How do you get ink stains off of a backpack?

Pen leaked on my bag and I don’t know how to get it off. Not willing to go out and buy another one since the back was £80. The material of the backpack is Vinylon F if that helps.

Methlyated spitits will dissolve biro ink to an extent. It should reduce the mark but may not remove it all.

You won’t get it off. Why would you need a new backpack simply because this one has ink on it?

Try alcohol, it should work.

Marinate that section of the backpack with milk for a couple of hours in a pan. Brush. Repeat if it doesn’t go away. It must be cow’s milk. Really. It works. Look it up in the Internet. I’ve tried myself and it does work.
