Rotring Cleaning Fluid For Drawing Pens 100 ml, White

I found my grandparents old isograph rotring pens which are probably about 60+ years old and haven’t been used for 30 or so years. Brought the cleaning fluid after nothing happened from soaking the nibs in hot soapy water for a few days. Put the nibs is a dish and covered with just enough fluid and left for about 18 hours. I changed the cleaning fluid twice during this time. The pens now work like brand new pens, you’d never know how old they are! I’m so happy with it. Would 100% by again

Good cleaning fluid, it works wonders.

Quite expensive for what is probably close to being a small bottle of white spirit. But, it did do it's job well.

l like it very much

Not too sure what is in this liquid. It is colourless and odourless. I bought it to clean up my set of 8 isograph pens which have lain unused for at least 15 years. The thicker sizes were easier to clean taking only a few days of soaking and rinsing. Smaller sizes, 0.5mm down to 0.25 were very stubborn and took nearly a month. Only one pen, the 0.18, was beyond help as the wire inside the nib refused to move and then snapped after excessive shaking!So not miraculous results and much persistence and patience needed. Probably just as effective to use a mild, warm detergent solution which would be a lot cheaper!

I don't normally get too excited about such mundane little bottles. But in this case I wish I'd discovered this stuff some time ago - like when I threw away a complete set of Rotring Drawing pens after I thought they had expired.Like, I suspect, most owners of these fine drawing instruments, I rigorously cleaned and flushed through the pens between refills. Flushing was normally warm water with a spot of liquid detergent. And this seemed to keep the pens in pristine health until slowly the finer nibs would start to become scratchy. Likewise I use fountain pens - Parker is my favourite - and by only using manufacturer's inks I considered these to be almost self cleaning, with only the odd flush through needed.So when my latest set of Rotring drawing pens dried out accidentally, I tried this cleaner to get hem back to life. I did the usual warm water flush and clean, and then filled the ink reservoir with this cleaner and left it for a week. Suffice it to say that the effect was dramatic, and when drained and filled with black ink once again the pens were restored to "as new". I then tried putting a few drops on the nib of my Parker when the ink expired - the effect that it had here was even more dramatic with the full flow of the ink restored when refilled (and even better as the tip of the nib was "broken in".Tiny bottle, but should last years. Thoroughly recommended (much to my surprise!).

It works but is a expensive way to clean the pens. It does a better job than water but in order to soak it in a small bowl you need to use a very small one for the nib otherwise you will use a lot of the product and will be a waste just for one pen.

Value for money
