I'm not sure if my suede fabric is the same as yours, but it seems to clean really well with just plain water and a rag. A few times I have used a bit of mild soap, followed by clean water and that's it. It seems to release dirt and scuffs really well.

We had some stains on the side panels from a window leak and we used a carpet spray cleaner to take the stains out. Worked very well and does not seem to harm the fabric.
The particular brand we used was Zep High Traffic Carpet Cleaner from Home Depot.
