Whether you are changing inks or clearing dried ink after storage, a careful fountain pen cleaning prevents clogs and staining while extending the life of the pen.

In the sections below, you will learn the pen features that matter for maintenance, the components to handle, and how to follow the steps with clean water, gentle flushing, and safe drying. With a converter or cartridge, a paper towel, and cold or room temperature water, you can clean a fountain pen efficiently and confidently, ensuring smooth, consistent writing every time.

Understanding Your Pilot Metropolitan Fountain Pen

The Pilot Metropolitan is a well-balanced fountain pen designed for dependable daily use, and understanding its filling system is the first key to proper maintenance. Most users employ the included converter or barrel assembly—often a Con-40—or an ink cartridge for convenient refills. The nib and feed regulate ink flow from the ink bottle or cartridge through the nib section to the paper.

When you clean a fountain pen like the Metropolitan, you will unscrew the body, hold the grip sections securely, and either squeeze the converter or flush with clean water to remove old ink. Do not pull the nib and feed on a Metropolitan; clean them in place. Knowing how the piston action of converters works, how to use a bulb syringe, and how to clean the nib and bottom of the feed will make the cleaning process efficient and safe.

Components of a Fountain Pen

A fountain pen consists of several interdependent parts: the nib, the nib and feed, the nib section, the grip sections, the converter or barrel, and the cap and body. The nib, including the top of the nib and its slit, delivers ink; the feed channels liquid from the cartridge or converter. The filling system may be a squeeze converter, a piston-style converter, or a disposable ink cartridge, each influencing how you flush.

For a Pilot Metropolitan, using converters such as the Con-40 allows easy refill from an ink bottle and straightforward fountain pen cleaning with running water. Accessories like a bulb syringe or syringe help to flush water until it runs clear. Use a paper towel to wick moisture from the nib and feed after rinsing.

Why Maintenance is Important

Regular cleaning prevents clogs, protects the nib, and stabilizes ink flow, especially when changing inks or if the pen is using pigmented or saturated formulations. Without routine maintenance, dried ink accumulates in the bottom of the feed and nib section, causing hard starts and skipping. A simple cleaning process—flush with tap water or distilled water, use a bulb syringe for stubborn residue, and carefully clean the nib—keeps performance consistent.

Proper care also safeguards the converter seals and piston action, preventing leaks and improving refill reliability. Keeping clean fountain pens also minimizes staining and extends the life of pen and pencil collections. Follow the steps with cold or room temperature water and, if needed, a mild cleaning solution recommended by sources like JetPens to ensure long-term reliability.

Common Issues with Fountain Pens

Common issues include slow or inconsistent ink flow, hard starts, skipping, and a fountain pen that doesn’t write after sitting—nearly always caused by old ink and dried ink in the feed. Residue from certain inks can cling to the nib and feed, especially if the pen is stored with the nib pointing up for long periods.

Air leaks in the converter, a loose cartridge, or debris in the filling system can also interrupt flow. Overly warm water or harsh chemicals may damage seals, while aggressive attempts to pull the nib and feed can misalign parts. The remedy is a careful flush with clean water until it runs clear, then blot dry.

Gathering Materials for Cleaning

Before you clean a fountain pen like the Pilot Metropolitan, gather a simple kit to support a safe, step-by-step cleaning process. Use clean water—tap water is usually fine, while distilled water helps if mineral content is high—and a bulb syringe or syringe to flush the nib and feed.

Keep a paper towel or cloth ready to wick moisture from the nib and feed. Prepare your converter or barrel (including converters like the Con-40), and an empty ink cartridge if you prefer cartridge-based flushing. Have a small container for changing water, a mild cleaning solution recommended by sources such as JetPens, and an ink bottle for refilling after changing inks.

Essential Cleaning Supplies

Gather the Pilot Metropolitan pen, its converter or an ink cartridge, a bulb syringe, and clean water for repeated flush cycles. The syringe or bulb syringe speeds cleaning by pushing water through the nib section until it runs clear. A paper towel is indispensable for blotting the nib and checking for old or dried ink residue.

Include distilled water for a final rinse, especially when using heavily saturated inks. A mild cleaning solution can help when the pen doesn’t recover flow after a standard flush. Keep a small tray to contain parts, and a squeeze converter if your filling system supports it.

Use gentle tools only—avoid anything that can scratch the nib or stress grip sections.

Choosing the Right Ink for Your Pen

Choose dye-based inks for easier flushing and reliable flow in a pen using a converter or cartridge.

For the Pilot Metropolitan, dye-based inks are generally easier to flush with tap water or distilled water, minimizing dried ink in the nib and feed. If you frequently change inks, avoid heavily pigmented or shimmering formulations unless you follow the steps for more frequent cleaning of your fountain.

Match the ink to your filling system: using converters like the Con-40 allows you to refill cleanly from an ink bottle and to flush thoroughly between colors. Test the flow on a paper towel after a refill to confirm clarity. Reputable brands provide reliable behavior and reduce the need to pull the nib and feed, protecting the nib section over time.

Preparing Your Workspace

Set up a stable, well-lit area near a sink with running water so you can flush efficiently and safely handle the fountain pen. Lay down a folded cloth or paper towel to protect surfaces and to catch drips from the nib and feed. Keep small containers for cold or room temperature water rinses and for any diluted cleaning solution.

Arrange tools so you can hold the grip sections securely while you unscrew the body and manage the converter or barrel without dropping parts. Have a bulb syringe within reach to use a bulb syringe between cycles, and set aside a clean tray for the nib section and cartridges.

Organized setup prevents dropped parts and speeds a thorough, mess-free flush.

Step-by-Step Process to Clean a Fountain Pen

This step-by-step cleaning process is tailored to the Pilot Metropolitan so you can clean a fountain pen thoroughly without risking damage to the nib and feed. Begin by preparing clean water—tap water is fine for most areas—and set up running water if available. Have a bulb syringe or syringe, a paper towel, and your converter or barrel ready.

The goal is to remove old ink and dried ink from the nib section and the bottom of the feed, then dry safely before refill. Work gently, hold the grip sections securely, and avoid aggressive attempts to pull the nib and feed. Use cold or room-temperature water; avoid hot water, and if residue persists, use a mild cleaning solution recommended by JetPens to restore reliable ink flow.

Removing the Nib and Converter

Unscrew the body of the pen and hold the grip sections firmly to access the filling system. For a Pilot Metropolitan, do not pull the friction-fit nib and feed; they are best left in place to protect the nib. Remove the ink cartridge or detach the converter from the nib section, taking care not to twist the feed.

If your pen is using converters like the Con-40, cycle the piston or squeeze the converter to expel remaining ink into a paper towel. Rinse the converter separately with clean water to clear old ink. Inspect the top of the nib and the bottom of the feed for residue.

Keeping components organized prevents mixing parts with other pens and pencils, ensuring a smooth reassembly and reliable refill from an ink bottle later.

Flushing the Nib with Water

Hold the grip section under running water and begin a gentle flush. For faster fountain pen cleaning, attach a bulb syringe to the back of the nib section and use a bulb syringe to push clean water through the feed channel. Flush with clean water until it runs nearly clear.

If the fountain pen doesn’t recover flow due to stubborn dried ink, soak the nib section briefly in cold or room temperature water, then resume the flush. Avoid hot water, which can harm seals in a pen using a converter. When changing inks, a final rinse with distilled water helps prevent mineral deposits and preserves consistent ink flow across future refills.

Using a Paper Towel to Dry the Nib

After flushing, wipe moisture by blotting—don’t rub—the nib and feed with a paper towel, allowing capillary action to draw water from the slit and the bottom of the feed. Do not rub the top of the nib; instead, blot repeatedly until the paper towel shows minimal moisture or ink. Stand the nib section, pointing down, on a cloth or paper towel for several minutes to let remaining water drain.

Meanwhile, flush the converter again and air-dry it. If needed, a small amount of cleaning solution can be used on a separate towel, followed by a distilled rinse to ensure no residue. Reassemble by attaching the converter, prime with a squeeze or piston action, then refill from an ink bottle and test on paper.

Tips for Maintaining Your Fountain Pen

Maintaining a Pilot Metropolitan or any fountain pen is about consistency and gentle care. Clean regularly, use suitable inks, and avoid pulling the nib/feed on a Metropolitan. Focus on predictable routines: schedule regular fountain pen cleaning, store the pen correctly, and use inks that support stable ink flow. Avoid aggressive actions like trying to pull the nib and feed on a Metropolitan; instead, clean the nib in place and flush with clean water.

When changing inks, follow the steps for a thorough flush using tap water or distilled water and, if needed, a mild cleaning solution recommended by JetPens. Keep a paper towel nearby to blot the top of the nib and the bottom of the feed, and handle all grip sections carefully. With a converter, cartridge, or Con-40, a simple, step-by-step approach preserves performance and prevents dried ink.

Regular Cleaning Schedule

Clean every 4–6 weeks or whenever changing inks.

For everyday writing instruments like the Pilot Metropolitan, clean a fountain pen every 4–6 weeks, or immediately when changing inks to prevent old ink from mixing. If the fountain pen doesn’t start promptly or shows skipping, perform an interim flush. Unscrew the body, remove the ink cartridge or converter, and use a bulb syringe to push clean water through the nib section until it runs clear.

For stubborn residue, soak briefly in cold or room temperature water, then flush again. Finish by wiping the nib with a paper towel. This routine protects the filling system, stabilizes ink flow, and reduces the risk of clogs in the nib and feed.

Storing Your Pen Properly

Proper storage minimizes leaks and dried ink buildup.

When a pen is inked and in daily rotation, store it horizontally or nib pointing up to limit ink pooling in the cap. If you will not use the pen for a week or more, empty, flush, and fully dry before storage.

Dry the top of the nib and the bottom of the feed with a cloth or paper towel, then leave the nib section to air-dry before reassembly. Avoid heat and direct sun, which can pressurize the ink bottle or the pen using a converter.

Secure the cap to prevent evaporation, and keep pens and pencils in a case that protects grip sections and prevents accidental squeezing on the body.

Preventing Ink Clogs

Use easily flushed dye-based inks and perform periodic water flushes. Use dye-based inks known for easy flushing, and avoid frequent switching to heavily saturated formulations unless you increase your cleaning frequency. When refilling from an ink bottle with a Con-40 or other converter, cycle the piston or squeeze the converter to expel bubbles and ensure a steady ink flow.

If residue forms, use a syringe or bulb syringe to gently flush the nib section, never trying to pull the nib and feed on the Metropolitan. For hard water areas, finish with distilled water to reduce deposits. Always blot the nib with a paper towel after rinsing, and periodically inspect pen features like seals in the converter or barrel. These simple steps keep clean fountain pens writing smoothly.
