I greet you and come with the request for advice:On the windshield of my W 204, during the wiper organ behind the windscreen wiper veil or a film, which makes the view in darkness and naturally in rain or drizzle collosally difficult. In my opinion, the reason lies in a car wash, which my wife visited and probably booked protective wax for it. Since then I have washed the windshield several times and also cleaned with window cleaning agents. h the wiper gums, but nothing brought success. Can someone help me with a good advice, or there are people with similar problems. I would like to thank you already for good advice and wish everyone a good ride. Kristian.
