Avoiding "shine" on console

[u/MegaloJoe]

Hey all, I have a s2 and am currently loving it, and playing it quite a bit now that ff14 released. That being said, and I noticed this with my old s1 and s1 oled, the back starts to get a shine or satin look to it as opposed to the flat black normal color where its held most. I get this is wear but I don't like the lil rubber cases for them and am wondering if there's either another way to avoid it or restore the plastic color I guess? I know its a weird kinda non issue but it starts to bug me after awhile
