Depending on the weather touches car washes are available. Using something similar to a final rinse option may be a possibility.

In Winter, I just wait for a day at 50 degrees - even if it's at that temp for just an hour or two in the afternoon. In MD, we'll get a surprise day that attains this temp once or twice during the Winter months. There's nothing like a hand-wash with good products. I've tried a touchless car wash once, and as a last resort, that's OK.

We just need some freak'in warmer weather! Can't wait!!

Canadian winter doesn't get that warm for months. We'll have weeks where the temperature is -30° C which is -22 F

Damn.
You dudes are a hardy bunch!

no thank you!
it was -10F the a few nights ago.. first time in Jersey i can remember getting that cold

AMMO NYC has a awesome video on their youtube channel that's helped me out. Search it up.
Think the easiest way would be the pressure washer. It doesn't get your car as clean as a full clay and bucket system but it gets it through the winter. Depending on how dirty and how often you've cleaned it, there's usually a thin layer of dirt on it still.
If you're doing the traditional bucket, wear all your normal winter clothing but have your latex gloves for precision and KEEP YOUR SOAP BUCKET FILLED WITH WARM WATER! It's actually super enjoyable to wash it outside even in -15ish weather this way.

I washed my car every shift I worked when I worked at Acura. My Civic used to be clean 24/7 lol.. now.. my BRZ this winter is now white xD

So is mine, but then again it did come out of the factory white ; )
