Can anyone recommend a GOOD windscreen washer additive which DOESN'T leave you with a smeared or greasy windscreen. I've tried many and even after cleaning windscreen with undiluted additive or vinegar, still have same problem after I use washers.
I remember ther choice of the local ned's with flashy cars was always Clearalex which comes in a small sachet in powder form.....must be good if they used it in their cars........Have you checked to make sure that your fluid container in the car and pipes to the washer jets are clean?
