This is a curiosity question. I have lived in SE Texas my entire life and while I have traveled to Minnesota and Canada in January-February I know squat about actually living in the colder climates. Forgive me if it is a dumb question, but how do you keep your cars and trucks clean in the winter? I assume you use some sort of car wash and was also wondering if it washed underneath. I can remember back in the 60's when someone relocated to the south and the cars were almost rotted out. I was in Edmonton once and was leaving to go back to the hotel at the end of the day and the car was covered in snow. Believe it or not I did figure out what the brush/broom thing in the back seat of the rental car was for. Unfortunately I only cleared the windows and made it about three blocks before the snow on the hood flew to the windshield. I am sure the locals got a laugh out of that.
