During my studies, I bought a Rotring S0699570 Rapidograph College Set 4 in November 2019 – and I have not used it once since.
Part of this six-year stretch of non-use was that I simply had too much on my plate. Health issues, mostly. The only thing I ever managed to do with them was clean them.
Which is exactly what I am doing today – and of course, it reminded me of all the other times I had done the same.
See that Tweet from 2022?
I pulled it from a Twitter data archive I requested some time ago.
From memory: inside the cap is a small, soft ball that the nib pushes against when you screw the cap back on. And if memory serves me right (and when it comes to criticism, it usually does), I think I once used more force than I should have – out of inexperience. Out of attached meaning. Out of how expensive the set was.
While syncing my archived Tumblr posts into OneNote, looking for the last time I wrote about cleaning these pens, I decided to write this as a warning.
Back in 2019, Rotring Rapidographs were already a rarity – almost a novelty gadget. Between glowing reviews on German Amazon.de (mostly from before 2015) and seeing some artists in books in my library use these pens, I bought the set.
I bought something because of hype. I bought something because if real artists and if real designers use this product, then, haha, surely that purchase will turn me into a real artist, into a real designer myself!
And here’s the problem: finding replacement parts has become difficult. The nib I suspect is faulty seems to have a damaged capillary system – it drips ink, so the first mark on paper is blotchy. Always.
Last week, when I visited boesner here in Stuttgart, I also checked for replacement Rotring pens. Not just nibs, but the whole pen – because I had a feeling about how scarce the parts might be.
They didn’t have any Rotring products at all.
So I bought Microns instead. Mass-produced, mass-used, disposable — the Bic biro of fineliners.
And now, this Monday after that Friday, I’ve made a foam bath for my Rapidograph 0.25 mm cap, nib, and holder, and I’ll just let it soak.
Maybe that will fix it. I have no idea. I am basically ready to move on from using them, see below why.
Because what I really need to let sink in is this: what I thought was an exclusive, prestige product – something I probably bought as a therapeutic measure against impostor syndrome – was truly exclusive only in the sense of market scarcity.
At the end of the day, working with gold leaf might give you a feeling of prestige, but you are still just gluing gold to paper for an effect.
If you ask me, go with the cheap, available, mass-produced. Because otherwise it will be six years later, and you’ll never have had the nerve to use your “prestige” tool — because of all the meaning you’ve attached to it.
And in this case: throwaway beats sustainable.
Here is my chat with ChatGPT about if I can fix this, and how:
Me: So, what do YOU think? Did I damage the nib?
ChatGPT: If it’s a Rotring Rapidograph 0.25 mm and you remember pushing the nib hard against the cap’s sealing ball — it’s possible you did some damage, but not necessarily the kind that makes it permanently unusable.
Here’s the thing:
The sealing ball inside the cap is meant to lightly touch the nib to keep ink from drying. If too much force is applied when capping, the tubular nib can bend very slightly or the delicate internal wire (that prevents clogging) can be displaced.
If the wire is even slightly bent, it can cause blotchy starts or dripping because ink flow isn’t being regulated properly.
The capillary system in these pens is very sensitive. Dried ink inside can mimic “damage” symptoms — so what you’re seeing might just be stubborn clogging rather than actual deformation.
Real damage (crushed tube, bent wire) usually results in either constant dripping or no ink flow at all, even after a thorough clean.
A good test:
Fully disassemble and soak all parts in a gentle cleaning solution (Rotring’s own, or a water/ammonia mix for stubborn ink).
Dry completely.
Load with fresh ink and test on smooth paper. If it always starts with a blob after sitting capped, but flows normally after a few strokes, the issue is likely internal clogging rather than a bent tube.
If it drips even mid-line, then yes — the nib is probably physically damaged.
Replacement nibs for Rapidographs are scarce but not impossible to find second-hand, though you often have to buy them from collectors or surplus stores.
If you want, I can show you how to visually check for a bent Rapidograph wire without special tools — it’s a very quick at-home test. Would you like me to walk you through that?
Me: Yes, please.
ChatGPT: Alright — here’s how you can check your Rotring Rapidograph nib for damage without any special equipment, just patience and good lighting.
1. Set up your inspection space
Work on a clean, bright surface.
Use a desk lamp or bright daylight. A magnifying glass or phone camera in macro mode helps a lot.
Have a soft, lint-free cloth or paper towel ready so the nib doesn’t roll or get scratched.
2. Remove the nib section
Unscrew the nib assembly from the barrel carefully.
If there’s still ink in it, rinse it first so you’re not working with wet pigment.
3. Identify the parts For a Rapidograph 0.25 mm:
The tubular nib is a very fine metal cylinder.
Inside that tube is a hair-thin wire (the ink control needle). It should be perfectly centered when viewed head-on.
4. The centering test
Hold the nib so you’re looking directly at the open end (straight down the tube).
The tiny wire should appear exactly in the middle of the circular opening.
If it’s touching one side or visibly off-center, it’s bent or displaced.
5. The spring return test
With clean hands or a toothpick, gently press the wire inward from the tip (barely a fraction of a millimeter).
It should move smoothly and return immediately to its original position.
If it sticks, feels rough, or doesn’t return, the wire is bent or its housing is clogged.
6. The straightness check
Rotate the nib slowly under good light.
The tube itself should stay perfectly cylindrical — any flattening or oval shape means the cap’s sealing ball probably crushed it slightly.
What this tells you:
Wire off-center + sticking → likely bent from force, repair is tricky and not always reliable.
Tube oval-shaped → mechanical deformation; may cause permanent flow issues.
Wire centered but slow return → probably dried ink deep inside — can often be fixed with extended soaking and flushing.
If yours only has the blotchy start but passes these visual tests, you might just have micro-clogs rather than true mechanical damage — which is actually good news, because those can still be cleaned out.
If you want, I can also give you the safest deep-soak cleaning method for Rapidographs that dissolves even old dried ink without damaging the wire’s delicate spring. That’s the step I’d do before declaring the nib “dead.” Do you want me to prepare that cleaning guide?
Me: I hope I have the things at home I need for cleaning
ChatGPT: For a safe deep clean of a Rotring Rapidograph, you don’t actually need exotic supplies — just a few common things (and one optional item that makes it easier).
Here’s the list of what you can use:
Required:
Distilled water (tap water can leave mineral deposits in the capillary system)
A small container or shot glass for soaking
A drop of mild dish soap (unscented is best)
Lint-free cloth or paper towel
Optional but very useful:
A small syringe or bulb pipette (for flushing water through the nib from the back)
Household ammonia (clear, unscented, about 5–10% strength) for stubborn dried ink
Rubber gloves (to avoid getting ammonia or ink on your skin)
If you tell me what you have at home, I can adapt the cleaning method to work with your available tools — especially since ammonia handling is optional but very effective for clogs older than a few months.
Do you want me to write the step-by-step cleaning process now, or should we first check what you already have on hand?
Me: Brushes for water color, dishwasing liquid, warm and cold water, hydroperoxide
ChatGPT:
Got it — you’ve got the basics for a safe cleaning, though I’d skip the hydrogen peroxide (H₂O₂) because it’s an oxidizer and can corrode the fine steel nib and spring over time. It’s not recommended for metal pen parts unless you’re deliberately trying to strip something.
Here’s the safe step-by-step cleaning method with what you have:
1. Disassemble the pen
Unscrew the nib assembly from the barrel.
If there’s ink in the reservoir, empty and rinse it.
2. Prepare the soak solution
In a small glass or ceramic container, mix 1 cup warm distilled water with 1–2 drops mild dishwashing liquid.
Stir gently to avoid bubbles — we want a wetting solution, not foam.
3. Soak the nib
Place the nib assembly tip-down in the solution.
Let it soak for at least 1 hour for recent clogs, or overnight if it hasn’t been cleaned in months/years.
If you’re impatient, you can swirl the water gently every so often.
4. Gentle flushing
If you don’t have a syringe, dip a watercolor brush in the soapy water and touch it to the back of the nib assembly — capillary action will help draw water through.
Gently flick or tap the nib on the edge of the container to encourage ink to come out.
5. Rinse
Rinse thoroughly in cold distilled water to remove all soap.
Make sure no bubbles remain inside — you can draw water into the nib and let it drain a few times.
6. Dry
Stand the nib assembly tip-down on a lint-free cloth or paper towel until completely dry.
Avoid blowing air directly into the tube — moisture + breath oils can encourage rust.
Extra tip: If, after soaking, the ink still won’t clear, you can replace the warm soapy water with a 50/50 mix of distilled water and clear household ammonia (if you get some later). That’s the classic technical pen cleaning solution, because it dissolves stubborn pigment residues without harming the spring or wire if exposure is kept under 30 minutes.
If you want, I can also give you a quick wire movement test to do right after cleaning — it’ll tell you in 5 seconds whether the nib is healthy enough to keep or worth replacing. That way you’re not left guessing. Want me to add that?
Me: Can you give me the links to the sources for these processes?
