Old finalmouse what do i do with it?

So a couple years ago back in 2021 i bought this cape town final mouse from a friend for a lower price since he broke the side buttons. I tried customizing it with spray paint and hyperglides but it turned out HORRIBLE the paint kept coming off and mixing with my palm sweat n all that and i kinda just delt with it until i got a new mouse. I recently was looking around my room until i found my final mouse still messed up but im thinking maybe i can restore it somehow? Any ideas? i really need to figure out how to clean this thing 🤣🤣
