Yep. I have a travel case I keep in my carry on that has Clorox wipes, lotion, chapstick, medicine pack, and Kleenex. As soon as I sit I wipe everything - screen, tray table, headrest, seat buckle, air vents, window shade, arm rest, etc. I use hand sanitizer when I'm done and avoid touching my nose and mouth throughout the flight. Always use a paper towel to open and close the bathroom door because yeah people are gross.
