Seat Microfiber Couch

cleaning microfiber swade?
i have a tan microfiber swade couch and Love Seat set, and i was wondering how to clean them w/o damaging the fabric? I have tried to clean them with soap and water but they always leave dark circles where i clean them, and it looks horrible! I have a two year old little girl too, so I’m always cleaning them.m Does anyone have any advice on how to clean them with out leaving water marks or damaging the material? I want them to look new again.
Do you have them Scotch guarded? If not, you should get that on it…I’ve got two boys (4 and 6) and my tan couch had taken a beating. I had it scotch guarded when we bought it. Since, I have a cleaning company come out and clean the cough once a year. Usually before Thanksgiving so it looks nice when company comes over for the holidays. My cough looks great even after all the spilled sippy cups, mark wars, pop tarts mashed into it, etc. Hope that helps.
