What to do to stop car windscreen wipers juddering and squeaking? (Mazda 6

If I replace them, they are quiet and effective for a month or so then the
problem returns.

Looks like there's something smeary on the windscreen, but using halfords
glass cleaner doesn't seem to resolve it.

On one of my previous cars I had similar symptoms which turned out to be a
loose spline on the wiper arm causing the wiper blade to be damaged where
it was hitting the side of the window.
