Yes, you can clean it with a rug doctor. That or you could probably just scrub it down with a rag. I've cleaned fabric couches many times, it works just fine.
Sorry for the subject change, but I need to ask about cleaning my couch. It's like a suede type material and we've had it almost 4 years(kids+beige suede=very visible stains!) A friend let us borrow her rug doctor. Would it be a bad idea to use the hose attachment on it?
