Pencil on the fabric inside of the door!

So my 5 yo son decided to take the pencil from mini golf tonight and draw on the fabric part of the inside of the door. So I was wondering if anyone on here ever had to deal with that? I Googled and read a few things but figured I would ask on my go to site and see if anyone knows a sure thing to get it out. Thanks in advance

 

eraser!

actually i think soap and water may work, its just graphite

 

I have read that an eraser might work. But they say soap and water does'nt do sh*t. You would think it would come right out but it actually stains pretty good.

 

at least its a good excuse to do the leather armrest mod
