I've got security screwdrivers thankfully! I'm thinking a very fine microfiber cloth and isopropyl alcohol spray, or otherwise just lens cleaner. I could also try general spray n wipe. Praying I don't ruin it furtherShould be, ive dosassembled a gopd couple clusters before. Remove the cluster, its held together by some security screws (i think star bits) so make sure you have yourself a kit to do it
Its a bummer i dont think ive ever found replacement glass (plastic). Removing the scratches is a pain and not quite the right way to get it clear.
