Not to be Dougie downer here Cate but I find I choose to wash my car very little in winter. In my mind I don't like paying for a wash and by the time I get home its already dirty. You will find the road conditions quite different here with melting snow almost always somewhere on the road. Yup, 5 seconds behind a car throwing up salty runoff and there goes your newly washed $10. I might clean mine 4 times in the winter. Your mileage may vary.
