You need three things:
– scentless soap
– towel
– 1L water bottles. (2-3 if you want)
Fill the water bottles and keep them in your trunk.
When you get back to the car at the end of the day, and are amazingly dirty, the water will be NICE and warm in the trunk for you.
If you want you can transfer it to your water bladder and turn it upside down to provide water pressure and act like a hose.
Then just strip down and take a hobo shower in the parking lot.
Should be plenty warm and now you have soap too.
If you're smart you'll stash deodorant in a bear box nearby.
I bring a hat so that I don't look like a retard since I don't have hairgel :)
