Removing Ink from a Velour Chair?

My 1 year old got black pen on a velour chair. Someone said to use Tide in the wash. I am assuming that the Tide can be diluted or just used directly on the pen mark on the chair to remove by rubbing lightly with a clean cloth. The cover can't go into the washing machine.

Will this work or is there some other way I should be trying to clean this off? Thanks.
