Erasing Permanent Marker

Have you even walked in and seen a mess like this before? I went to let the dog out and came back to my 3 year old "drawing" on my desk with permanent marker. It was one of those moments that make you just want to scream. 

 The first thought that came to mind is that dry erase markers take permanent markers off of white boards maybe it will work on the desk too.

I colored over all the black spots and said a little prayer then I wiped off the mess with a baby wipe.

I took off most of the permanent marker as you can see, but The downside is that now my green dry erase marker has a black tip. With out a camera flash you can barely see it at all.

Have you ever tried this trick for removing permanent marker?
