From it I learned that the remedy for ballpoint ink stains is glycerine. I once had an old bottle of the stuff that worked wonders, saved a yellow linen shirt that I paid way too much for and was almost ruined by an inky gash across the front.
I used that old bottle until I couldn't anymore, but I regret to say that the new stock I ordered — proudly described as vegetable glycerine — isn't nearly as effective. I scrubbed and scrubbed and managed to mute the stains slightly, but the ink stain isn't gone ... and probably will never be.
I tell myself it doesn't matter. Ink stains are a badge of courage, not a blot of shame.
