Many thanks to you both. Will try white spirit initially. I had been wondering whether or not it would react with the perspex but will wipe excess off immediately.
WD40 is also good for removing stubborn marks, but whatever you use, it is always best to try it on a small inconspicuous area first, especially if using white spirits/turps which might react with the plastic.
