Picture of Cleaning Rapidograph reusable pens
Cleaning Rapidograph HELL made easy:
  • Windex
  • 1/4 cup Windex solution
  • Place whole nibs with ink well separated into solution
  • Use Q-Tip to rub the Windex solution inside the plastic ink well. Ink comes off pretty quickly. Wash out with water
  • Unscrew main black plastic housing from around the main inside nib component
  • Swished a bit and within 10 seconds it breaks up quickly
  • Shake the main nib component until the nib bit starts to go back and forth
  • Rinse hot water and hit Windex again until satisfied

I have to use the super permanent ink (film) for the inking I do. So when it dries it is absolute hell to clean.

I cannot tell you how many years I spent using all sorts of garbage. I have used alcohol, 2nd degree burn worthy hot water, soap, oscillators, special Rapidograph cleaning solution, I could go on and on.

I found a random post one day a few months back mentioning using good old fashion Windex. I got off my lazy butt  and decided to give it a go. I am not kidding. 10 seconds and the thing was coming off, unwinding and shaking free ink debris.

They are perfect.

Good to know. I have some of those pens but do not like to use them often because cleaning can be challenging. I guess I don't have to tell you that though. I just looked up what the active ingredient in Windex is and apparently it is rubbing alcohol, although there is also 2-Butoxyethanol in it too, which is an organic solvent for paints and ink. A chemical that may be found in higher concentrations in bug and tar removing products? Look for the CAS chemical number 111-76-2 on products and you may find other pen cleaning solutions. Windex is mostly water.

That is interesting. Isopropyl alcohol might work for most inks, it didn't help with the ink for "film". It might be a combination that is the magic key. I have seen ammonia (also found in Windex) as another suggested solvent to use for the nibs but I am not too comfortable dealing with it straight. Food for thought.
