Was thinking about a possible way to reduce the odor smell when using the A/C

[Yaris Hilton]

One thing that helps is to never turn the car off with the air conditioner or recirculating air on. At least a half minute or so before shutoff, I switch over to the plain vent setting with outside air coming in, to dry off some of the condensed moisture on the evaporator core. Good idea in any car, not just a Yaris. I don't like driving around with a smell like cat pee blowing out of the vents, coughing from mildew spores.
