So, I tried asking this question on Reddit, and all I got back were trolls and unserious replies. 😒
So, does anyone know how I can remove the sticker residue on these games without accidentally rubbing the factory codes off?
I would press my thumb hard on the card resting on a flat surface and slowly roll the remnants of paper and glue into a small sticky ball - essentially rubbing it clean. It's really rough on the skin, but for such a small surface, that's what I'd do.
