I always start with a good vacuuming, Then get the dash, door panels, lower B/C pillars, and upper A pillars with Natural Shine. Then I go over the seats with leatherique pristine clean leather cleaner. If the windows are dirty I use clearvue glass cleaner. Before winter, and after winter I shampoo the carpets, and rejuvenate the leather with leatherique rejuvenating oil.
I also remove the front and rear seats in the Spring to vavuum and shampoo the carpet where the vacuum is too fat to reach!
Engine: I use simple green and high pressure (low around intake and alt.) If I want a shine I use Hot Shine, and a Natural shine for a factory look.
Exterior: I wash at a minimum of once a week (but everyone knows how I keep my car lol) I clay when I feel that the paint isn't smooth as it should be, probably once every other month. Then I usually put one or two coats of Zaino Z2 or Z5, then go over it with Z6 Ultra clean gloss enhancer. I also put a coat of natural shine on the Specials body cladding.
I put a coat or two of Hotshine gel tire shine on the tires, and the car is clean...
95% of the above listed is a normal cleaning for me... about 6-7 hours worth other then that Its a 2 day process, including highspeed buffing, polishing, and sealing.... Im OCD
