While my Smart Keyboard is currently shiny and new, I know it won't always be like that. Poked around to see if anyone else talked about this and didn't find any other posts. Does Apple have a specific instruction on how to clean this keyboard? It feels like some kind of fabric material. I'm assuming a damp magic eraser and a bit of soap to degrease but am curious to hear what others might think. How will you clean your keyboard?
