Kitchen towel trick - keeps your shirt clean
Here's an idea - to keep a dress shirt collar clean of dirty air and highway exhaust soot, take a soft "flour sack" kitchen towel, like these
and tuck it in and over your collar as protection. It's also great to have with you. It's softer than a paper towel and just as absorbent, if not more. I clean my glasses and sunglasses, use it as a napkin, clean my helmet shield or camera lens... very useful.
I fold mine over once at the corners, in a triangle bandit shape, flip it over my head and then tuck it in from behind, and over the top of my collar. It's also good for cold weather as it provides an extra seal from the wind when used with a scarf. I have been doing this for about 10 years. I can't get away with a light-colored dress shirt on a bike without this trick. Not even for a short ride. If my leather jacket doesn't smudge the collar, then the dirty air or my Guinea oils will.
