Washing a cat is always an exciting proposition. You usually look like you walked through a briar patch when you're done. Trouble is, if they get something on them like ink, they'll lick it off no matter how bad it is, so I guess you really had no choice. I'd think something like Simple Green would've gotten out what was left after wiping and brushing.
