Hey folks, Does anyone have a recommendation for tools to clean a 5S with? When I bought my space gray model, it had an almost filmy finish to the back. The aluminum was so, so clean lol. The screen was also incredibly clean. I've used tips from that chick on Youtube like using a microfiber cloth and I use a product to clean screens for the front. But what about the back? And are there any specific products or kits meant specifically for the 5S? Thanks everyone!
