Welcome OP!
I'd use something like this.
http://www.amazon.com/Sno-Brum-Origi.../dp/B0007LDXLA
Won't leave scratchs, and gets the bulk of the snow.
For the smaller spots where the SnoBrum cannot go, I have a Snow Brush that has Microfiber tipped bristles which are very soft. However, I cannot find them online.
That may be an option for you.
