Cleaning your felt-tip pen
Unscrew the barrel from the tip section.Rinse the tip by filling and emptying it with water (repeat this until the water is clear). Caution: Ink residue will flow out.
If the pen uses a cartridge/converter, place the tip section into a beaker or other container of clean water and let it soak overnight
The water level should completely cover the tip.
Be sure to use room temperature water. Distilled water will work best (tap water sometimes contains particles which may clog the feed). Never use alcohol, as it will damage the feed or other parts of the pen.
Let the tip soak for 10 to 15 minutes, then blot dry with a paper towel. Soak the tip overnight if necessary. Wash your pen every few weeks or whenever changing ink colors.
