Do you know that? The windscreen wiper goes to the left and cleans nicely. It goes to the right and smears something. A few streaks only, but still visible and disturbing. It always runs like this, at every temperature, at every bad weather, whether now is almost only water or like the last days, often only little moisture from cars driving ahead, mixed with road dirt. New leaves have not brought any improvement. (If I could only reprogram the windscreen wiper that it could Always left stops in the interval – I would always have clean windows.) Does any of you have any idea what to do? Are there working nano-tech stories? Appreciative for tips. The “many-in-darkness and bad weather riders”.
