Hello, I recently moved. Our two cars are now standing outside (with forest edge about 50 meters away). I wash the cars every week by hand. On the paint there are now “unbelievable” impurities already after a few hours after washing. It is about 2 cm long, yellow stripes (preferably on the horizontal areas like hood and roof). These are first very soft and can still be wiped off with a soft cloth. After a short time the strips are dried up and can only be removed with effort and with the help of an insect sponge. Even longer soaking with water only helps conditionally or. unsatisfactory. Even a brush wash in the washing system holds the strips up. Who can help me and tell me what it is about at all. I am also grateful for tips for easy and gentle removal (the wax layer should not be destroyed). D ANKE in advance for your answers photos related…
