How do you wash your car?

[butterfingers]

smudges? could be great marks maybe? If its black likely could be tar/road grime and maybe use something like Stoner Tarminator to remove!

Get some good protection over the car to stop things from adhering as easily on the paintwork!

I wax twice a month.

I'm sure it's something a clay or a polish can get rid of. I just don't want to do any abrasive work myself.
