i never wipe my phone with anything usually. not even with microfiber cloth. i just rinse it with water real quick and wipe some of the water off with my hands and let it air dry..have had mine since launch day and been fully naked and still no major scratches, only little tiny micro scratches on the stainless steel but its expected and its not a bother... soo im curious, how do you guys keep yours clean? and how do you clean it? do you think wiping with any kind of cloth will scratch it?
