ABS shine is only bad if you don't treat your keycaps well. I use a normal big sized brush to wipe off visible dust a few times an hour. I wipe it down with 70% isopropyl alcohol and a microfiber cloth (I use the Zeiss eyeglass cleaning cloth because I know that won't ever accidentally rub too hard). I do this once every hour on my keyboard. Dust and gunk can get abrasive so brush and wipe that shit down NON STOP
