Owning a fountain pen isn’t just about having something fancy to write with—it’s about enjoying the experience. These pens are designed to last a lifetime, but only if you take care of them. Whether you’ve got a budget-friendly Pilot Metropolitan or a premium Montblanc, regular maintenance makes a huge difference in how your pen writes and feels.
Ink is liquid pigment, and when left sitting for weeks, it can dry inside the feed or nib, blocking the flow. A dried nib can lead to hard starts or even a complete ink clog. A quick rinse every couple of weeks can prevent all that.
Good maintenance also prevents metal corrosion. Some inks are slightly acidic, which can slowly eat away at the metal parts inside your pen if left for too long. Cleaning removes that residue before it becomes a problem. Think of it like changing the oil in a car—routine care keeps things running smoothly.
When you keep your fountain pen clean, filled properly, and stored right, it rewards you with that perfect ink flow every single time you write.
You can always tell when a pen hasn’t been cleaned in a while. The first thing you’ll notice is that it doesn’t start writing right away—this is called a hard start. Sometimes the ink just refuses to come out at all, which usually means there’s dried ink inside the feed.
Another big issue is corrosion. Fountain pen inks are water-based but can contain dyes and additives that aren’t friendly to metal over time. If you don’t rinse your pen regularly, the leftover ink can cause the nib and feed to rust or corrode.
Then there’s leaking. If your pen suddenly starts leaving ink blots or stains on your fingers, chances are something’s off inside—either a clogged feed, a damaged seal, or just too much ink buildup.
These problems are super easy to prevent with regular care. Just give your pen a quick flush once or twice a month, depending on how much you write. If you use heavily pigmented or shimmer inks, clean even more often. It’s a small step that saves you from frustration (and a lot of paper towels).

Before you dive into cleaning or refilling your pen, it helps to have a few reliable tools ready. You don’t need anything fancy — just a small cleaning setup that makes the process easier and safer for your pen.
Start with a bulb syringe, which is one of the best tools for flushing out ink quickly. It attaches perfectly to most cartridge-style pens and helps push water through the feed to clear out leftover ink. You’ll also need distilled water — it’s better than tap water because it doesn’t leave behind minerals that could clog the pen over time.
For more stubborn buildup, a pen flush (you can buy pre-made or mix your own with a mild ammonia solution) works wonders. Keep a small cup or container handy for soaking nibs and feeds, and a microfiber cloth for drying. Avoid tissues or paper towels — they can leave fibers or scratch the finish.
It’s also useful to have a soft toothbrush or rubber bulb blower for detailed cleaning around the nib and grip section. Tweezers or cotton swabs help you reach tight areas inside converters or feeds.
When you’re done, a clean towel or drying rack gives your pen parts a safe place to air dry before reassembling. These simple tools make pen care much faster, cleaner, and less stressful — especially if you plan to maintain more than one pen.
Cleaning your pen sounds intimidating at first, but once you’ve done it once or twice, it becomes second nature. The process depends on how often you use your pen, but here’s a general rule: if you write daily, clean it every two to three weeks. If you use it occasionally, once a month is fine.
Start by disassembling the pen—remove the nib section, converter, or cartridge. Fill your bulb syringe with distilled water and gently flush it through the nib until the water runs clear. You’ll notice old ink coming out in swirls, especially if you’re switching colors.
Once it’s clean, dry everything with a microfiber cloth. Let it air dry completely before refilling—especially if you’re about to use a new ink color.
If your pen hasn’t been used in a while and the ink’s dried inside, soak the nib and feed in pen flush or distilled water for 20–30 minutes. Then rinse again and let it dry overnight. It’ll write like new the next morning.
Refilling might seem simple, but doing it right helps prevent leaks and air bubbles. There are two main systems: cartridge and converter.
Cartridges are the plug-and-play option—just pop one in and go. They’re great for travel but limit your ink choices. Converters, on the other hand, let you use bottled inks, which means you can explore tons of colors and properties.
To refill with a converter:
Dip the nib into the ink bottle until it’s fully submerged.
Twist or press the converter to draw ink up.
Remove the pen and wipe off excess ink with tissue or cloth.
Let a drop or two fall back into the bottle to prevent overfilling.
Test it on paper before reassembling the pen.
If your pen skips after refilling, you might have trapped air. A quick shake (carefully, over a sink) usually fixes it. Refilling is quick once you get used to it—and way more satisfying than using a disposable pen.
When it comes to storing your fountain pens, it really depends on whether you’re using them daily or keeping them away for a while.
If you write every day, keep your pen horizontal or slightly nib-up to prevent ink pooling inside the nib. Always cap your pen tightly after use to avoid drying. Avoid leaving it near windows or heat sources—the ink can evaporate faster or even leak.
For long-term storage, clean the pen thoroughly first. Never store a pen with ink inside—it can dry out and clog the feed completely. Once it’s clean and dry, put it inside a soft case or wrap to protect the finish. Keep it in a cool, dry place away from direct sunlight.
Some collectors also use humidity packs to maintain the ideal environment for their pens, especially in tropical or humid climates.
The key takeaway: a clean, dry pen stored properly will always be ready to write when inspiration strikes—no scratching, no skipping, just smooth ink flow every time.

Even with great care, fountain pens sometimes misbehave. A few quick fixes usually solve most issues.
If your pen dries out, try soaking just the nib section in lukewarm water for a few hours. This softens any dried ink inside. After soaking, flush with clean water, dry it well, and refill with fresh ink.
If you notice mold inside your converter or feed, it’s usually a sign that ink sat too long. Clean the entire section with pen flush, rinse thoroughly, and let it dry completely before using it again.
For ink skipping, check the nib alignment. Sometimes, the tines (the two prongs at the tip) are slightly off. You can inspect them under light—if they look uneven, that’s the culprit.
And finally, if your pen leaks or blots ink, make sure the converter or cartridge is seated firmly. A loose fit often causes that problem. Most issues are easy to fix with a bit of patience and regular maintenance.
Once you’ve got the hang of cleaning and refilling, there are a few extra habits that can help your pen last decades.
Clean it at least once a month—even if you don’t use it much. Inks can dry faster than you think. Avoid using soap or detergent; use pen flush instead, since it’s designed specifically for fountain pens.
Stick to high-quality inks from reputable brands. Cheap inks might look tempting but often have poor flow or particles that clog the feed.
Handle your pen gently—don’t over-tighten the barrel or force the nib into the converter. And never lend your fountain pen unless you really trust the person; everyone writes with different pressure, and a heavy hand can misalign the nib.
Lastly, write with it regularly! Fountain pens actually perform better when used often. The ink stays fresh, and the feed remains hydrated. With these small habits, your pen will easily last a lifetime—and maybe even become a family heirloom.
Taking care of your fountain pen isn’t a chore—it’s part of the joy of owning one. The cleaning, refilling, and storing process connects you to your pen in a hands-on way.
A few minutes of care every month is all it takes to keep your pen running smoothly for years, even decades. It’s a simple habit that makes every writing session a little more satisfying. Whether you’re journaling, sketching, or writing letters, a well-maintained fountain pen makes the experience feel timeless.
