For future reference, start by trying just plain water. My daughter decided to use a blue ballpoint pen to decorate our microsuede couch (she wasn't smart about it...she signed her name so we knew it was her!) I was so upset. I tried plain water to start, thinking that at least it wouldn't hurt the fabric. It took a bit of scrubbing, but the marks were removed within a minute or so. And then I just gave the surface a good rub after it had dried. You can't even tell when you look at it that it was ever drawn on. Microsuede seems so easy to maintain.
