Is there such thing as a car spray for germs?

I had 2 passengers last night that were hacking and sneezing the whole ride (while half naked in 40 degree weather, wearing cardboard signs around their necks for whatever frat party they were going to). I digress... is there such thing as a spray that I can use in my car to rid the air and surfaces of germs between passengers? Something that doesn't smell like Lysol? 24 hours later, I'm starting to get a scratchy throat and I have no doubt it's from the plague they introduced to my car... probably to all of my other passengers, too.

Thanks!
