Washing a white car

Blow dry your car with the leaf-blower.

have you had this car a while? Maybe the previous owner treated the black stuff with a 'black again' type product and a little rolls off when you wash.
I'd clean that with a Klasse All in One type product. Maybe even take the clay bar too it while your washing.

Sounds like you didn't clean the mirrors fully.
