Squeaky Brand New Bosch Wiper Blades

DazedByTheLight

My wipers are squeaky even though I have replaced them with brand new Bosch wipers, cleaned the windscreen and the wipers.

I have read somewhere that it could be due to how the wiper blades are angled against the screen. Anybody have any ideas how this works or what else it could be?

They are absolutely doing my head in, so much so that even though it may be raining heavily I don't turn my wipers onto fast because they don't make hardly any noise when on slow or when I use them manually.

Please help!

Buy some Rain-X and apply it to your screen. Then you won't even need to use the wipers.

Try refitting? Upside down/on the wrong arm?

Gosh I only buy Bosch because I hate that sound.....good luck!!

You can twist the wiper arm with a spanner. Just give it a slight bend. Works every time!

So the arm is parallel to the screen

For a bit more detail, I'm quoting the following from the Citroen Picasso owners forum;

Squeaky Windscreen Wipers

First wet the screen and now turn on the wipers and then turn OFF the ignition when the blades are half way thu their sweep (45 degrees). Now look at the edge of the blade. They should be trailing the arm, i.e. if the blade is going up the screen the edge should be towards the bottom of the screen. If they are, then active the wipers again and stop them on the way down. This time the edge should be pointing at the top of the screen.

If they are not or one of them is NOT then it's being pushed across the screen NOT being pulled and this will give rise to noise.

The cure -Allow wipers to sweep across the screen and when they are at 45 degrees (halfway) switch OFF the ignition. Now remove the blade assembly so that you are left with just the bare arm. Lay this on the screen and check to see if the end of the blades retaining hook lays flat on the screen. If it doesn't then you need to twist the arm so that it does. To do this hold the arm about 1/4 way up from spindle in a pair of grips, protect the arm with a cloth and then using another pair of grips 2/3 the way up apply a rotating motion.

Lay the hook on the screen again and recheck. When satisfied, refit wipers and try again. The blades should then change direction and trail the arm on each sweep.

Gave up on noisey Bosch long ago. I only buy the cheap blades from Lidl or Aldi now, and have not had a problem since. By the way, you're in luck, Aldi are doing wiper blades this week. Infinitely cheaper than Halfrauds, and better.

Thanks everyone and in particular deiselglider for an excellent answer.

You say you cleaned the screen - what with?

Try NEAT screenwash & newspaper, you'll be surprised just how greasy the glass is, at the moment.

You could also clean the blade edges, with tissue & screenwash, as you'll probably have loaded them with road grease now!!
