i wash mine at the .25 diy car wash. this works great for the wheel wells, underside & engine. a quick dry down and i head home on the freeway for the much needed crevice drying. i let the car set overnight assuring a complete drying of the hard to reach, continuous non-stop drip areas. the next day i go over the entire car with a quick detailer & microfiber towel...a panel at a time. lastly...including the wipe down of the jambs and inside of the rims (hard to reach i know), wheel wells and exposed underside from behind... suspension/muffler/plastic/etc. dress the tires with a foam applicator, wipe off the lip & clean the glass. almost a mini detail.
this is the way i roll.
