Often the problem is with machine car washes where the windscreen is
sprayed with wax as part of the final process.

Yep, guaranteed way to end up with an opaque smeary mess of traffic
film and dead insect when the wipers are used the first after a few
weeks of idleness in summer.

Screen wash additives tend to work better once this wax is removed from
the glass.

And shifting the wax can be a right PITA.

Can't see the point in washing a car, it'll only get dirty again.

Me neither. I do lend my car quite a bit and the
buggers almost always wash it. Dunno if they are
too ashamed to be seen in such a dirty car or
whether its their way of saying thank you.

Once when I had almost got bogged in a dirt road
and the car was even more filthy than usual, one of
the cops who pulled me over for a breath test as
they do here quite often just grinned and said it
must the be dirties car in the town.

Its bright yellow and lives under the big
trees outside so its filthy most of the time.

Not to mention stood out in a gale with
accompanying rain pressure washes it anyway.

Doesn't work very well here.

Salt? Well maybe but the quantity fo water sprayed about underneath
from a pressure washer is nothing compared to the road spray from a
wet road...
