Compound or Method that Can Be Applied onto Cartridge Inner Walls to Stop Ink from Staining It

[Alvin777]

Hi Fountain Pen Network friends, I wanted to ask, if there's anything I can inject onto the walls of a fountain pen's cartridge (not a converter) then flush (it then binds to the cartridges' inner walls) without affecting the ink's performance or the fountain pen, using a syringe because some inks (usually pigmented) stain the translucent cartridges and the ink level cannot be seen?

 

Thank you.

Whatever you apply in that manner could be stained instead of the material of the cartridge body, but if it's permanently bound to the cartridge's wall, and not a sacrificial layer to be renewed with every (staining) refill, then where's the practical advantage?

 

If you're so concerned, perhaps you should look at commercial ink cleaning fluids (at some non-zero cost per millilitre) with which you can remove staining from the cartridge wall should it occur.

 

Even if there is some way to mould an ultra-thin layer of stain-resistant glass all over the interior wall, it wouldn't be something for a hobbyist to do at home, and it would cost more than to simply replace the stained (and already reused) cartridges, which are designed to be consumable and disposable items, as you encounter them — which probabilistically won't happen after every refill.

Not that I'm aware of, but you can use Sailor Do-you as a cleaner.

Thanks for the info.

Stay safe.
