Permanent texta on labcoats

[ri]

Hi All,
we have some permanent texta on lab coats. Striking whilst 'the iron is hot', does anyone have any idea how to remove it?
Bleaching doesn't help.....

Apparently blotting with acetone works, you should place paper on the underside to prevent bleeding or also I heard hairspray works.....go figure. Worth a try.
