I think I have it...
This morning I took the car through a car wash (I know, I know...but it's too cold here and it was a touchless wash).
I spent about three hours on the car after the wash...leather/interior treatment...wiped down the engine bay...cleaned the windows...vaccuumed...
After that, the floor in the garage looked dirty, so I vacuumed and mopped the floor.
After cleaning the floor, I was walking around to see if I missed anything, and I saw the brake side of the wheels looked dirty. So, I jack up the car, removed all four wheels, put some Z-6 on the inside, and cleaned the wheel wells.
Seems like I'm never satisifed...it was fun though and the car looks good.
