I'm wondering how to clean the dirty windshield of the two MAN Lion Coach of the base game, without DLCs. When I activate the washers in rainy day, when the rain stops the windshield still dirty, It's like a layer of dust that darkens the view. The rear view mirrors look dark. And the night's routes are so dark that even with the long distance light, I can't see the other cars.
I've tried to clean my bus in the 'coach wash' machines, in the free ride option, but when the bus is inside, there is no popup with options to wash the bus.
I'm level 4, all unlocked, but I can't use or I don't know how to use the truck wash machines, for example in the service station of Hamburg.
I thought that changing the Lion Coach by the Lion Coach C the problem would be solved because the Lion Coach C never was used, but his windshield also is dirty!
It's a bug of the game?
Thanks a lot
