I never had a wiper juddering issue. I avoid getting car wax on the windows.

In the Australian outback, pretty much every time one fills up the car with fuel we wash the windscreen, headlights & brake lights.

If the supplied squeegee is a bit dodgy I use my own. Also I lift the wipers & give them a quick wipe every time. Procrastination, mankind's greatest labour saving device!

Tried cheap ones, tried mid range ones all judder. Finally spent some money on these METO T6 Silicone Windshield Wipe Blades off Amazon.
Perfect, no judder, no noise.

I haven’t changed my wipers since buying from the dealer 3 years ago and 40,000 miles. But I do deep clean the windscreen. It involves washing as normal firstly then using a safety razor, from the old style razor blades, and going over the entire windscreen and scraping off the layer of grease and road grime. Spray the windscreen with Auto Glym fast glass as you go from top to bottom. You’d be surprised what cr4p you remove. Never had any judder or smear.

I use Rainex on all my vehicles, and never seen to have squeaky wipers. It's amazing how the rain runs off the screen.

I’ve also switched from Bosch to Valeo. They’re good for 3 years +.

We have Bosch wipers on both of our cars and never had any problems with them.

Always use cheap ones off ebay for about £12 a set front and back. Never had a problem with them or with MOTs 3 x FL1 2 manual + 1 auto
