You're way keener than I am mate!
I drove milk tankers for close to twenty years.
Every day I had to wash that truck with bucket and scrubbing brush from the front number plate to the rear tail-light lense.
And every bit in between.
(Car-wash-type machinery was too hard on the trucks; damaging too many mirrors, lights, and aerials.)
When I left that job I vowed I would never wash another motor vehicle again in my life.

And only twice have I broken that vow.

She washes them.

Or any other mug I can con or cajole in to doing it.

But
not
me!
