I am in London if that affects things, although not in a trafficky area.
The washing includes my son's bed sheets, my pants, some socks and my sweatshirt. It was rained on (and completely soaked) by a shower at lunchtime.
I am trying to think why I should rinse it or if I'm ok to go with my instinct and give it a quick tumble dry.
YABU: How disgusting, rinse it at once
YANBU: Bring it in and chuck it in the tumble
