You could stop every car in Chicago and do a search of the vehicle....unless this is some gal coming back from the laundry-mat...no one is going to have bleach in the car. In fact, if you asked a hundred guys....vast majority will tell you they almost never use bleach for clothing, while a majority of women will admit they use the stuff.
I spilled bleach on my carpet once and ruined it. Stuff is dangerous to have around. I got maybe a drop or two on my hands once and must have dried them on my shirt. Ruined the shirt too.
My wife uses bleach sometimes. The only time it would be in my care would be if I was coming back from the supermarket, which would NOT be late at night.
