How to Clean a LAMY Fountain Pen: Cartridge, Converter or Piston

Step-by-step instructions

Step 1: Identify the filling system before opening anything

A Safari-style cartridge pen has a removable barrel and an ink cartridge or converter inside. The LAMY 2000 fountain pen instead fills with a built-in piston. Do not try to pull that piston out as though it were a cartridge. Put a cloth on the work surface and keep the drain covered if you work near a sink. Empty loose items from the area so small components cannot disappear among them. Photograph the assembled pen if you are unfamiliar with how its barrel and filling unit fit.

Step 2: Remove the barrel and ink supply on cartridge models

Hold the grip securely and unscrew the barrel without twisting the nib. Pull out the cartridge or removable converter as appropriate. Set a partly used cartridge upright in a stable container while working; its open end can release ink. Rinse the grip with the nib pointing down under a gentle stream of water to remove loose ink. Keep decorative barrel sections out of the soak unless they actually need cleaning. This is an ink-path procedure, not a bath for every finish and accessory.

Step 3: Soak the grip when ordinary rinsing is insufficient

For a cartridge or converter pen, place the grip and removable converter in room-temperature water. Replace the water when it becomes strongly colored. LAMY Australia's care guide uses water remaining clear for an hour as the endpoint for its basic soaking method. That is an observation about the water, not a requirement to leave every pen overnight. Keep the nib protected from the bottom of a crowded bowl. Do not add alcohol, bleach or a homemade chemical flush to this water-only routine.

Step 4: Flush with a converter or a gently fitting bulb

Use one cup for clean water and the second to catch inky water. With a compatible converter installed, immerse the nib, draw water in as if filling with ink, and expel it into the waste cup. Repeat with fresh water until the discharge is clear. A bulb syringe can instead deliver a slow stream through the cartridge connection, but it must fit without stretching or forcing the opening. Do not use an air compressor or pressurized tap attachment. A blockage calls for patience, not higher pressure.

Step 5: Use the piston branch for a LAMY 2000

Leave the built-in filling system assembled. Operate the piston as you would for filling: prepare it by gently turning the rear knob, immerse the nib in clean water, and draw water in. Expel the water into the separate waste cup and repeat until it runs clear. Stop at the normal travel limits rather than tightening the knob harder. Do not apply the removable-grip soaking sequence indiscriminately to an assembled piston pen. If the piston is stuck or unusually resistant, stop and seek the model's service instructions.

Step 6: Drain and dry without bending the nib

Gently blot water around the grip and nib. For a soaked grip, LAMY suggests supporting it nib-down against a soft absorbent cloth or paper towel, allowing water to leave the feed. Avoid pressing the writing tip into a hard surface. Let soaked parts dry completely before storage; the manufacturer's guide notes this can take up to a day depending on conditions. Do not use a hair dryer. Water left in the feed may dilute the next fill, so allow additional drainage when changing to a noticeably different ink color.

Step 7: Refill and check writing on scrap paper

Reconnect the correct cartridge or converter, or refill the piston pen with suitable fountain-pen ink. Secure the barrel normally and test on scrap paper rather than valuable stationery. A few pale initial strokes can reflect remaining rinse water. Persistent skipping can also involve ink supply, nib condition or damage, so avoid repeating aggressive cleaning to solve every symptom. Cap the pen between uses. Before extended storage, empty and clean it, then put it away dry with its components protected rather than leaving old ink to dry inside.
