You wil need to use  a stong solvent. I would try going to where they sell paint and find a heavy duty solvent which would be a paint remover.  You can use flour as a poultice

My son decided it would be a good idea to draw something on a friends honed marble floor, magic marker which he thought was erasable ink. I have only made one attempt, lacquer thinner and paper towel poultice. Not much difference. I am still trying to source materials here in Australia, not easy. Help me out here Fred! Is a jar of commercially available poultice any better than a home remedy. What should I try next. I think I could get DE easy enough.
