New Noodler’s Flex Pen Cleaning

Since the release of the latest Noodler’s flex pens, I’ve had several people emailing me mentioning that they were having trouble getting their new pens to flow properly. They tried shaking, pushing the ink down the feed with the piston, and dipping the nib, but to little avail. Nathan mentioned in a previous video about his Ahab pens that the new feeds on the flex pens may have residual oils from being machined that can cause flow issues. It’s not every pen that will be affected, it seems that most are fine and some are affected.

In any case, it’s a good idea to go ahead and flush your pen out before inking it up, just like I show in the video here. Just use water, dish soap like Dawn, and a bit of ammonia. Flush it with clear water after that, then you should be all set. If that doesn’t do it, then the friction-fit nib/feed may need a bit of adjustment like I show in this video.

I hope this helps! If you have any further questions, just post in the comments or shoot me an email.

    Important to add:
    Flushing any new pen (even if it costs $500) before using it, can save you a lot of headache. Residual oils can be left on any feed from any pen from any manufacturer.

    I loved the cups!

  • Definitely! It's always a good idea to flush a new pen, no matter what the price. I'm glad you like my cups, super fancy!

    Can I detach the whole pen then put it in a ultra sonic cleaner machine with some detergent like normal hand-use mild dishwashing liquid?
    It's hard to find ammonia, thank you.

  • Yes, that would do it! It's really just the feed that you need to clean thoroughly, though. The rest of the pen should be fine, but it's the cutting oils left over from the machines that cut the feeds that cause potential flow issues. 

  • I think this advice should apply to any type of fountain pen, not just cheaper ones. It's really worth giving it a thorough cleaning before you ink it for the first time.

  • You are exactly right about that. A thorough cleaning is never a bad idea for a new pen of any price! The reason I did one for this pen in particular was that Nathan told me that cleaning was almost a must, not just a recommendation. So I made this video to make it a little easier to show how to clean it for someone that's never used a fountain pen before. This same type of practice can be used on any pen though, it's not just for Noodler's flex pens.
