Ah! We Americans are determined that never a germ shall meet!
I'd suggest also Lysolling the seats of the diner and lounge cars as well as using wipes on wrapper of the candy bar you buy and the change you get.
Don't forget that when you hand the conductor your ticket, he hands it back. And those door handles!
Our procedure for germ proofing the room is simple. A bottle of 90% isopropyl alcohol, a can of Lysol that we spray liberally in the shower,on the toilet seat, the door handles, and light switches, bed bug spray (just in case) and a few bottles of hand sanitizer. BTW, I do sanitize my hands when I shake the hand of anyone I do not know.. I always say thank you but never shake the hands of the onboard crew. You don't know where those hands have been and does he wash his hands after he wipes his rear? You can really get sick from people like that. Why take the risk-sanitize and kill the germs!
