This weather especially the blades will stick to the screen stretching the thin rubber each time you use them until they finally rip, might be stuck to the screen for weeks between use this weather, so lift them regularly.

They need to be cleaned well so nothing on them to form an adhesive, and if you can, leave them off the screen whilst parked for extended periods on your driveway (some cars this is awkward because they are parked under the bonnet rear edge as it were), and every now and again lift them gently.

They also develop a natural lean because of the direction they were travelling when they 'parked', so every now and again when you think about it lift the blades and 'park' them leaning the other way, this also helps to reduce judder, i do this out of habit now every time i've used the wipers and leave the car, and yes my blades last many years.

Also if use only use the wipers and washers to clear dead insects that have been welded on by weeks of blazing sun, you might as well be trying to clear a surform blade the same way.

I bought a set of Bosch wiper blades last June, 2 aero-types

I got the same for my car when I bought it in 2013. They still work well, only minor streaking and quiet. I'm amazed really because I have usually had to buy blades every year, and these ones have had no special treatment, apart from the obvious like thawing the windscreen in winter before using them. Based on my experience I would say that the Bosch items are very good.
