I was worried about this as well and found a nice product called CharGon that I've been using since last May, no bristles and it makes short work of cleaning the grill:
I tried them all, it's so simple and works great. It's reasonable cost / build quality as well. I think it's ~$20.00 on Amazon and it's not flimsy and the wood is quality with decent heft. The leather tie it came with failed quickly, but the tool itself will last forever. I've had mine for over a year and a half now. I'm not affiliated in any way other than wishing I would have thought of it years ago.
I won't eat anything off anyone's grill who uses any wire brushes anymore, there's no reason to risk it.
