When the Ink Runs Dry: How to Clean a Fountain Pen
When the Ink Runs Dry: How to Clean a Fountain Pen
The last lines in your notebook are blue, but the next cartridge waiting on the desk is a different colour. Before opening it, you pause over the pen in your hand. Is a rinse enough, and which parts belong in the water?
The practical answer to how to clean a fountain pen is to identify its filling system and materials, then follow the manufacturer’s routine. Sailor provides separate cartridge and converter methods using water, with an important exception: transparent or skeleton-coloured sections must not be soaked; its alternative is rinsing only the nib with water. Your specific pen and ink instructions take precedence.
How to clean a fountain pen: check its filling system first.
Before preparing the cleaning water, establish whether your pen uses a cartridge, a converter, or a piston-filling system. That distinction determines which instructions apply. Sailor’s cartridge routine begins by removing the cartridge; its converter routine uses the converter to draw in and expel water before the converter is removed.
These are manufacturer-attributed procedures, not a universal recipe for every fountain pen. Keep your model’s instructions nearby, particularly if you are uncertain about the section’s material or how the filling system operates. A pen’s appearance alone should not be treated as permission to follow every step in a general care guide.
The source for the methods below is Sailor’s fountain pen care guide. Read it alongside the instructions supplied for your own pen. If those instructions differ, use the specific guidance rather than combining procedures from different models.
Materials and method at a glance
Sailor lists a cup of water and a soft cloth or tissue paper as cleaning materials. Its rinsing instructions specify tap water. The distinction between the two routines is not a longer shopping list: it is whether a cartridge is removed at the start or a converter is first used to move water through the pen.
| Point of comparison | Cartridge routine | Converter routine |
|---|---|---|
| Materials | A cup of water; soft cloth or tissue paper. | A cup of water; soft cloth or tissue paper. |
| First stage | Remove cap, barrel, and cartridge. | Draw water in and expel it five to six times using the converter. |
| Section treatment | Soak the gripping section overnight where appropriate. Do not soak transparent or skeleton-coloured sections; rinse only the nib with water instead. | Remove the converter and change the water, then soak the nib section overnight where appropriate. Do not soak transparent or skeleton-coloured sections; rinse only the nib with water instead. |
| Finish | Rinse with tap water and wipe dry. | Rinse with tap water and wipe dry. |
The material exception is part of choosing the method, not an optional caution after the work is finished. Resolve it before starting.
Cartridge cleaning, with material exceptions.
For a cartridge pen, Sailor’s sequence starts with the ordinary components named in its care guide. It does not call for removing a nib or feed. Here, “gripping section” refers to the part identified in the manufacturer’s procedure, not an invitation to take that assembly apart.
- Check the applicable instructions. Confirm that the cartridge routine suits your pen and identify any material-specific restrictions. If you cannot establish the section’s material, seek model-specific guidance before proceeding.
- Remove the cap, barrel, and cartridge. These are the opening actions in Sailor’s cartridge-cleaning instructions. Stay within that stated scope; do not extend the procedure into further dismantling.
- Follow the section treatment only where appropriate. Sailor instructs users to soak the gripping section overnight. Do not soak a transparent or skeleton-coloured section; Sailor’s alternative is rinsing only the nib with water. Your model’s restrictions still take precedence.
- Rinse and wipe dry. Sailor’s routine finishes with rinsing using tap water and wiping dry with the listed soft cloth or tissue paper. Follow any additional finishing instructions supplied for your specific pen.
These steps are attributed to Sailor’s care guide. They should remain a bounded routine: identify the pen, remove the named components, use the appropriate water treatment, and finish as directed. A different material does not justify improvising a different cleaning solution.
Notice that the transparent-section alternative is narrower than the standard section treatment. Sailor says to rinse only the nib with water. Do not reinterpret that wording as permission to immerse the complete section briefly or to leave it in water for a shorter period. The exception changes the treatment, not merely its duration.
Converter cleaning, with material exceptions.
When cleaning a fountain pen converter, the order matters. Sailor first uses the converter to draw water in and expel it, then removes it before the next stage. This is distinct from the cartridge method, where the cartridge is removed at the beginning.
Read the converter instructions for your model before operating it. The general care sequence does not provide authority to force an unfamiliar mechanism or to dismantle the converter itself. If its operation is unclear, pause and consult the pen’s instructions or dealer.
- Prepare the water and wiping material. Sailor lists a cup of water and a soft cloth or tissue paper. Confirm the model’s material restrictions before beginning.
- Draw water in and expel it five to six times. This is the repeated flushing action specified in Sailor’s converter routine. Use the converter according to its own operating instructions.
- Remove the converter and change the water. Sailor places these actions after the repeated draw-and-expel stage. Keep that sequence rather than borrowing the opening step from the cartridge method.
- Apply the appropriate section treatment. Sailor instructs users to soak the nib section overnight where appropriate. Do not soak transparent or skeleton-coloured sections; rinse only the nib with water instead. Follow any more specific restriction for your model.
- Rinse with tap water and wipe dry. These are the finishing actions in Sailor’s guide. Use the listed soft cloth or tissue paper, together with any applicable model-specific instructions.
The phrase “nib section” should not be mistaken for an instruction to detach the nib. Sailor’s supplied routine describes cleaning the section, not extracting its internal components. Keep that boundary intact even if the pen still has a flow problem afterwards; unresolved performance has a separate next step.
When an ink change or storage calls for cleaning.
Sailor recommends regular water cleaning, ideally every two to three months. Its guide specifically highlights poor ink output, switching ink types or colours, and putting a pen away for an extended period. Those occasions provide a practical framework without requiring an invented cleaning schedule.
For the ink change in the opening scene, the useful question is not simply whether the old cartridge is empty. You are changing colour, which is one of Sailor’s stated reasons to clean. Identify the filling system, check the materials, and use the applicable routine before continuing under your pen and ink instructions.
Changing ink type deserves the same attention because Sailor names it explicitly. This guide does not establish which inks can be combined or make compatibility promises. Where the ink manufacturer provides handling or cleaning directions, keep those directions alongside the pen’s own guidance.
A storage example
Suppose you are putting a cartridge pen away while you use another writing tool for an extended period. Rather than treating storage as an unrelated task, use Sailor’s cartridge routine where it applies: check the materials, remove the cap, barrel, and cartridge, and follow the correct section treatment.
If that treatment includes overnight soaking of the gripping section, exclude transparent or skeleton-coloured sections and rinse only the nib with water instead. Finish with the prescribed tap-water rinse and wiping dry, then follow the model’s storage instructions. Sailor’s cited routine does not supply a separate drying timetable, so there is no reason to invent one here.
This example is deliberately ordinary. Cleaning before storage need not become a deeper disassembly project. The aim is to carry out the manufacturer’s relevant care steps while respecting the pen’s materials and the limits of the instructions.
What not to soak or dismantle.
The clearest exception in Sailor’s section-cleaning guidance concerns transparent or skeleton-coloured sections: do not soak them; rinse only the nib with water instead. This restriction belongs beside the procedure every time it is considered, including preparation for an ink change or storage.
Other materials also require care. Sailor warns that alcohol-containing wipes or chemicals can damage resin. It also warns that wooden barrels exposed to water may expand and crack. These cautions are reasons to keep the routine within the named components and materials, not to immerse a pen indiscriminately.
Do not turn a cartridge or converter procedure into whole-pen immersion. Sailor’s piston-filler instructions are different and warn against soaking the entire body. If your pen is a piston filler, consult the relevant section of Sailor’s care instructions and your model’s own instructions rather than adapting the steps above.
Likewise, the supplied cartridge and converter methods do not instruct you to remove nibs or feeds. A maintenance guide should make the stopping point clear: removing a named cartridge or converter is not permission to dismantle the writing assembly. If something resists normal operation, stop rather than forcing it.
The boundaries matter as much as the sequence. Knowing what the guide does not authorise helps keep a routine cleaning task from becoming an unsupported repair attempt.
When cleaning is not enough.
Water cleaning is a manufacturer-recommended response to poor ink output, but it is not a promise that every flow problem will disappear. Sailor’s frequently asked questions directs readers to their dealer if cleaning does not resolve poor ink flow.
That is the appropriate next step after completing the applicable routine. Do not escalate by taking the nib assembly apart or adding an unlisted treatment. Contact the dealer and explain what you observed, which filling system the pen uses, and which cleaning instructions you followed.
Keep the distinction between care and diagnosis clear. The sources support a water-cleaning routine and a referral when it does not resolve the problem; they do not establish the cause of every interruption in writing. Seeking guidance preserves that distinction without asking you to guess at a repair.
A quiet routine for the next page
Fountain pen cleaning starts with identification, follows the appropriate manufacturer sequence, and ends at a clear boundary. Keep your specific pen’s care instructions beside your writing tools so that an ink change or storage decision begins with the right guidance.
For broader choosing advice, see the related first-fountain-pen buyer guide. If you are considering the TUZU ADJUST Fountain Pen Medium Size, consult its own care instructions; its listing does not establish model-specific soaking permission. The maintenance principle remains restrained: follow the applicable instructions, respect material exceptions, and ask your dealer when cleaning is not enough.
