Hi all, I had a Schmidt 888 cartridge come apart inside a pen. The pen is a semi-translucent material such that you can now see some ink staining. I want to scrub out the inside of the pen with a pipe cleaner. Does anyone know of a good solvent that will handle the black ink that's in there, but not harm the pen material? This doesn't help: I didn't make the pen so I don't know exactly what the material is. It looks like a standard acrylic pearl-flake type material, however. I don't think it's cellulose acetate, which I know tends to react unfavorably with acetone.
I was thinking I'd try DNA. Water doesn't seem to be doing much.
