Yes, the dustless chalk does leave an oily residue which is hard to remove. The reason for this is because in order to rid the chalks of dust producing qualities, moisture needs to be kept in the chalks. I recommend Mr Magic Eraser or a regular cleaner is fine. It needs to be something soapy to break through the grease.
