Washed mine in the mid 30s. Didn't dry it off at the car wash and it froze on the drive home.

I hate it when you wash and then the dew point happens. You just can't dry the damn car!

Probably low 40s for me. I love using Optimum No Rinse with warm/hot water to keep the hands from freezing.

A wise friend of mine once said, "just because it's cold doesn't mean it's less dirty." I always wash it when it's dirty :tup:

I used the bay this weekend and by the time I got back home, my doors and froze closed :icon17:

Oh ****? How about Windows? Did you try rolling them down?

It's 37 degrees right now at my house and I'm headed out to wash my car. Not too bad. I always use hot water from my garage sink. Wish I had the heated garage and floor drain thing. I've got a fridge out there too so with heat and a drain I'd never have to leave.
