I recently got my surface pro 3. Been with me for a week now. I use the surface pen every single day to annotate my lectures. I like to keep my SP3 in a horizontal position on the table without opening the kickstand. I just noticed that a few scratches started appearing on the back of the SP3. I'm assuming its due to the fine dust particles on the surfaces of the tables I use. I try to clean the surfaces as much as I can. Does anyone have a quick fix for this before more scratches appear ???
