My friend used to take his to a self car wash and rinse his car off with the soap and pw and just drive back home to actually clean it with onr in his parking spot. Options are very limited for sure.The key to my statement is "If you love to wax". The high ph levels of the auto carwashes will have fun with your work, and you'll have to keep waxing and waxing and waxing. Not to mention the dirty water filled with contaminants that many have, like our local ECO wash that uses recycled water. Water spots, some etching after awhile, it's a hot mess. In the winter, my only real choice is to grin and bear it, or get some foam shampoo and use only the hp wand . We have one locally that is cheap, and lots of pressure. I avoid those that greet you with brushes right at the entrance, or those spinning foam mechanical cleaners that are filled with the previous 1,000 cars dirt.
Daily driver without a garage, choices are somewhat limited.
