Hi Folks  
Hoping someone can help with my 'issue' .. I have light coloured vinyl flooring, with a nasty ink stain. Its from a ball point pen that broke, and was mysteriously covered up.. until I moved a box and found the stain. I've removed a great deal of it with numerous cleaners, but there is still some residual staining. Any ideas?? I've tried "magic eraser", Ammonia, detergents, nail polish remover, and some 'green' cleaner from CTire.
