Just had my first stain on the BN model. Sat it in some juice from my daughter sippy cup all night and had about a 50 cent sized stain on the BN. Picked the phone up noticed it was sticky and turned it over to the stain. Got a rag wet with hot water and just wiped it clean no signs of anything. Even tried looking in threads and between the weave and to my eye I can't see a single sign that anything was there. Very good to know.
