Glass Pens Can Stain?

[jfp]

Why did no one tell me this? I assumed that glass is fairly nonporous and most inks would wash off. I used Organics Studio Accident Blue and there's a tiny bit left that I can't get off.It's a nice blue so I don't mind so much but I like my pens clear....I'm cleaning it with Organics Studio's cleaning solution and leaving it in to soak but not much results... Any ideas?

Try using a toothbrush or try something a bit sharper like a bleach solution. The accident is actually a pigment ink so the glass is not stained in like colored, it's just that blue particles are sticking to whatever micro scratches the glass might have. In the worst case use some acid to burn the ink off, glass is very resistant to most acids the ink particles probably not so much. I know the effect from my demonstrator pens, the pigmented inks "stain" like hell, but a good scrub gets everything away always.

Dipping it into the solution seemed to have worked. Thanks for the advice though!
