Staedtler Marsmatic 700: Tehnical Drawing Pen Maintenance
Greetings peoples,
Anyone had any luck reviving Staedtler Marsmatic 700 technical pens that were put away dirty and not used for a while. I just got my hands on a set of seven (retails for ~US$150) for $10, and have so far tried taking them apart completely and washing them in soapy water. So far I'm getting some gray, watery ink from the tight spaces I couldn't dry completely, but no or very little ink is flowing from the cartridge. Any ideas?

I bought Mars Staedtler stuff 30 some years ago when I took a commercial art class. I have the compass maker, been in the box all this time. I guess that makes me a hoarder, huh?
So i' understand
Take the whole pen apart including the ink reservoir from the handle, and the little black piece (holds a very thin wire) from inside the nib.
Simply soak in a cup of warm water for a few hours to rehydrate the ink.
Then, hold each of the various parts securely between thumb and forefinger and shake any loose ink chips out.(do this over a sink of water so as not to loose or damage a part if dropped) Keep rinsing and shaking until water is clear. I ended up using a fat bamboo skewer's dull end to vigorously pump some water up and down in the ink well to get the sludge out. Careful with the little wire thing when you put the pen back together - it will eventually find its way back to the center of the nib. Pens have color coded parts so as not to mix it up. If the pen is nice and clean, you will hear the familiar clicking as you shake the pen to start it.
. I used to think that ppl who paid so much money for high-quality writing/drawing instruments were crazy ... until I tried a few. I guess it's like with everything else - good tools do make a difference.
