Have any of you ever used Amodex Ink and Stain remover on a paddington? If so, how did it come out? This would be an old, stray ballpoint ink mark, very faint, about one inch long. My inclination is to just "live with it" but I wonder if anything actually works. It's not a new stain, probably there for quite a while, but I just noticed it...very light, but it's definitely there.
