When I first got my car, it was in "not to my liking" standard. I spent about 2 hours cleaning the interior, including removing the rear seat, and vacuuming underneath. While the leather was cleaned thoroughly, and conditioned. Vacuum, Vacuum, vacuum, that was my first focus. Second priority was to clean and condition the leather.
Prior to washing the car, I must've spent about 1 hour trying to clean the wheels. Those 220s are pain in the neck. Now, it's a breeze to wash those wheels; thank God for Sonax, and Wheel Woolies brushes.
It's all love, and pain, but it's all good.
