J. Herbin fountain pen cleaning solution supplied as a tin of 6 cartridges. Use cleaning cartridges the same way as ink cartridges. Rinse the pen under cold water to flush most of the ink out. Push the cartridge into the pen as normal and squeeze the cartridge to push the liquid through. Empty the entire cartridge at once and let it sit in the pen for a little bit. Unplug the empty cartridge and rinse the pen. (The same procedure can be used for J. Herbin rollerball pens, but let them soak longer.) Shake the excess liquid out and let dry before you ink them up. As an alternative, you can also squeeze the contents of a cartridge into a small container and then fully immerse the nib in the liquid for 5 minutes.
