If the mark was caused by "iron" or the chemical element Fe as an ocide than oxalic acid is the normal "spotting" chemical used by drycleaners.
If as one would expect its just "burnt" then thats carbon. In theory Carbon Disulphide might help if I remember correctly but in view of the low cost of sheets I would advise buying a new one and using the marked one as a dust sheet for decorating etc.

I have lots of rather technical methods which are well beyond anyone else to manage to understand. You'd all get yourselves into trouble. So I'm only prepared to give a HINT
