My 1 year old does this crazy crawl where he slides around using semi flat objects under one hand. So he got his grubby little paws on my caseless phone and used it to slide down the hall. Pretttty sure my kids had also dragged some sandbox sand in the house because I now have a number of scratches across the back of my beautiful silver S7 Edge and I want to flush my toddler down the toilet and put myself in time out for leaving my phone without a case. Any way to buff them out?
