Wow! That's a lot of work. I use the garden hose to loosen the fine dirt and dust, then take my favorite bucket of wash soap w/mit and wash it down good, bugs and all. I'll finish washing the wheels last, brake dust and all. Then hose it down again to chamois off. I use Onyx in between yearly wax jobs as it has Carnuba wax with solvents to loosen up grime and still give it the nice finish. Get out the vacuum and go to work on the interior along with wiping down seats and dash. At outings I carry Winners Choice for detailing. Oh yeah, always have semi hard rock on too!
