800 miles for a car wash?

Oh wait you have a garage? Okay simple solution. Go to Costco and get a decent space heater.
It might take an hour to warm up and you might have to throw down some towels near the bottom edge of the garage door, maybe even hang an old down comforter over the garage door for some quick insulation, but I've raised the temp not quiet room temp but warm enough to be able to work in just a button down shirt. Get out the buckets of hot water, drop in the no rinse solution and you'll have a clean car for storage.
