The gray suede or whatever thats on our seats are soo thin that a suede brush would damage it. I've always used a sponge with mild soap and water to clean mine. I also covered my drivers seat bottom with a towel or pad to keep my jeans from damaging it. A couple of us have been looking for more of the suede fabric for years with no success. Talk to Lance at the 35th Registry to see if he has had any luck finding some. Good luck
