How do you remove an ink and a methylated spirit stain from a curtain?

I tried removing the ink stain using methylated spirit and it's left a big purple/blue stain. I then tried a little hydrogen peroxide and now a little patch is bleached which I know is permanent and I'm very upset about itIt also on the day the stain happened i tried nail polish remover. I then got hold of the spirit a couple of days later. Any suggestions of how I can improve this?
