Scuffs on back of iPhone 8 that appeared after taking off tech 21 evo Gem case. If you look closely there’s a pattern on the back of diamond like shapes. Have tried just a microfibre cloth, nail polish remover etc. I can somewhat buff them out but they always come back. Does anyone know how to help
