How to clean a fountain pen with a vacuum-filling mechanismUpdated 10 months ago

This one-stroke filling mechanism makes filling a fountain pen easy and fun. However, the vacuum-fill fountain pen is also difficult to get completely clean. As you'll see in the demonstration video, it might be impossible to get a vacuum-filling pen to look like a new pen after inking it for the first time.

1. Submerge the nib and feed in cool water.
2. Fill the pen like you would with ink, only with the water.
3. Flush out the pen in a sink or separate cup.
4. Repeat until the water inside the pen's body is clear.
5. Let air dry on a paper towel.

The Nahvalur Original Plus, TWSBI Vac Mini and Vac 700R are designed to be detachable at the front section and the back-end as well (a wrench, o-rings and silicone grease are included for such operations) to be thoroughly cleaned and serviced.
