Following Grizzly's suggestions/advice, we:
- Thoroughly washed the car the night before;
- Made a poster explaining the uniqueness and history of 'Car Zero"
- Got there early and got a great slot on the end of a row;
- Removed all non-essential items from the car;
- Showed the car with the top down and the windows rolled down.
Once our Box was parked in it's slot, we then:
- Used "Windex Wipes" to clean all the glass and mirrors;
- Used a lint brush to de-lint all the carpeting and leather;
- Wiped down the entire car with a microfiber towel;
- Ran a baby-wipe over the tires (don't laugh...it works!);
- Brought folding chairs, drinks, and sunscreen.
Of all of these, the lint brush turned out to be the most useful: picking up all the bits of fluff really dressed up the passenger compartment and enhanced the appearance of the car. We actually ended up de-linting the car two or three times to get rid of stuff blowing in the wind.
