Wheel Well Liner

Does anyone know what material the wheel well liner is? It feels like some sort of felt material. I would like to know so, I can clean and protect it properly.

As far as I know, it's some sort of felt. I spray with semi hard pressure from garden hose. From time to time, I use a soft bristle brush. Its seems to be very similar to the product they used in both my 2014 BMW's. I've never had an issue with them.
