A well-maintained fountain pen will write better than a poorly maintained expensive one. The principles aren't complicated — they're consistent — and the difference between a pen cared for properly and one left to chance is the difference between a reliable daily companion and an object that occasionally disappoints. This guide covers every aspect of fountain pen maintenance.
The maintenance schedule
The most important maintenance habit is consistent cleaning at the right intervals. Different inks have different requirements:
Standard dye inks (Pilot Iroshizuku, Diamine, Waterman): Clean the pen thoroughly every four to eight weeks, or when changing ink colour. Between changes using the same ink, a brief rinse every four weeks is sufficient.
Iron gall inks (Diamine Registrar's, Platinum Classic range): Clean every two to four weeks. Never leave iron gall ink in a pen for extended periods without writing — the iron compounds interact with pen components over time. Flush thoroughly before storing.
Shimmer inks: Clean every one to two weeks. The glitter particles accumulate in the feed fins and restrict flow if left too long. Pens with removable nib and feed (TWSBI, LAMY Safari) are much easier to clean of shimmer than those with fixed nib units.
Pigment inks (Platinum Carbon Black, Sailor Pigment series): Clean every one to two weeks. Pigment inks dry into the feed if left unused and can be very difficult to clear once dry. Never leave a pigment ink pen sitting for more than a week without writing or cleaning.
Correct cleaning technique
See our complete cleaning guide for step-by-step instructions. The key points: use room-temperature water only (never hot), flush until the water runs clear, and allow the pen to dry completely before refilling — the feed retains water longer than it appears, and refilling too soon dilutes the new ink.
Storage
Short-term (daily use): Store pens horizontally or nib-up. Nib-down encourages ink to pool forward and can cause leaking. Most pen cases and stands store pens horizontally, which is the safest orientation for pens in regular use.
Medium-term (days to weeks): Keep the pen capped. The cap protects the nib from drying. Even a few hours uncapped can create hard starts with some inks; a week uncapped may require cleaning before the pen will write reliably again.
Long-term (weeks to months): Clean the pen thoroughly, allow to dry completely, and store empty. A clean, dry pen stored for months will return to service quickly; an ink-filled pen stored for months may have dried ink problems requiring extended soaking to resolve.
Temperature: Avoid very hot environments (cars in summer, direct sun). Heat causes ink to expand, which can force ink past the nib and create leaks. The materials in some pen bodies — particularly heat-sensitive resins — can warp at high temperatures.
Nib care
The nib should never contact hard surfaces. Place the pen down with the cap on, or on a pen rest with the nib section protected. A nib that's dropped point-first on a hard floor is almost certainly damaged beyond easy repair.
Check nib alignment periodically — hold the pen to the light and look straight down the nib. The two tines should be even in height and the gap between them should be consistent. Misalignment causes scratchiness and ink flow problems. Minor misalignment can often be gently corrected; significant misalignment is best addressed by a specialist.
Never attempt to "flex" a non-flex nib. Pressing hard enough to spread the tines beyond their designed range permanently damages them. Fountain pen nibs are not dip pen nibs — they're not designed for pressure.
Ink management
Store ink bottles away from direct sunlight. UV light degrades some dye inks over time, shifting their colour and reducing vibrancy. A cupboard or drawer is better than a desk top display in direct light. Keep bottles tightly capped between uses — air exposure gradually evaporates water and concentrates the ink.
Don't mix inks from different bottles or brands in the same pen without cleaning thoroughly between. Some ink combinations react and produce sediment, gels, or colour changes — not usually dangerous to the pen but potentially damaging to the feed and difficult to clean. The cleaning process also removes any chance of unexpected chemical interaction.
Travelling with fountain pens
Air travel creates cabin pressure changes that can cause ink migration in partially-filled pens. Either fill the pen completely (leaving as little air as possible in the reservoir) or empty and clean it before flying. Carry pens in a protective case — horizontal — in cabin luggage rather than checked luggage. Checked luggage experiences greater temperature and pressure extremes than the cabin.
The reward of proper maintenance
A fountain pen that's cleaned regularly, stored correctly, and used with appropriate inks will write reliably for decades. Many of the pens most loved in the fountain pen community are not new — they're thirty or forty year old objects maintained with care. The pen that writes beautifully every time you pick it up is the pen that's been looked after every time it's been put down.
