my go-to ink as I truly love the color and how the ink flows. It really is top shelf ink.
In addition to Kon-Peki, I bought some Diamine, Montblanc, Waterman, and Pelikan Edelstein inks. I had no issues flushing out the inks with normal tap water as Montblanc Suggests in the video below. However, the Montblanc Permanent Blue seems to have stained the nib and the feed. Yes the nib is stained and will not wipe off. To me this is most alarming so I've been doing research on cleaning the pens. My normal practices for cleaning the pen seem to be in line with the industry standard.
Minus the nib cleaners I've followed the below video nearly identically (minus dropping 6 drops back into the ink). I have just picked up some nib cleaners from my local boutique today but have yet to clean them. I asked for pen flush but they only had the flush for cartridge/converter pens.
I showed my pen to the Boutique Manager today and she was very surprised. I am concerned how the inside piston will end up looking if the NIB was discolored... She did offer to send the pen out for a full cleaning but I am concerned because I LOVE the blue color of the Permanent Blue... but I know it will just stain again. Now the discoloration/staining is very faint, however, under light it is prominent and can be easily seen. She has a meeting tomorrow and intends to bring this up.
My question is, how is the Goutlet Pen Flush? I know it is probably dish soap and water, but does anyone know how effective this pen flush is? Has anyone had any experience with Goutlet Pen Flush? Has anyone had a similar issue with the Montblanc Permanent Blue ink and was able to clean it without issue?
