How do you remove crayon from your kitchen table?

Thanks to my little darlings 'missing' the blank white paper completely I now have a table covered with their crayon scribbles (or mark-making as it's meant to be called now).

I can't get it shifted at all!!

Any advice and tips would be most welcome.

There's also some finger paint on the table that didn't get wiped up when it was still wet, would anyone know how to remove it also?

Thank you!
