I had this problem with new LR wipers after a few weeks got shot of them and fitted Bosch wipers from a car acc shop , silent and not a squeak from them

It might have something to do with the screen wash you are using marc.

Clean the blades with vinegar! Did it. Not had a problem since.

Vinegar is the simple and inexpensive solution to many and varied problems. On my old Land Rover any seized bolts could be released after applying a small amount of vinegar for a few minutes. It works staggeringly well. Also great for cleaning many surfaces, including windows, carpets, metal and paintwork. It is so good that I swear that if it were invented today and put in a fancy bottle and sold for £10's - people would queue to buy it. I kid you not !

The Silencio wiper made a difference; a new wiper arm cured it 100%.Now silent. and i mean sielent. i ish i had done this months ago instead of putting uo with it.

the original arm was bent and this was evident when holding up a new ar to compare,

Taking the RRS to Paris today and so it can all it likes now!
