how to get food colouring...?

My dear food coloring causes nerve and learning disorders. You are trying to get it off your fingers but imagine whats its doing to the body. Ever wonder what they are doing in the lab to get this? then we put it in our bodies. Next time try beets or cheeries (red) + blueberries (blue) to get your purple. More natural, safe and healthy. Now, to answer your question give it time and it will go off in couple of days. Don't go trying toxic chemcicals to remove it. It will come off. So the same amount of days it takes to come off is the amt of days it seeps into the blood cells when ingested. One of the many causes why females get severe pain when they have thier period.

I know to get strong odours off your hands, to use stainless steel in conjunction with soap and warm water. You could try that. I would just use a scrubbie, but that may irritate your skin alot. Vinegar, as another person suggested would probably work quite well, as would lemon juice or fresh tomato juice.

Vinegar works well and most people have it in there house. Acetone(nail polish remover) would work in a small amount. Also you could try a little dish soap like Dawn.
