It’s really not that much work. Just completely disassemble the mouse, put the shell in your ultrasonic parts cleaner for 30 to 60 minutes, then dunk in plastic-safe disinfectant solution. Rinse with deionized water, dry with filtered compressed air, and reassemble. I keep 3 in rotation so I always have one ready to go and another in reserve.

If you can’t afford to invest 2 hours in basic maintenance each night maybe stick to whatever came with your prebuilt Costco PC.
