My hc about Data’s personal routine:
-he doesn’t need showers so he uses a vacuum with different settings to remove dust and debris from his hair, and then cleans it with laundry detergent
-he sprays surface cleaner onto his face and wipes it down with a sponge every morning
-a few times per year he goes through a full repair and polish, to maintain the integrity of his protective outer surface. He always comes back looking super shiny and more confident than the day before
-he wipes lens cleaner with a tiny fiber cloth on his eyes, which disturbs everyone who witnesses it
-He has dust traps that need to be removed and emptied every couple of months. He’s always does this in private because this is very embarrassing for robots
-in contrast, Lore is the guy to just take off his own arm and blow on it like a cartridge before reattaching it
