Ateca (basically the same car) wipers are exactly the same.
The only way to cure them is to fit better quality ones, Bosch wipers get excellent reviews on the Ateca forums, no noise and do a better job of water removal.
Bit expensive but I suppose you get whet you pay for!.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
