On the topic of washing your vehicle thoroughly afterward:
We'll be renting an RV for use during LDRS. I've determined that the Blue Beacon Truck Wash (2020 S 900 W, Salt Lake City,
Salt Lake City, UT | Blue Beacon Truck Wash ) has a floor-mounted unit that is designed to pressure wash the underside of vehicles. The manager told me that the solution used contains a "special chemical" (he didn't know what it is) that is particularly helpful in removing salt accumulated from being on the Salt Flats. I will take our RV there on the way back to the rental agency, to ensure I have no problems returning it. While nominally a "truck" wash, they do smaller automobiles too.
