Windshield stains and strong reflections

Hello, I’ve been thinking about posting this question here for a long time, but I decided to do it. I’m driving a Ceed GT MJ22. I’ve been bothered for a long time that the dashboard with loudspeakers, vents etc is strongly reflected in the windshield. Do you have the same problems or what could that be with me? I clean the windows regularly inside and outside, yesterday also made with silicone and wax remover and the dashboard also with so cockpitre After cleaning, I only saw yesterday, when I was heading towards the sun, that there are some spots on the disc, but I can’t get rid of them with any means. But can you really only see if the sun is shining directly on it, otherwise not, but these could also trigger the reflections or? Can they also be in the disc, or is that not possible? I already have I was driving, it was never as strong with the reflections as with my Ceed. Maybe someone can give me tips that have the same problems. Or just ignore it because you have no way to change it?
