How To Get Rid Of Water Stain On Micro Suede Couch?

I just bought a used couch that has water stains all over it from the previous owner.  The couch was in new condition (all but the water stains).  I thought NO PROBLEM and brought it home.  I used a cleaner I use on my clothes and household - it's called Awesome.  Anyway, that did NOT work.  I was very upset because this cleans everything.  I remember the lady who i bought it from said her sister had the same couch and took the covers and washed them in the washer - I thought it can't be any worse than it looks now that I got ahold of it.  I used a little bit of laundry detergent and the cleaner was already sprayed on it from the previous attempt.  The covers turned out like new.  Now I just have to figure out how to do that to the whole couch (lol).
