Step-by-Step Instructions

Step 1: Disassemble the Fountain Pen

  • Carefully unscrew the barrel and separate the nib and feed from the pen's section. If your pen has a cartridge or converter, remove it as well.
  • Note: If your pen's warranty does not permit disassembly, consult the manufacturer's cleaning instructions.

Step 2: Measure the Pen Flush

  • Use desired amount of pen flush (normally 18-20 ml) and pour in a cup or a bowl.
  • Ensure you're measuring on a flat surface for accuracy.

Step 3: Soak the Pen Components (optional)

  • Pour the flush into a cup or a bowl.
  • Submerge the disassembled pen components into the pen flush and let them soak for a few minutes. This will help break down stubborn ink residues.

Step 4: Rinse with Clean Water

  • After cleaning with the pen flush, rinse all pen components with clean, lukewarm water. This will remove any residual cleaning solution.
  • Ensure you rinse thoroughly to avoid any lingering pen flush.

Step 5: Dry the Pen Components

  • Gently pat the pen components with a lint-free cloth or paper towels to remove excess water.
  • Allow all parts to air-dry completely before reassembling the pen.

Step 6: Reassemble the Fountain Pen

  • Once all parts are completely dry, reassemble the pen in the correct order.
  • Make sure everything is secure but not overly tight.

Step 7: Test the Fountain Pen

  • Test your pen on a piece of paper to ensure the ink flows smoothly. This will confirm that the cleaning process was successful.
