Hello All,

I am thinking to use the Koh-I-Noor Rapido-Eze Pen Cleaning Concentrate for unclogging the nib with carbon ink stuck. I just want to make sure if this liquid has no harm for metal and plastic parts of my very previous pen. Any thought or experience using the concentrate will be appreciative. Thank you for your time!

It's safe. But if you want to be really really really sure, tell us what kind of pen you have. I've soaked all sorts of stuff in it, but i suppose there might be some sort of material that you want to avoid getting near the solvents. I can't think what that might be though...

Who are the pen shops in your neighborhood? Find out or tell us where they are, at http://penshops.info/

It's safe to use with hard rubber, celluloid, polystyrene, acrylic. i.e. just about anything used in a pen. The only material that I would avoid is casein. But that's because water, not just the pen cleaner, will damage the material.

 

Rapido-eze is the best and safest cleaner to use for stubborn ink, and for removing India ink. For the later, use full strength.

I just bought two bottles on the basis of all the recommendations here.

I have a number of pens that have been in storage for quite a while

and are not stiff, scratchy or simply unable/unwilling to write anymore -

which I'm hoping is due to the caked ink issue I've been reading about here.

Question: how long should I soak these pens? Approximately speaking, of course!

Thanks in advance.

Yes, so how should one use this cleaner? I don't own any kind of ultrasonic cleaning machine.

 

Can I just let fountain pen suck up Rapido-eze like it does ink and let it sit in the reservoir and feed for about a minute and then pump it back out?

As broadcast engineers like to say, when all else fails, read the instructions.

I heard about Rapido-Eze a number of years ago and then this thread prompted me to send for some. I used it today on a cap that had a good deal of dried ink in the cap and which didn't come out with water in the ultrasonic cleaner. With a one to four solution of Rapido-Eze the results were amazing - absolutely clean with no trace of ink left. I am sold on this product!

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
