Alumilite ink stain question

[The shed Dxb]

Hey All,

Had a customer that I met that purchased one of my bespoke fountain pens made with Alumilite resin.

Some highly pigmented ink was used and left for an extended period of time and apparently it stained the Abalone style colouring on the resin.

He mentioned he tried water and even an ultrasonic cleaner and it didnt come off.

Haven't had a chance to test it but Any thoughts on how it may be cleaned off or even if is possible with denatured alcohol or mineral spirits.

Thanks

Hmmm, I have to wonder if the ink was actual water based fountain pen ink? I put a section in my ultrasonic that had black ink all around it from filling my pen, the ink came off immediately so I dumped my ultrasonic and filled with clean water/solution. That section had been sitting around probably a month with ink on it and it's fine now. Is it possible it wasn't water based ink?

And my similar story must have been a pigment based ink, as the ink did not come out no matter what I did - water, ultrasonic, DNA, mineral spirits and other things that I thought would have the least chance of damaging the resin of the blank.

I ended up just re-turning the blanks. Though it was a not-very-expensive blank so it wasn't a big sacrifice.

Before trying solvents such as DNA, mineral spirits, acetone, or stronger - I would try old fashioned "pen flush". There are a couple of proprietary ones on the market here in USA (I've used J.B.'s Perfect Pen Flush, and Indy-Pen-Dance stock one which I haven't tried yet). I suspect it's distilled water with a couple of drops of detergent and a dash of ammonia (based on the slight foam and the smell).

I force it through the section with an ear/nose bulb syringe, repeating many times until a rinse with distilled water flows clear.

Appreciate the help everyone, knowing the customer it is probably pigment based.

Will see if I can try out a pen flush solution.

Thanks!

Some inks can permanently stain resins. Noodler's Bay State Blue is one of them. So, you may want to adjust your warranty accordingly. There are probably others, I don't know. But, from what I have read Noodler's Bay State Blue is notorious.

Then pen flush recipe I use is 10:1 distilled water to household ammonia and a couple drops of dish detergent. Very cheap to make.

If there are no metal parts (like tubes) on the stained part, you can try a bleach solution. But bleach and metals don't play nice with each other.
