Does anyone know how to remove RediMark black permanent marker from skin? We used it for a costume and colored the skin? It seems to have come off with soap and water with much scrubbing. It is an older RediMark, so I'm worried about it being a little toxic, any side effects? headaches, dizziness, etc.? I reviewed the marker for directions and/or caution remarks. It said nothing about being toxic, but still, I wonder. I'd really appreciate some info. Also, how do you remove if from white cotton material (e.g. turle neck sweater)? Thanks!!!!!!!
