How to Care for Your Fountain Pen Nib

A well-maintained fountain pen nib will last decades. A neglected one can skip, scratch, hard-start, or stop writing entirely. The good news: nib care is simple once you understand what's happening inside the pen.

Why Nibs Need Maintenance

Ink is the culprit. Most fountain pen inks are water-based and dry when exposed to air. Inside the pen, dried ink residue builds up in the feed channels and nib slit over time, restricting flow. Pigment inks, iron gall inks, and shimmer inks accelerate this. Even well-behaved dye-based inks will eventually leave deposits if the pen sits unused for weeks.

Regular cleaning prevents buildup before it becomes a problem.

How Often Should You Clean Your Pen?

• Every ink change: Always flush before switching inks. Mixing inks can cause chemical reactions, unexpected color shifts, or sediment that clogs the feed.
• Every 4–8 weeks: Even on the same ink, a monthly flush keeps the feed channels clear.
• Before long-term storage: If you're putting a pen away for more than two weeks, clean it first. Dried ink in a stored pen is far harder to remove than fresh residue.
• When performance drops: Skipping, hard starts, or reduced flow are all signs the pen needs a flush.

The Basic Flush, Step by Step

For most pens, a simple water flush is all you need.

1. Empty the ink. Expel as much as possible either back into the bottle if not completely empty or into the sink.
2. Fill with room-temperature water. Draw clean water into the pen using the same filling mechanism you use for ink. Avoid hot water — it can warp plastic components or loosen adhesives in vintage pens.
3. Expel and repeat. Flush the water through the nib and feed until it runs clear, usually 3–6 cycles.
4. Final flush. Draw in one last fill of clean water, let it sit for a few minutes, then expel.
5. Dry the nib. Gently blot the nib and feed on a lint-free cloth. 
6. Air dry. Leave the pen nib-down on a folded cloth for several hours before refilling. Residual water dilutes your next fill if you rush this step.

Deep Cleaning: When a Basic Flush Isn't Enough

If flushing with water doesn't restore full flow, try these escalating steps. (Please note: that some materials can be damaged when soaked and some pens are not meant to be disassembled.)

1. Soak the nib section. If the pen allows disassembly, remove the nib and feed from the barrel and soak them in room-temperature water for 12–24 hours. This softens dried deposits a flush can't dislodge.
2. Use a pen flush solution. Commercial pen flush — or a diluted solution of dish soap and water — is more effective than plain water on stubborn pigment or iron gall residue. Flush thoroughly with clean water afterward.
3. Ultrasonic cleaner. For serious blockages, an ultrasonic jewelry cleaner filled with water can clear even heavily clogged feeds. Use sparingly, and note that it isn't suitable for all pen materials.

Never use alcohol, acetone, or bleach on fountain pen components. These solvents damage rubber, plastic, and resin.

Troubleshooting Common Problems

Hard starts (won't write on the first stroke)

Caused by ink drying at the nib tip between sessions. Check that the cap seals properly, try a wetter ink, and clean the pen and inspect the cap seal for damage.

Skipping (intermittent flow)

Usually a flow issue. Check that the tines are aligned — look straight down the nib and they should meet evenly. A partial blockage in the feed can also cause skipping, so flush the pen and test again.

Ink flow too wet or too dry

Flow is controlled by the exchange of ink and air. The feed and the gap between the tines play important roles. A wider gap can give more ink, a narrower one less. Adjusting that gap is advanced work, so start by trying a different ink — wetness varies between inks more than people expect, and the fix is often that simple. If this does not solve the problem, your pen may require professional adjustment from the manufacturer or a nibmeister.

Storage Best Practices

• Cap your pen when it's not in use, even for short breaks. Most caps seal within seconds.
• Store daily-use pens horizontally or nib-up. Nib-down storage lets ink pool at the tip and dry faster.
• Store pens cleaned and empty for the long term. An inked pen left for months becomes a cleaning challenge.
• Avoid temperature extremes. Heat expands ink and can cause leaks; cold thickens it and affects flow.

The Payoff

A fountain pen that's cleaned regularly and stored properly writes better, lasts longer, and holds its value — and most of the upkeep is a few minutes with clean water. Browse our full range of fountain pens, inks, and notebooks for pens worth looking after and the ink and paper to fill them.
