My 958.2 eats windshield wipers... anyone else?
My 958.2 chews through windshield wipers. I keep getting a set of streaks across my line of vision from the driver's wiper, on the high end. My last 4 sets of wipers and within 2-3 uses the streaks start, and get worse over time. 2-3 months I've got to buy another set because the last 3" or so winds up just being a smeared mess. I've burned through an OE set (dealer raped me on those, ouch), 2 different sets of Michelins and most recently a set of the Bosch "OE" ones.
The windshield was brand new (I took a big rock hit when the car was a week old) as of this past February. I've gone over the windshield with a razor, scraping it clean... and I'm still eating blades. Same spot each time. They work great and clear perfectly for 2-3 rains... then the streaks come back.
I don't recall my 958.1 being like this. All I can think of is that there is *something* on the windshield.
I realize it's a "hard to dx over the internet" thing but anybody got any ideas?

Where are you buying your wipers? They may have been on the shelf past their optimum age. Have you clayed your windshield. There is special windshield cleaning clay, that may help also, but I'll bet you will have better luck if you pay the extra bucks and buy a set of OE wipers from one of the major on-line retailers.

My current set I bought at AutoZone. I know at least one set came from WalMart. The OE ones obviously came from the dealer. They all failed in the same manner.
Windshield cleaning clay? Ok off to the Googles.

My 958.1 doesn't appear to eat blades but, it definitely streaks more than I have experienced in other vehicles. There was also a fair bit of judder/skipping. The judder seemed to be improved by cleaning the blades themselves with a bit of washer fluid. I would suggest cleaning the inserts more regularly and seeing if it helps the streaking.
The tearing in such a short time frame is a problem I've never experienced. I'd try the clay bar or the zaino glass polish (no polish if you have a coating on the glass) and then apply some RainX or similar to see if that helps decrease the wear and tear.
As an aside, do the auto wipers on your 958 suck as well? I have them turned to the highest sensitivity and even then if it is not a consistent rain they don't run. I can have a heavy mist that has totally obscured my view out of the windshield and they do nothing. I know in the BMW world there is a base sensitivity setting in the software that can be adjusted. My dealer says Porsche does not have that function in the software. This seems odd to me.

Not sure if it would help or not, but you could try this rather obscure product from Porsche to specifically help clean that area up..... https://www.suncoastparts.com/product/PKWWCL.html

Take a wet eyeglass cleaner wipe and wipe the wiper. You will be amazed at how much road grim gets on them. I do this about once every three months. Keeps them streak free.

Both of my CDs have no issues with windshield wipers and no streaking, either (except for that pesky bug on one of them that I need to clean!)

These wipers seem to last just about a year - then they start streaking: https://www.aliexpress.com/item/26-2...945782386.html at $13/pair, I don't feel it's one of my major Cayenne costs. They look identical to the OE/Bosch ones. I usually order a few pairs.

I did clean the windshield, applied some synthetic liquid wax that I use on the clear bra , buffed the windshield . Also applied the same on the wipers edge , worked like a charm
