..and going, and going... just like that bunny.
If the marker/sharpie is fresh, alcohol, or lighter fluid should do it...you may have to use both, since sharpies are chemically a combination of colors (the black is, anyway) and sometimes the separate colors (typically red + green or cyan=black) have different solubilities. Sometimes just soap n' water will work.
As the mark gets older it seems to get tougher, so you might need a more 'active' solvent like acetone. Sooo...
In this order:
1. spit + a tee shirt,
2. soap n' water,
3. zippo fluid,
4. rubbing alcohol ( or better, denatured alcohol),
5. acetone.
If none of that works, you'll have to get agressive, with Cameo or Bar Keepers Friend, or Comet...but this is usually not necessary.
In the future, use a "dry erase" marker, as said before...it'll just wipe off easily.
End of story, for me anyway.
