Well, I have scrubbed for two days with a tooth brush, but all the ink is gone! If any of you find that the pen you are chewing is of poor quality and leaks ink when you bite the end off, I can vouch for the Amodex spot remover. It took a while, but it really did remove all the ink from Mommy's rug. Just be sure not to try to wipe up the ink with water first. Water sets the ink and makes it impossible to remove. The bottle says that Amodex works for other stains too, like permanent ink, grass stains, red wine and make-up. I'll let you know when I try it next time.
