After my last service repair (brake booster repair/replace - that part went well) months ago on my year 2001 XC70 ~135K miles, I noticed that my front windshield has some vertical streaking. The service place (a Volvo dealer this time) gave me a the usual complementary car cleaning wash. I could not remove these streaks by trying to clean hard while pumping gas.
Does anyone have any specific experience with this and a specific fix that works?
Thank you.
