Moin, after my car wash in the evening, I noticed that my headlights are full of tiny stone hits. They are also only minimally visible on the surface and when the headlights are switched off. I tried to wipe them away anyway, in the hope that it is only dirt, but unfortunately did not succeed. My car was running 12 tkm and not very old. If that is not normal I would be a little surprised. What I put on my windshield wipers is the Sonax Xtreme brilliant shine more detailed. But it would hardly do that, wouldn’t it? In the pictures it looks a little more extreme than it really seems, but hopefully you see what I mean.
